Skin cancer, the most common form of cancer in the United States, develops primarily on areas of sun-exposed skin. Although skin cancer risk factors vary, the primary cause is ultraviolet (UV) radiation from the sun or from tanning beds. Fortunately, skin cancer is also one of the most preventable forms of cancer.

Overview of Skin Cancers and Pre-Cancers

Skin cancer is the most common form of cancer and is primarily categorized into melanoma and non-melanoma types.

Non-melanoma skin cancers are more prevalent and less aggressive, whereas melanoma is less common but more dangerous. Additionally, there are precancerous conditions like actinic keratosis that require attention to prevent progression to cancer.

Basal Cell Carcinoma (BCC) - The most common form of skin cancer. It usually appears as a slightly transparent bump on the sun-exposed areas of the skin, particularly the face.
Squamous Cell Carcinoma (SCC) - Another form of non-melanoma skin cancer, typically found on areas of the skin that have been frequently exposed to the sun. It often appears as a firm, red nodule or a flat lesion with a scaly crust.
Actinic Keratosis (AK) - A common precancerous skin condition that appears as rough, scaly patches on sun-damaged skin. It can develop into squamous cell carcinoma if left untreated.

Detailed Types of Melanoma

Melanoma is a more serious form of skin cancer that can develop anywhere on the body. It is known for its ability to spread deeper into the skin and to other parts of the body. There are several types of melanoma, each with unique characteristics:

Superficial Spreading Melanoma

The most common type, making up about 70 percent of all cases, usually found in young people. It spreads superficially for a long time before penetrating more deeply.

Lentigo Maligna

Appears as a tan, brown, or dark brown discoloration and is mostly found on the sun-damaged skin of the elderly.

Acral Lentiginous Melanoma

This melanoma spreads superficially before penetrating deeper and commonly appears under the nails or on the soles of the feet or palms of the hands. It is prevalent among African-Americans and Asians.

Nodular Melanoma

Usually invasive at the time it is first diagnosed and appears as a bump that is often dark but can be skin tone or other colors. This is the most aggressive type.
