Is weight gain common during breast cancer treatments? will drugs or chemotherapy for breast cancer make me gain weight?

Some people gain wt: The treatment itself does not cause weight gain. But there are changes in taste that may make you eat more especailly after the chemotherapy has been completed and stopped. So watch that you eat no more than normal. Then there is little risk of weight gain.

Yes: Very common. I tell most of my patients with breast cancer to expect to gain weight. Multiple reasons, medications, decreased activity. Hope this helps.

Very common: I inform my patients that most women and men will gain weight with chemotherapy for breast cancer. Also it is common to gain weight while on anti-hormone therapy, such as tamoxifen. Hope this helps.
