Researchers examined 122 types and subtypes of the disease in a study and pin-pointed 32 forms of cancer with an obesity link. 13 were already identified by the International Agency for Research on Cancer in 2016 including breast, bowel, womb and kidney cancers. Malignant melanoma, gastric tumours, cancers of the small intestine and pituitary glands, as well as types of head and neck cancer, vulvar and penis cancer were identified among 19 potential obesity-related cancers for the first time in this study.

The findings of the study will be presented at the European Congress on Obesity in Venice.
