Skin cancer is the most common type of cancer in the United States. It occurs when the skin's cells undergo abnormal changes and grow uncontrollably. While some cases are treatable when caught early, others can become life-threatening if left unmanaged. Understanding the various types of skin cancer, their causes, and treatment options offers valuable insight into this condition.
What Is Skin Cancer?
Skin cancer arises from mutations in the DNA of skin cells, leading to unchecked cell growth. These mutations are often linked to prolonged exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. This cancer can develop in any part of the skin, though it is often seen on areas frequently exposed to sunlight, such as the face, neck, and hands. Treatments and outlooks vary depending on the specific type and stage of the disease.
What Are the Different Types?
Skin cancer can be categorized into three main types based on the cells where abnormal growth begins.
- Basal Cell Carcinoma (BCC): This is the most common form of skin cancer and starts in the basal cells, which form the skin’s lowest layer. It often appears as a small, pearly bump or a flesh-colored growth.
- Squamous Cell Carcinoma (SCC): Squamous cell carcinoma originates in the squamous cells, which make up the outermost layer of the skin. SCC may present as a scaly patch, a sore that heals and reopens, or a red, rough bump.
- Melanoma: Melanoma begins in melanocytes, the cells responsible for producing pigment in the skin. It is less common but significantly more dangerous, appearing as an irregular mole or dark spot with changes in color, size, or shape.
What Are the Causes and Symptoms?
This cancer is linked to various risk factors, including UV radiation, genetic predispositions, and weakened immunity. Individuals with fair skin, numerous moles, or a history of sunburns have a higher likelihood of developing the condition. Symptoms differ based on the type of cancer but commonly include changes in the appearance of the skin, such as new growths, sores that do not heal, or changes in existing moles. Noticing these signs early may improve treatment outcomes.
What Are the Available Treatments?
Treatment for this cancer depends on its type, size, location, and progression. Medical professionals utilize many different methods to manage and remove cancerous growths.
- Mohs Surgery: This technique involves removing thin layers of skin while examining each layer under a microscope. Mohs surgery is precise and often used for cancers in delicate areas like the face, where preserving healthy tissue is beneficial.
- Excision Surgery: This approach involves surgically removing the cancerous growth along with a surrounding margin of normal skin to make sure no cancerous cells remain. It is commonly used for basal and squamous cell carcinomas.
- Photodynamic Therapy: This treatment uses a combination of light and a photosensitizing agent to target cancer cells. It may be employed for superficial skin cancers and has minimal impact on surrounding healthy tissue.
- Radiation Therapy: Radiation therapy is used to target cancerous cells with high-energy radiation. It is an option for cases where surgery is not feasible or preferred.
- Immunotherapy: Immunotherapy stimulates the immune system to recognize and attack cancer cells. This approach may have potential in treating advanced melanomas.
