This phase II trial tests whether fisetin works to improve physical function in women who have received chemotherapy for stage I-III breast cancer treatment. Fisetin is a naturally occurring substance that is found in strawberries and other foods. Fisetin eliminates cells that have undergone a process called senescence. Senescence is when a cell ages and permanently stops dividing but does not die. Over time, large numbers of these cells build up in tissues throughout the body and can release harmful substances that causes inflammation and damages nearby healthy cells. Studies have shown that chemotherapy causes a build-up of these senescent cells. Giving fisetin may eliminate senescent cells and improve physical function in postmenopausal women who have received chemotherapy for breast cancer.
PRIMARY OBJECTIVE: I. To determine the effect of fisetin on physical function, as assessed using the 6-minute walk distance (6MWD), in frail older breast cancer survivors. SECONDARY OBJECTIVES: I. To determine the effect of fisetin on other measures of physical function (grip strength, short physical performance battery \[SPPB\], frailty phenotype, physical function component of the 36 item short form survey \[SF-36\]). II. To determine the effect of fisetin on fatigability (Borg Rating of Perceived Exertion \[RPE\]). III. To determine the effect of fisetin on neuropathy (Quality of Life Questionnaire - Chemotherapy-Induced Peripheral Neuropathy 20 \[QLQ-CIPN20\]). IV. To determine the effect of fisetin on cognitive function (Patient Reported Outcomes Measurement Information System \[PROMIS\] cognitive function short form). V. To determine the effect of fisetin on health-related quality of life (SF-36). VI. To determine the effect of fisetin on sleep (Insomnia Severity Index \[ISI\]). VII. To determine the effect of fisetin on anxiety (GAD-7). VIII. To determine the effect of fisetin on depression (PHQ-8). IX. To determine the effect of fisetin on local and distant recurrence free survival. X. To determine the effect of fisetin on breast cancer specific survival and overall survival. XI. To evaluate the safety and tolerability of fisetin (physician and patient-reported Common Terminology Criteria for Adverse Events \[CTCAEs\]). XII. To estimate rates of adherence to fisetin (pill diary). EXPLORATORY OBJECTIVES: I. To determine the effect of fisetin on p16 expression in peripheral CD3+ T-cells. II. To determine the effect of fisetin on circulating senescence-associated secretory phenotype (SASP) inflammatory factors. OUTLINE: Patients are randomized to 1 of 2 arms. ARM A: Patients receive fisetin orally (PO) on days 1, 2, and 3. Treatment repeats every 2 weeks for up to 8 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood samples throughout the trial. ARM B: Patients receive placebo PO on the trial. on days 1, 2, and 3. Treatment repeats every 2 weeks for up to 8 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood samples throughout the trial. After completion of study treatment, patients are followed up yearly for up to 3 years.

RECRUITINGChange in 6-minute walk distance (6MWD)
The 6MWD is a validated measure of physical function. Participants walk at their own pace for 6 minutes and distance (in meters) is measured at the end. Will be treated as a continuous variable. Its distribution will be transformed to normality as appropriate, Initially, a simple t-test will be used to compare the means of 6MWD at Day 60 by treatment groups.
Time frame: Baseline to day 60
Change in grip strength
Generalized estimating equation (GEE) models will be fitted. The variables also will be dichotomized (e.g., \< median, \>= median) and GEE models for binary data used to access change in grip strength. Grip strength will be obtained using a hand dynamometer.
Time frame: From baseline to day 60
Change in Short Physical Performance Battery score
GEE models will be fitted. The variables also will be dichotomized (e.g., \< median, \>= median) and GEE models for binary data used to access change in short physical performance battery score.
Time frame: From baseline to day 60
Change in frailty phenotype
GEE models will be fitted. The variables also will be dichotomized (e.g., \< median, \>= median) and GEE models for binary data used to test treatment effects over time.
Time frame: From baseline to day 60
Change in physical function component of 36-item Short Form (SF-36)
GEE models will be fitted. The variables also will be dichotomized (e.g., \< median, \>= median) and GEE models for binary data used to test treatment effects over time.

Adverse events rates
Measured by National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version (v.)5. Adverse events will be determined at each time point per patient as the presence (yes/no) of toxicities (CTCAE v 5.0) of grade \>= 2. The number of patients with adverse events will be compared by treatment arms using Fisher's exact test. GEE models for binary data will also be used to compare the proportion of patients with adverse events over time by treatment.
Time frame: Up to 90 days
Adherence rate
Measured by pill diary. Treatment adherence (yes/no) for each patient at each time point will be determined. A patient will be considered adherent (coded 1) if she took all the required capsules within the allotted time, and non-adherent (coded 0) otherwise. The number of capsules taken in the allotted time out of the total required will also be recorded. Will then compare between treatments the proportion of adherent patients and the average proportion of capsules taken within the allotted time across patients at each time point using the t-test. Time point-specific analysis will be performed since conditions for pill-taking differ between the clinic (supervised) and patients' home (self-administered).
Time frame: From baseline up to 30 days
