Women who gain weight after being diagnosed with breast cancer could more than double their risk of dying from the disease, say researchers.
They say the danger is 2.4 times higher for an obese woman than one of normal weight and rises 14 per cent for every extra 11lb.
The data was presented yesterday at the American Assocation for Cancer Research's conference in Philadelphia.
Previous research showed weight gain at any stage can increase the risk of breast cancer by up to one and half times, but did not look at the risk of death. The new study involved 4,000 patients taking part in research started in 1988 at centres in three American states. They were surveyed about post-diagnosis weight, weight gain, physical activity and diet.
Researchers at Johns Hopkins Bloomberg School of Public Health, Boston, identified 121 breast cancer-related deaths.
