Cancer risk factors can be broadly categorized into several groups: lifestyle-related, environmental, genetic, and biological. Common risk factors include:
Tobacco use: Smoking and tobacco use are linked to various cancers, including lung, mouth, throat, and bladder cancer. Diet and physical activity: A diet high in processed foods and low in fruits and vegetables, combined with a sedentary lifestyle, increases the risk of several cancers, such as colorectal cancer. Alcohol consumption: Excessive alcohol intake is associated with an increased risk of liver, breast, and esophageal cancers. Obesity: Obesity is linked to higher risks of cancers, including breast, prostate, pancreatic, and colorectal cancers. Exposure to radiation: Both ionizing radiation (e.g., X-rays) and ultraviolet (UV) radiation from the sun can increase cancer risk.
