Alcohol is the main diet related risk factor for liver cancer, probably through the development of cirrhosis and alcoholic hepatitis.7 Overweight and obesity also increase risk.8 Aflatoxin, a mutagenic compound produced by the fungus Aspergillus in foods such as grains, nuts, and dried fruit when stored in hot and humid conditions, is classified as a carcinogen by IARC and is an important risk factor in some low income countries (for people with active hepatitis virus infection).56 The major non-dietary risk factor is chronic infection with hepatitis B or C viruses.

A WCRF systematic review showed that increases in risk for each 5 cm increment in height ranged from 4% for prostate cancer to 12% for malignant melanoma.83 The mechanism is uncertain but might be related to taller people having more stem cells at risk of cancer or a factor such as insulin-like growth factor 1 having effects on both height and cancer risk.84 Undernutrition causes restricted growth, and some aspects of adequate nutrition during childhood and adolescence, such as an ample intake of energy and protein, might lead to relatively greater height and a higher overall cancer risk.83 It is not clear, however, whether better understanding of this pathway could lead to strategies for reducing cancer risk. The risk for most types of cancer increases with height.
