If you’re noticing changes in your skin, it might be a sign that you have a melanoma. Some of these changes include new itching and a change in color or size. Itching may also be associated with new bleeding. In some cases, melanoma will appear red and start to bleed. The symptoms of melanoma vary from person to person, but they are generally related to how advanced the cancer is. A mole can change texture or become hard or lumpy, and the surrounding skin may be rough. Some people find the affected area irritated or even painful. Other causes of itching moles include exposure to certain chemicals, dry skin, or peeling skin. In some cases, an itchy mole may be indicative of something else and require immediate attention. A dermatologist can help determine whether your mole is a cancerous growth. Itching could also cause by chemicals found in body lotion or sun exposure. The size and shape of a mole may also be signs of melanoma. A typical melanoma is bigger than six millimeters in diameter, although some may be smaller than that. A melanoma may have a border that is uneven or ragged. It may also be different colors than the surrounding skin. Itching skin lesions are not necessarily dangerous, but if they become multiple, itchiness is a sign of non-melanoma skin cancer.
