18 Foods to Avoid to Reduce Cancer Risk

2. Fast Food

Fast food is considered ultra-processed as it generally provides minimal nutrients and is high in total fat, saturated fats, sodium, and sugars, but it can be associated with cancer risk in other ways. Frequent consumption of fast food can lead to an increased risk of obesity, and obesity may increase cancer risk. Some studies have indicated that obesity may be linked to a significant increase in the risk of developing a number of cancers. For example, in people with severe obesity, endometrial cancer is seven times as likely, and esophageal cancer is nearly five times as likely. Among people with obesity, liver and kidney cancer are twice as likely, pancreatic cancer is 1.5 times as likely, and colorectal and thyroid cancer are 1.3 times as likely.
