Weight change during breast cancer treatment: is it always of poor prognosis?

Abstract

National audienceWeight change (gain or loss) is not uncommon in patients treated for breast cancer, especially when they receive chemotherapy. Weight changes observed during chemotherapy treatment performed before the 2000s, were associated with poor prognosis, but this relation is less found in more recent studies. Changes in body composition of women treated whith current chemotherapies remains to be determined. Post-treatment regular and moderate physical activity would reduce the risk of recurrence and mortality by 24-50%, both in obese and normal-weight women
