This is not only the most common type of skin cancer, but the most common type of cancer in humans. About 8 out of 10 skin cancers are basal cell carcinomas (also called basal cell cancers). They usually develop on sun-exposed areas, especially the head and neck. Basal cell carcinoma was once found almost entirely in middle-aged or older people. Now it is also being seen in younger people, probably because they are spending more time out in the sun. When seen under a microscope, basal cell carcinomas share features with the cells in the lowest layer of the. | Breast Cancer Early Detection The importance of finding breast cancer early The goal of screening exams for early breast cancer detection is to find cancers before they start to cause symptoms. Screening refers to tests and exams used to find a disease such as cancer in people who do not have any symptoms. Early detection means using an approach that lets breast cancer get diagnosed earlier than otherwise might have occurred. Breast cancers that are found because they are causing symptoms tend to be larger and are more likely to have already spread beyond the breast. In contrast breast cancers found during screening exams are more likely to be smaller and still confined to the breast. The size of a breast cancer and how far it has spread are some of the most important factors in predicting the prognosis outlook of a woman with this disease. Most doctors feel that early detection tests for breast cancer save thousands of lives each year and that many more lives could be saved if even more women and their health care providers took advantage of these tests. Following the American Cancer Society s guidelines for the early detection of breast cancer improves the chances that breast cancer can be diagnosed at an early stage and treated successfully. What are the risk factors for breast cancer A risk factor is anything that affects your chance of getting a disease such as cancer. Different cancers have different risk factors. For example exposing skin to strong sunlight is a risk factor for skin cancer. Smoking is a risk factor for cancers of the lung mouth larynx voice box bladder kidney and several other organs. But risk factors don t tell us everything. Having a risk factor or even several does not mean that you will get the disease. Most women who have one or more breast cancer risk factors never develop the disease while many women with breast cancer have no apparent risk factors other than being a woman and growing older . Even when a woman with risk factors .
