Which cancers are linked to obesity?

An international team of researchers say they have the strongest evidence yet that obesity increases cancer risk; in particular cancers related to digestive organs and hormone-related malignancies.

Findings from a large review of more than 200 studies show associations for 11 out of 36 primary cancers, including oesophageal, bone marrow, colon (in men), rectal (in men), biliary tract system, pancreatic, endometrial (in premenopausal women) and kidney.

The researchers note there could be links between obesity and other cancers, but substantial uncertainty remains because of the quality of evidence.
