Cow's milk consumption has a complex relationship with cancer risk. Potential risk factors include hormones like IGF-1 and estrogens, which may encourage cancer cell growth. Considering this, does boiling milk make it safer by reducing these risks, or do these factors remain unaffected by heat?
Can we conclude that boiled milk is safer to consume?
Cow's milk contains naturally occurring hormones, including estrogen and insulin-like growth factor 1 (IGF-1), which have been hypothesized to influence cancer risk. Some studies suggest that IGF-1, in particular, might promote the growth of certain types of tumors, such as breast and prostate cancer. However, the impact of these hormones on cancer risk remains unclear, as many studies have not found a consistent or direct link.
