The cancer may start as a small, smooth, shiny, pale or waxy lump. Or it can appear as a firm red lump. Sometimes, the lump bleeds or develops a crust. It can also start as a flat red spot that is rough, dry or scaly. Both basal and squamous cell cancers are found mainly on areas of the skin that are exposed to the sun – the head, face, neck, hands and arms. However, skin cancer can occur anywhere.
