Before MORITZ, BALDOCK, and KELLY, Circuit Judges.
_________________________________
Dr. Xiangyuan Sue Zhu appeals pro se from a district court order that affirmed the
Commissioner’s denial of her applications for disability insurance benefits (DIB) and
supplemental social-security income (SSI). Exercising jurisdiction under 28 U.S.C.
§ 1291 and 42 U.S.C. § 405(g), we affirm.

After examining the briefs and appellate record, this panel has determined
unanimously to honor the parties’ request for a decision on the briefs without oral
argument. See Fed. R. App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore
submitted without oral argument. This order and judgment is not binding precedent,
except under the doctrines of law of the case, res judicata, and collateral estoppel. It
may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1
and 10th Cir. R. 32.1.
BACKGROUND
Dr. Zhu has a Ph.D. in economics. She has worked as an economics professor, a
business analyst, and a business manager.
While visiting China in October 2017, Dr. Zhu sought treatment for recurring
abdominal pain. Doctors discovered a bowel obstruction that necessitated partial removal
of her colon and dissection of a lymph node. Pathology reports indicated the presence of
stage III adenocarcinoma. Zhu was hospitalized for nearly three weeks. Upon returning
to the United States in November, she applied for DIB and SSI, claiming disability as of
August 2017, at the age of sixty-three.
Dr. Zhu consulted with Dr. Weijing Sun, an oncologist. He noted there was “[n]o
evidence of metastatic disease,” that “she ha[d] recovered well from surgery,” and that
the tumor’s edges were negative for cancer cells. R., Vol. I at 618, 620. He
recommended she undergo chemotherapy and “genetic counseling and . . . testing for
germline mismatch repair deficiency,” id. at 619, which is “a well-established feature for
Lynch syndrome,” Y. Yuan et al., Germline Mutations in Chinese Colorectal Cancer
Patients with Mismatch Repair Deficiency, 29 Annals of Oncology 199 (Supp. 8 Oct. 1,
2018). Lynch syndrome, also known as “hereditary nonpolyposis colorectal cancer,” is a
genetic “predisposition to early-onset colorectal cancer.” Hereditary Nonpolyposis
Colorectal Cancer, Steadman’s Medical Dictionary (2014).
Dr. Zhu began chemotherapy in December 2017. Dr. Muhammad Salamat
oversaw her treatment. He noted that she experienced chemotherapy-related side effects,
2
including “mild fatigue, mild diarrhea, and temporary neuropathic symptoms.” R., Vol. I
at 679.
In the spring of 2018, Dr. Zhu was still undergoing chemotherapy. In March,
Dr. Sun reported that she was “[d]oing reasonabl[y] well” and that new CT scans
“show[ed] no evidence of metastatic disease.” Id. at 710. In regard to her neuropathy, he
noted that her fingertips were numb, but it did “not interfere with function or cause too
much pain.” Id. at 708. He filled out a medical-source statement in support of her DIB
and SSI claims, indicating various physical limitations and opining that she would miss
work or have to go home early more than four days each month. In April, Dr. Salamat
saw Dr. Zhu and reported she was “[o]verall . . . doing well.” Id. at 844. But he opined
in a medical-source statement that she could stand no more than two minutes at a time,
not lift anything, and was “[n]ot able to work at this time.” id. at 741.
Two state-agency physicians reviewed Dr. Zhu’s medical records. Dr. Gary
Coleman reviewed her records through February 2018 and concluded she could perform
light work with postural and environmental limitations. Dr. George Liesmann reviewed
her records through June 2018 and reached the same conclusion.
Dr. Zhu finished her chemotherapy in July 2018. A subsequent colonoscopy
showed “no pre-cancerous polyps.” Id. at 813. Dr. Zhu reported to Dr. Sun in late
September 2018 that she was “feeling well with no new complaints” and “[h]er bowels
[were] working.” Id. at 802. Dr. Sun observed that her neuropathy was “[g]etting better”
and he referred her to genetic counseling. Id. at 806. Dr. Zhu reported to Dr. Salamat in
October 2018 that her neuropathy had improved in her hand but not her feet, and she
3
denied experiencing diarrhea. Id. at 876-77. Dr. Salamat reported that she had “tolerated
[chemotherapy] well except [for] mild fatigue, mild diarrhea and temporary neuropathic
symptoms from oxaliplatin” (a medication used to treat colorectal cancer). Id. at 879. He
recommended a re-check in three months.
In December 2018, Dr. Zhu appeared with counsel before an ALJ for her disability
hearing. She testified there had been no recurrence of her cancer, but she had fatigue and
neuropathy in one finger and her toes. She also complained of arthritis in her right knee,
hypothyroidism, osteoporosis, scoliosis, and diarrhea with three or four instances of
incontinence. In regard to her physical capabilities, she said she could stand or walk for
five to ten minutes; sit for up to an hour; and lift “a pair of shoes” or a gallon of milk (if
she used two hands), id. at 228. Nevertheless, she indicated she could bathe, dress, feed
herself, drive a car, and shop for groceries.
A vocational expert (VE) testified that a hypothetical person of Dr. Zhu’s age,
education and work experience could perform her prior jobs if that person could (1) do
light work 1 in a temperature-controlled environment not involving unprotected heights,
excessive vibrations, and hazardous machinery; (2) occasionally climb stairs and ramps,
but not ropes, ladders or scaffolds; and (3) occasionally balance, stoop, kneel, crouch, and
crawl. But the VE testified that no prior work could be performed if that person (1) was
1
“Light work involves lifting no more than 20 pounds at a time with frequent
lifting or carrying of objects weighing up to 10 pounds,” and “a good deal of walking or
standing” or “sitting most of the time with some pushing and pulling of arm or leg
controls.” 20 C.F.R. § 404.1567(b); id. § 416.967(b).
4
limited to sedentary work; 2 (2) could never climb, kneel, crouch, or crawl; and
(3) experienced unscheduled work disruptions due to lengthy bathroom breaks,
significant rest periods, concentration difficulties, and chemotherapy-related symptoms.
On February 4, 2019, the ALJ determined that Dr. Zhu was not disabled. 3 Doing
so, he identified as severe impairments her history of colon cancer, neuropathy, and
osteoarthritis. He found that no impairment, either singularly or in combination, met or
medically equaled any impairment in the Listings. Next, he assigned her a residual
functional capacity (RFC) that tracked the first hypothetical given to the VE. He
proffered three reasons for rejecting a more restrictive RFC: Dr. Zhu’s alleged
limitations were not entirely consistent with the evidence; the medical-source statements
2
“Sedentary work involves lifting no more than 10 pounds at a time and
occasionally lifting or carrying articles like docket files,” and occasionally walking
and standing. 20 C.F.R. § 404.1567(a); id. § 416.967(a).
3
The ALJ follows a five-step sequential evaluation process:
Step one requires the claimant to demonstrate that [s]he is not
presently engaged in substantial gainful activity. At step two, the claimant
must show that [s]he has a medically severe impairment or combination of
impairments. At step three, if a claimant can show that the impairment is
equivalent to a listed impairment, [s]he is presumed to be disabled and
entitled to benefits. If a claimant cannot meet a listing at step three, [s]he
continues to step four, which requires the claimant to show that the
impairment or combination of impairments prevents h[er] from performing
h[er] past work.
If the claimant successfully meets this burden, the burden of proof
shifts to the Commissioner at step five to show that the claimant retains
sufficient RFC [residual functional capacity] to perform work in the
national economy, given her age, education, and work experience.
Wilson v. Astrue, 602 F.3d 1136, 1139 (10th Cir. 2010) (internal quotation marks
omitted).
5
of Drs. Sun and Salamat were not supported by the record or Dr. Zhu’s testimony; and
the non-examining state medical consultants said Dr. Zhu could perform a reduced range
of light work, “consistent with physical examination findings that show[ed] few
abnormalities in her functioning,” R., Vol. I at 19. Finally, the ALJ cited the VE’s
testimony and concluded Dr. Zhu could work in her prior occupations.
Dr. Zhu sought review pro se in the Appeals Council, submitting various medical
articles and more medical records, including an October 2018 lab report showing she has
a gene variant associated with Lynch syndrome. The Appeals Council denied review. As
for her additional evidence, the Appeals Council rejected it because she failed to “show a
reasonable probability that it would change the outcome of the [ALJ’s] decision,” or the
evidence did “not relate to the period at issue” and therefore would “not affect the
[ALJ’s] decision about whether [she] w[as] disabled beginning on or before February 4,
2019.” Id. at 41.
Dr. Zhu filed suit pro se in federal district court. The court upheld the ALJ’s
decision, prompting this appeal.
DISCUSSION
I. Standards of Review
“We review the district court’s decision de novo and independently determine
whether the ALJ’s decision is free from legal error and supported by substantial
evidence.” Fischer-Ross v. Barnhart, 431 F.3d 729, 731 (10th Cir. 2005). “Substantial
evidence is such relevant evidence as a reasonable mind might accept as adequate to
support a conclusion.” Frantz v. Astrue, 509 F.3d 1299, 1300 (10th Cir. 2007) (internal
6
quotation marks omitted). “[T]he threshold for such evidentiary sufficiency is not high,”
but it is “more than a mere scintilla.” Biestek v. Berryhill, 139 S. Ct. 1148, 1154 (2019)
(internal quotation marks omitted).
Because Dr. Zhu is pro se, we construe her filings liberally, but we do not act as
her advocate. See Garrett v. Selby Connor Maddux & Janer, 425 F.3d 836, 840 (10th
Cir. 2005).
II. Medically Severe Impairments
Dr. Zhu argues the ALJ erred by not designating her Lynch syndrome, shingles,
and bowel dysfunction as severe impairments. We disagree for two reasons.
First, “the failure to find a particular impairment severe at step two is not
reversible error whe[re],” as here, the ALJ found “that at least one other impairment is
severe.” Allman v. Colvin, 813 F.3d 1326, 1330 (10th Cir. 2016).
Second, the record does not support designating Dr. Zhu’s proffered impairments
as severe. “An impairment is severe if it significantly limits a claimant’s physical or
mental ability to do basic work activities.” Id. (brackets and internal quotation marks
omitted). Regarding Lynch syndrome, the diagnosis of that genetic disorder was not
presented to the ALJ even though it was available at the time of the hearing. But the ALJ
had Dr. Sun’s November 2017 report in which he contemplated a genetic origin for her
tumor. Dr. Zhu does not, however, identify any record evidence that such a genetic
predisposition to developing cancer somehow limits her ability to do basic work
7
activities. A claimant cannot base a step-two error on “the mere presence of a condition.”
Williamson v. Barnhart, 350 F.3d 1097, 1100 (10th Cir. 2003). 4
Regarding shingles, the ALJ observed that Dr. Zhu had undergone treatment for
that condition and that it had no more than a minimal impact on her ability to perform
basic work functions. Dr. Zhu identifies no contrary record evidence. See id. (observing
that a step-two claimant has the burden of “show[ing] that h[er] impairments would have
more than a minimal effect on h[er] ability to do basic work activities” (internal quotation
marks omitted)).
Finally, regarding bowel dysfunction, the ALJ acknowledged Dr. Zhu’s testimony
about “residual issues of diarrhea,” R., Vol. I at 14-15, but he determined that recent
medical records were not supportive, see, e.g., id. at 802 (“Her bowels are working”), 877
(“No diarrhea”), 883 (“Negative for . . . diarrhea”). 5 Dr. Zhu has not shown that any
4
To the extent Dr. Zhu argues the Appeals Council erred by rejecting her
additional evidence, which included her Lynch syndrome diagnosis and other
matters, we do not reach that argument. In the district court, Dr. Zhu did not raise
until her reply brief the Appeals Council’s treatment of her additional evidence. And
the district court limited its review to the ALJ’s decision. Thus, Dr. Zhu has forfeited
any argument that the Appeals Council erred in rejecting her additional evidence in
its review of the ALJ’s decision. See Singh v. Cordle, 936 F.3d 1022, 1043 (10th Cir.
2019) (“When a litigant fails to raise an issue below in a timely fashion and the court
below does not address the merits of the issue, the litigant has not preserved the issue
for appellate review.” (brackets and internal quotation marks omitted)). And because
Dr. Zhu has not asserted that her argument could withstand plain-error review, the
argument is waived on appeal. See Richison v. Ernest Grp., Inc., 634 F.3d 1123,
1131 (10th Cir. 2011). Dr. Zhu’s additional evidence therefore “plays no role in
[our] judicial review.” Krauser v. Astrue, 638 F.3d 1324, 1328 (10th Cir. 2011).
Dr. Zhu appears to contend her problems with diarrhea are distinct from
5
bowel dysfunction or “bowel incontinence accidents,” R., Vol. I at 15. But she
provides no record support for such a distinction. The ALJ considered both her
8
bowel dysfunction persisted beyond her chemotherapy. See 42 U.S.C. § 1382c(a)(3)(D)
(providing that a claimant must demonstrate she has a severe impairment that “results
from anatomical, physiological, or psychological abnormalities which are demonstrable
by medically acceptable clinical and laboratory diagnostic techniques”).
Substantial evidence supports the ALJ’s decision limiting Dr. Zhu’s medically
severe impairments to a history of colon cancer, neuropathy, and osteoarthritis.
III. Listings
Dr. Zhu argues the ALJ erred in concluding that her colon cancer did not meet
Listing 13.18(A). That listing requires “[a]denocarcinoma that is inoperable,
unresectable, or recurrent.” 20 C.F.R. pt. 404, subpt. P, app. 1, § 13.18(A). The ALJ
could find no evidence meeting those requirements. Indeed, the ALJ noted that Dr. Zhu
“underwent a right hemicolectomy for colon carcinoma,” followed by chemotherapy and
CT scans that were “consistently . . . negative for recurrent or metastatic disease.” R.,
Vol. I at 205. The ALJ did not err.
Dr. Zhu’s cancer was clearly not inoperable. See 20 C.F.R. § pt. 404, subpt. P,
app. 1, § 13.00(I)(2) (“Inoperable means surgery is thought to be of no therapeutic value
or the surgery cannot be performed[.]”). Nor was her cancer unresectable, as Dr. Zhu’s
doctors completely removed her tumor and put her on a course of chemotherapy. See id.
§ 13.00(I)(8) (stating that “[u]nresectable means surgery . . . did not completely remove
diarrhea and the three or four incidents in which she was unable “to get to the
bathroom in time,” id. at 230, and he correctly noted “she ha[d] denied diarrhea
issues in recent follow-up examinations,” id. at 15.
9
the cancer” and “does not include situations in which the cancer is completely resected
but [the claimant receives] . . . chemotherapy . . . to eliminate any remaining cancer cells
or lessen the chance of recurrence”). And Dr. Zhu’s cancer was not recurrent, as CT
scans showed no evidence of cancer. See id. § 13.00(I)(7) (“Recurrent . . . means the
cancer that was . . . entirely removed by surgery has returned.” (emphasis added)).
Nevertheless, Dr. Zhu argues that the ALJ failed to consider the genetic origin of
her cancer and her postoperative bowel dysfunction. But she cites no evidence that either
her genetics or bowel dysfunction has any bearing on whether her tumor was inoperable,
unresectable, or recurrent within the meaning of Listing 13.18(A). See Fischer-Ross,
431 F.3d at 733 (emphasizing claimant’s “step three burden to present evidence
establishing her impairments meet or equal listed impairments”). 6
Substantial evidence supports the ALJ’s determination that Dr. Zhu’s impairments
do not meet or medically equal any impairment in the Listings.
IV. Symptom Evaluation
Dr. Zhu argues the ALJ erred by finding that her statements describing the limiting
effects of her symptoms were not entirely consistent with the record. We disagree.
6
Dr. Zhu also claims that she suffers from an “immune deficiency disorder
called [L]ynch syndrome.” Aplt. Opening Br. at 22. She offers no support, however,
for characterizing her genetic predisposition to colorectal cancer as an immune
deficiency disorder. See 20 C.F.R. § pt. 404, subpt. P, app. 1, § 14.00(A)(3) (stating
that an immune deficiency disorder is “characterized by recurrent or unusual
infections that respond poorly to treatment, and are often associated with
complications affecting other parts of the body”).
10
“Credibility determinations are peculiarly the province of the finder of fact, and
we will not upset such determinations when supported by substantial evidence.” Cowan
v. Astrue, 552 F.3d 1182, 1190 (10th Cir. 2008) (internal quotation marks omitted). 7 We
will uphold the ALJ’s findings as long as they are “closely and affirmatively linked to
substantial evidence and not just a conclusion in the guise of findings.” Id.
The ALJ reviewed Dr. Zhu’s medical records and found few documented
functional impairments beyond those caused by her surgery and chemotherapy, which he
observed had resolved, with the exception of some residual neuropathy. He also
observed that during Dr. Zhu’s medical appointments, she generally exhibited normal
strength, range of motion, and no neurological deficits. Regarding Dr. Zhu’s daily
activities, the ALJ determined they were inconsistent with a person having significant
physical limitations. Finally, the ALJ noted that Dr. Zhu’s claimed functional limitations
for standing, walking, and lifting were less severe than Dr. Salamat had opined, and that
Dr. Zhu’s neuropathy showed documented improvement after chemotherapy and did not
align with Dr. Sun’s medical-source statement.
We conclude that substantial evidence supports the ALJ’s evaluation of Dr. Zhu’s
symptoms and that he applied the correct legal standards. See Qualls v. Apfel, 206 F.3d
7
The agency no longer uses the term “credibility” and has clarified that
“subjective symptom evaluation is not an examination of an individual’s character.” SSR
16-3p, 2017 WL 5180304, at *2 (Oct. 25, 2017). But the agency has not altered the
fundamental rule applicable here, that “if an individual’s statements about the intensity,
persistence, and limiting effects of symptoms are inconsistent with the objective medical
evidence and the other evidence, [an ALJ] will determine that the individual’s symptoms
are less likely to reduce his or her capacities to perform work-related activities.” Id. at
*8.
11
1368, 1372 (10th Cir. 2000) (upholding the ALJ’s credibility determination where he
“did not simply recite the general factors he considered” and instead “stated what specific
evidence he relied on”); SSR 16-3p, 2017 WL 5180304, at *10 (Oct. 25, 2017) (stating
that the ALJ’s decision “must contain specific reasons for the weight given to the
individual’s symptoms, be consistent with and supported by the evidence, and be clearly
articulated so the individual and any subsequent reviewer can assess how the adjudicator
evaluated the individual’s symptoms”).
V. Medical Opinions
Dr. Zhu argues the ALJ erred by rejecting her oncologists’ opinions about her
functional limitations. We discern no error.
Under the revised regulations applicable here, 8 the ALJ does “not defer or give
any specific evidentiary weight, including controlling weight, to any medical
opinion(s)[,] . . . including those from [the claimant’s] medical sources.” 20 C.F.R.
§ 404.1520c(a); id. § 416.920c(a). Rather, the ALJ considers the persuasiveness of those
opinions using five factors: supportability; consistency; relationship with the claimant;
specialization; and other factors, such as “a medical source’s familiarity with the other
evidence in a claim.” Id. § 404.1520c(c); id. § 416.920c(c).
The most important factors are supportability and consistency. Id. § 404.1520c(a);
id. § 416.920c(a). “Supportability” examines how closely connected a medical opinion is
8
The regulations governing the agency’s evaluation of medical evidence were
revised effective March 27, 2017. See Revisions to Rules Regarding the Evaluation
of Medical Evidence, 82 Fed. Reg. 5844 (Jan. 18, 2017), as amended in 82 Fed. Reg.
15132 (Mar. 27, 2017).
12
to the evidence and the medical source’s explanations: “The more relevant the objective
medical evidence and supporting explanations presented by a medical source are to
support his or her medical opinion(s)[,] . . . the more persuasive the medical opinions . . .
will be.” Id. § 404.1520c(c)(1); id. § 416.920c(c)(1). “Consistency,” on the other hand,
compares a medical opinion to the evidence: “The more consistent a medical opinion(s)
. . . is with the evidence from other medical sources and nonmedical sources in the claim,
the more persuasive the medical opinion(s) . . . will be.” Id. § 404.1520c(c)(2);
id. § 416.920c(c)(2). 9
The ALJ complied with this regulatory framework and his evaluations of the
pertinent medical opinions are supported by substantial evidence. In particular, the ALJ
determined that Dr. Sun’s and Dr. Salamat’s opinions—which were provided while
Dr. Zhu was in the midst of chemotherapy—were inconsistent with clinical findings
showing that she experienced few functional deficits, her testimony describing her daily
activities and capabilities, and her post-chemotherapy statements showing improving
symptoms. Further, the ALJ considered the medical consultants’ opinions and found they
were supported by detailed evidentiary narratives and were consistent with the medical
record and Dr. Zhu’s testimony. For instance, Dr. Liesmann reviewed Dr. Zhu’s medical
records in late June 2018, right before the end of her chemotherapy, and noted that (1) a
9
An ALJ must consider, but is not required to explicitly discuss, factors three
through five (relationship with the claimant, specialization, and other factors) unless
there are differing medical opinions on an issue and those opinions are equally
well-supported and consistent with the record. See 20 C.F.R. § 404.1520c(b)(2), (3);
id. § 416.920c(b)(2), (3).
13
recent comprehensive physical exam was “essentially normal”; (2) Dr. Salamat had
reported that Dr. Zhu was tolerating chemotherapy well except for mild diarrhea, mild
fatigue and temporary neuropathy; (3) any “post surgical restrictions would have been
lifted by now”; and (4) Dr. Zhu’s symptoms would likely “continue to improve” and “at
duration, they w[ould] likely be much abated[,] . . . consistent with the usual course of”
chemotherapy following tumor removal. R., Vol. I at 282.
Thus, the ALJ found the consultants’ opinions persuasive, and he adopted their
conclusions that Dr. Zhu could perform a reduced range of light work. Dr. Zhu has not
shown the ALJ erred.
VI. VE’s Testimony
Dr. Zhu argues the ALJ should have accepted the VE’s testimony that a
hypothetical claimant limited to sedentary work and who experienced unscheduled work
disruptions could not perform any of her prior jobs. But “[t]he ALJ was not required to
accept the answer to a hypothetical question that included limitations claimed by
[Dr. Zhu] but not accepted by the ALJ as supported by the record.” Bean v. Chater, 77
F.3d 1210, 1214 (10th Cir. 1995).
CONCLUSION
We affirm the district court’s judgment.
