Scientific research and medical expertise have highlighted the significant link between lifestyle factors, specifically obesity, and the increased risk of developing various cancers. Data from the IARC and CDC indicate that obesity contributes to at least 13 types of cancer, including colorectal, kidney, liver, and pancreatic cancers, through mechanisms like chronic inflammation and hormonal alterations.

Medical professionals, such as oncologist Dr. Khalila Choucair, suggest that approximately 30 percent of cancer cases may be influenced by diet and lifestyle. Specific risk factors identified include tobacco use, the consumption of ultra-processed foods, and diets high in fried or fatty meats. To mitigate these risks, experts recommend maintaining a healthy weight, increasing fruit and vegetable intake, and avoiding additives like sugar in beverages.
