FACTS: The term cancer applies to more than 100 different diseases, all of which have two things in common. As a result of genetic damage, normal cells become cancerous and can grow in an uncontrolled manner. In addition, these cells are able to invade other tissues, disrupting and destroying the structures and organs that they infiltrate. As with most cancers, melanoma develops due to genetics as well as risk factors including sun exposure, poor diet, smoking, excessive alcohol consumption and lack of exercise. Although the fundamentals of treatment - surgery, radiation and chemotherapy - have not changed in many years, advances in imaging, diagnosis, and sophisticated methods for delivering therapies have greatly improved their effectiveness.
