10 Signs of Skin Cancer

2. Open Sores and Growths

A persistent red sore, nodule, or scaly patch on the body might indicate squamous cell carcinoma. The growths have a crusty exterior and often appear in areas that experience frequent sun exposure. They can also develop on top of old scars or ulcers.

Squamous cell carcinoma can develop on any area of the body, including the genitals or inside of the mouth, though the most likely places are those sun-exposed areas: a balding scalp, or the neck, hands, arms, or face. They may also appear on the rim of the ear or the lower lip. Over the last three decades, the number of squamous cell carcinoma diagnoses has increased by more than 200%.
