A study of over 540,000 women in the UK has examined the relationship between diet and colorectal cancer risk. The findings suggest that certain dietary factors, such as calcium, may be associated with a lower risk of colorectal cancer, while others, like alcohol, may increase the risk. The role of other foods, including lactose-containing products, spicy food, and dairy products, in relation to colorectal cancer risk is also being explored, with some studies indicating potential protective effects.
