Weight gain after breast cancer diagnosis, particularly following adjuvant chemotherapy, is a common occurrence that is associated with increased recurrence risk and reduced survival.
It is common to gain weight after starting chemotherapy for breast cancer. This weight gain is not just cosmetic; it is linked to a higher chance of the cancer coming back and lower survival rates. Patients should be monitored for weight changes during treatment, as preventing this gain may improve long-term outcomes.
Weight gain after diagnosis has been frequently reported for breast cancer patients, especially among women receiving systemic adjuvant chemotherapy... women with weight gain exceeding the median of 5.9 kg were 1.5 times as likely to relapse and 1.6 times as likely to die.
Why this rating
Based on prospective cohort studies, but the paper notes that prospective studies specifically addressing the relative importance of weight gain remain to be fully conducted.
