Epidemiology shows that obesity increases the risk for which of the following cancers?

• A. Breast, ovarian, and cervical
• B. Colon, endometrial, and postmenopausal breast cancer
• C. Liver, lung, and bladder
• D. Esophageal, pancreatic, and cervical

Answer: (B)

Obesity is a significant risk factor for several types of cancer, particularly colon, endometrial, and postmenopausal breast cancer. The relationship between obesity and these cancers is well-established in epidemiological studies. For example, excess body fat can lead to increased levels of estrogen, especially in postmenopausal women, which can elevate the risk of developing breast cancer. In the case of endometrial cancer, obesity contributes to a higher risk due to the thickening of the uterine lining caused by elevated estrogen levels. Furthermore, for colon cancer, research indicates that obesity is linked to an increased likelihood of developing adenomas, the precursors to colon cancer. The other options list types of cancer that are not primarily associated with obesity in the same consistent way. While there are some associations, such as with liver and pancreatic cancers, they are not as prominent or widely recognized compared to those specifically linked to obesity like colon, endometrial, and postmenopausal breast cancers. Therefore, the acknowledgment of these particular cancers in connection with obesity presents a more accurate reflection of current epidemiological insights.
