Researchers have found that being overweight or obese is linked with breast cancer in women past menopause, colorectal cancer, and cancers of the endometrium, esophagus, kidney, and pancreas. And it might be linked with cancers of the gallbladder, liver, cervix and ovary, as well as non-Hodgkin lymphoma, multiple myeloma, and aggressive forms of prostate cancer.

Researchers think excess weight may increase the risk of cancer because it can lead to changes in the body that include:

Immune system function and inflammation
Levels of certain hormones, such as insulin and estrogen
Factors that regulate cell growth, such as insulin-like growth factor-1 (IGF-1)
Proteins that influence how the body uses certain hormones, such as sex hormone-binding globulin
But the connection between weight and cancer risk is complicated. Studies suggest the risk for some cancer types appears to be increased more for people who were overweight as children or young adults, than those who gained weight later in life. Also, having extra fat in the waist area may raise risk more for some cancer types than having extra fat in the hips and thighs.

Even though gaining weight can raise your cancer risk, it’s not clear whether losing weight reduces your risk. But there is growing evidence that weight loss might reduce the risk of breast cancer (after menopause), more aggressive forms of prostate cancer, and possibly other cancers, too.
