Skin cancer is an abnormal growth of skin cells. It is most often found on skin exposed to the sun although it may also form on areas that rarely see light. Skin cancer affects people of all skin tones, and may present differently in women and men.
There are several different types of skin cancer. Three major types are described below.
Symptoms – Basal cell carcinoma
- Usually occurs in sun-exposed areas of your body, such as your neck or face, and appears as:
- A pearly or waxy bump
- A flat, flesh-colored or brown scar-like lesion
- Usually occurs on sun-exposed areas of your body, such as your face, ears and hands. More prevalent in people with darker skin and on areas that aren’t often exposed to sun, such as the legs and feet. It appears as:
- A firm, red nodule
- A flat lesion with a scaly, crusted surface
Symptoms – Melanoma
- Can develop on normal skin anywhere on your body, or in an existing mole that becomes cancerous; affect people of any skin tone.
- In Men, it often appears on the trunk, head or neck
In Women, it often appears on lower legs
- In people with darker skin tones, it may occur on the palms or soles, or under the fingernails or toenails.
- It appears as:
- A large brownish spot with darker speckles
- A mole that changes in color, size or feel or that bleeds
- A small lesion with an irregular border and portions that appear red, white, blue or blue-black
- Dark lesions on your palms, soles, fingertips or toes, or on mucous membranes lining your mouth, nose, vagina or anus
