Inspect your skin regularly
Since not all types of cancer are caused by sun exposure, you should always inspect your skin, even in areas with no frequent sun exposure. If you notice any unexplained change in your skin, and especially when they last for more than 3 weeks, do not hesitate to report it to your doctor. It is important to understand the characteristics of skin cancer and be able to differentiate them from harmless moles on the skin as we will cover below. Correct inspection should be performed using a full-length mirror and a hand mirror to be able to inspect the neck, back, and scalp. After checking your head and upper portion of your torso, bend the elbows, examine the forearms, the upper arms, and palms. Inspect the lower part of your body and your lower extremities, including the space between your toes and the bottom of your feet.
