Rectal bleeding is the most typical early warning sign. Other signs include a persistent change in bowel habits or a marked change in size or shape of the stool, abdominal pain, cramping or weight loss. If you have any of these signs of disease, see your physician right away. Your chance of developing colon cancer decreases when you eat a diet that is rich in high-fiber foods, such as fruits, vegetables, whole grains, and legumes. Regular exercise and moderate alcohol also reduces your risk.
Skin cancer is the most common of all cancers.
It most often occurs among older, fair-skinned people. There are more than three types of skin cancer. About 75 percent are the basal cell type. They develop in the layer of cells that forms the base of the epidermis, usually on the face and ears. Although once thought to be a disease of middle or older age people, this type of cancer is being increasingly seen in younger people.
