Skin cancer is the most common form of cancer in the United States, and understanding it is the first step toward prevention and treatment. It develops when skin cells grow abnormally, often due to sun exposure. Here is more information on this condition, including its causes, symptoms, and the various treatment options available to patients:
What Is Skin Cancer?
Skin cancer is the uncontrolled growth of abnormal cells in the epidermis, the outermost skin layer, caused by unrepaired DNA damage. This damage triggers mutations, which lead the skin cells to multiply rapidly and form malignant tumors. There are several types of skin cancer, with the most common being basal cell carcinoma, squamous cell carcinoma, and melanoma.
Basal cell carcinoma and squamous cell carcinoma are the most frequent types, and they are less likely to spread than melanoma. Melanoma is the most serious type of skin cancer because of its potential to spread to other parts of the body if not detected and treated early. Each type originates from different cells within the epidermis, which affects its appearance and growth patterns.
How Does Family History Contribute?
A family history of skin cancer, particularly melanoma, can increase an individual’s risk of developing the disease. Specific gene mutations can be passed down through families, making skin cells more susceptible to damage from UV radiation. If you have a first-degree relative who has had melanoma, your own risk is elevated.
Genetic predisposition does not guarantee you will develop this condition, but it does mean it is helpful to be more diligent about sun protection and regular skin checks. Professional guidance is an option for individuals with a strong family history of melanoma to understand their personal risk better. Discussing your family medical history with your dermatologist is a beneficial step.
What Are the Symptoms?
Symptoms vary depending on the type, yet a new or changing spot on the skin is a common sign. For basal cell carcinoma, symptoms may include a pearly or waxy bump or a flat, flesh-colored, or brown scar-like lesion. Squamous cell carcinoma often appears as a firm, red nodule or a flat lesion with a scaly, crusted surface. Melanoma symptoms are usually identified using the ABCDE rule: asymmetry, border irregularity, color that is not uniform, diameter greater than 6mm, and evolving size, shape, or color.
What Are the Treatment Options?
The type, size, location, and depth of the tumor determine treatment. Several effective treatment methods are available to remove cancerous cells and restore skin health, including:
- Curettage and Electrodesiccation: This treatment involves scraping away the cancerous tissue with a curette, followed by using an electric needle to destroy any remaining cancer cells.
- Surgical Excision: This involves cutting out the cancerous tumor along with a small margin of surrounding healthy skin.
- Mohs Surgery: Mohs surgery is a specialized technique where the surgeon removes the visible cancer and then removes thin layers of skin one at a time.
- Cryotherapy: This involves freezing the cancerous tissue with liquid nitrogen, causing it to slough off.
- Photodynamic Therapy: Photodynamic therapy (PDT) uses a combination of a light-sensitizing drug and a specific wavelength of light to destroy cancer cells.
