Breast Cancer Survivors Gain Weight at a Higher Rate than Their Cancer-Free Peers

“Breast cancer survivors with a family history of the disease, including those who carry BRCA1 and BRCA2 gene mutations, gained more weight over the course of four years than cancer-free women—especially if they were treated with chemotherapy, according to a prospective study by Johns Hopkins Kimmel Cancer Center researchers.

“Data from earlier studies suggest that breast cancer survivors who gain weight may have a higher risk of having their cancer return, the researchers say, noting that gains of 11 pounds or more are also associated with a higher risk of developing cardiovascular disease.

“For the study, the researchers reviewed a baseline questionnaire and a follow-up one completed four years later by 303 breast cancer survivors and 307 cancer-free women enrolled in an ongoing and long-term study at the Kimmel Cancer Center of women with a family history of breast or ovarian cancer. Study participants completed a baseline and at least one follow-up questionnaire between 2005 and 2013, and one-quarter of the subjects were premenopausal.”
