Finding any cancer early and treating it quickly is important, especially in the case of melanoma. The best defense against skin cancer is paying attention to the warning signs. If there is a sudden change in the look of a mole or a new spot, see a doctor. Look for differences in color, size, shape, or surface quality (scaliness, oozing, crusting, or bleeding). Have a doctor check any dark colored spots.
Dry skin itches because it is irritated easily. If your skin is very dry and itchy, see a doctor because this condition can affect your sleep, cause irritability, or be a symptom of a disease. For example, diabetes and kidney disease can cause itching. Some medicines make the itchiness worse.
