Can I try to lose weight if I'm being treated for cancer?

You should not try to lose weight if you're being treated for cancer. For people with cancer, taking on too many challenges is overwhelming. When you are being treated for cancer, the issue of being overweight or obese is secondary. It's more important to get through the initial period of treatment and then, after recovery, to try to lower the risk of a recurrence.

If you are being treated for cancer, it's important to maintain a healthy weight. Aim to avoid losing or gaining much weight during treatment. Strict dieting is not recommended during cancer treatment. Losing weight can lower your energy level and decrease your body’s ability to fight infection.
