How Do Preexisting Conditions Influence Cancer Risk?
Certain preexisting conditions can increase the risk of developing cancer. For example, individuals with chronic inflammatory diseases such as Crohn's disease or ulcerative colitis are at a higher risk of developing colorectal cancer. Diabetes has been linked to an increased risk of liver, pancreatic, and endometrial cancers. Obesity, another common preexisting condition, is associated with a higher risk of various cancers, including breast, colon, and kidney cancer.
