WHAT IS SKIN CANCER?
I quickly did some research on moles and skin cancer because I wanted to know more. Skin cancers—including melanoma, basal cell carcinoma, and squamous cell carcinoma—can develop on normal skin, within a normal mole, or from a precancerous lesion. These precancerous lesions are changes in skin that are not cancer, but could become cancer over time. A mole, medically known as a nevus, is a benign growth of melanocytes, cells that give skin its color. Although very few moles become cancerous, abnormal or atypical moles can develop into melanoma over time. “Normal” moles can appear flat or raised or may begin flat and become raised over time. The surface is typically smooth. Normal moles are round or oval and no larger than a pencil eraser. Most moles develop in youth or young adulthood. It’s unusual to acquire a mole in the adult years. My mole was not smooth, it developed in adulthood, and was large.
