More evidence of the link between obesity and cancer, and how fat tissue and related cells ‘feed’ tumour growth. Some links with specific cancers:
- Prostate cancer – researchers from Duke University Medical Center explained at the American Urological Association Annual Meeting in 2011 that obese patients with prostate cancer have a considerably higher risk of the cancer growing and spreading, even if hormone therapy is administered.
- Breast cancer – severely obese women have a 39% higher risk of developing estrogen receptor-positive breast cancer and a 35% greater risk of triple-negative breast cancer compared to women of the same age of normal weight, scientists from the Fred Hutchinson Cancer Research Center reported in May 2011.
- Ovarian cancer outcomes – obese women with ovarian cancer are more likely to die from the disease than ovarian cancer patients of normal weight, scientists from the Cedars-Sinai Medical Center announced in August 2006. They added that fat cells excrete a hormone that encourages tumor growth.
- Colorectal cancer – obesity raises the risk of developing colorectal cancer, the American College of Gastroenterology announced in March 2012.
- Renal cell cancer – obesity may increase the risk of developing the most common form of renal cell cancer, researchers from the Memorial Sloan-Kettering Cancer Center in New York revealed in January 2010.
