Skin Cancer Diagnosis
If you notice any suspicious change in your skin, consult your doctor right away. As with most cancers, early detection increases the chances of successful treatment. Don’t wait for the area to start hurting — skin cancer seldom causes pain.
See your doctor if you notice a new skin growth, a bothersome change in your skin, a change in the appearance or texture of a mole, or a sore that doesn’t heal in two weeks. Your doctor may suspect cancer by simply looking at your skin. But to properly diagnose skin cancer, your doctor or dermatologist will need to take a small sample of your skin (biopsy) for analysis in a lab. A biopsy can usually be done in a doctor’s office using local anesthetic.
Skin cancer is generally divided into two stages:
- Local. In this stage, cancer affects only the skin.
- Metastatic. At this point, cancer has spread beyond the skin.
Because superficial skin cancers such as basal or squamous cell carcinoma rarely spread, a biopsy often is the only test needed to determine the cancer stage. But if you have a large growth or one that’s existed for some time, your doctor may do further tests to determine the extent of the cancer.
