Risk factors for cancer include: tobacco, alcohol, blood pressure, unhealthy/overweight/high cholesterol/physical inactivity, family history. In men, prostate cancer is the most common type. In women, breast cancer is the most common type. Lung cancer is more lethal than breast or prostate cancer: although more people have breast or prostate cancer, lung cancer kills more people because it has higher mortality rate than the breast or prostate cancer. Tumors develop as a result of a genetic mutation within a single cell which could be due or radiation exposure, chemicals, or random error. The mutated cells that don"t die and are not killed by the immune system, continue to replicate (hyperplasia) and change in appearance and behavior (dysplasia)
