The steady increase in cancer incidence rates necessitates studies of global risk factors for cancer and a search for novel methods of effective primary prevention. According to the International Cancer Research Agency (IARC, 2017), obesity also increases the risk for development of 13 most common malignant neoplasms (MNs), including breast, colon, pancreas, bladder, and endometrial cancers; the incidence of MNs caused by overweight and obesity among women is 5.4%.

Menopausal hormone therapy (MHT) for women in the early postmenopause and/or those who are younger than 60 years, and overweight control reduces overall mortality from 30 to 52% and contributes to the primary prevention of a number of MNs, including breast cancer, type 2 diabetes mellitus, and cardiovascular disease.
