Which cancer risk is increased by foods high in calcium and insulin-like growth factor?

The connection between high calcium intake and elevated levels of insulin-like growth factor (IGF-1) has been shown to have a potential influence on prostate cancer risk. Calcium can increase the absorption of IGF-1 in the body, which is a hormone that plays a significant role in cell growth and development. Elevated levels of IGF-1 have been studied extensively concerning prostate cancer, as they may promote the growth of prostate cancer cells.

Several epidemiological studies have indicated that diets high in dairy, which is a primary source of calcium, might be linked with an increased risk of prostate cancer. This association may be due to the simultaneous increase in calcium and IGF-1, leading to changes in hormonal and cellular pathways that can contribute to the development of cancer in the prostate.

Other options, while associated with dietary factors and cancer in general, do not have the same strong, documented relationship with high calcium and IGF-1 as prostate cancer does. This specific link emphasizes the importance of understanding how certain dietary components can influence cancer risks, particularly highlighting the interplay between nutrition and hormonal pathways in cancer development.
