What are the most common signs and symptoms of skin cancer?

Signs of non melanoma skin cancer include a new patch of skin or lump that doesn’t heal within a
few weeks. You might see changes to an existing or new mole, usually on the back, legs, arms, or
face. Melanomas are often more noticeable than a normal mole, irregular in shape, and have more
than one colour. Sometimes they itch or bleed.
