How can I tell if a skin lump is cancer? 

Only a qualified dermatologist can determine if a skin lump is cancerous by examining your lump/bump and ordering the necessary tests. 

Some warning signs of cancerous lumps/bumps include: 

• a new or unusual growth that doesn't heal within 4 weeks 

• changes in existing moles such as a change in the size, shape or colour, irregular borders, itching, bleeding, and pain 

• red or irritated patches of skin that are rough, scaly, crusty, or itchy
