Screening means checking for disease in people who don’t have any symptoms. Not every type of cancer has guidelines for recommendation of screening – melanoma does. You have a better chance of surviving melanoma if doctors diagnose and treat it early. “Early” means finding the melanoma when it is thin. A melanoma that is thick (penetrating deeper in the skin) or bleeding is more worrisome than a thin melanoma. The best way to find melanoma early is to have regular skin check-ups from a healthcare provider who is trained to inspect skin. The American Cancer Society recommends skin check-ups for people 20 to 40 years old every 3 years. People who are older than 40 should have a skin check-up once a year. Even though these skin check-ups help increase the chances of finding melanoma early, they don’t guarantee that you won’t get melanoma or die from it, especially if it’s found after you have symptoms.
