Skin cancer represents the most frequently diagnosed form of cancer in the United States. It develops when abnormal cells in the outer layer of the skin grow rapidly and form malignant tumors. While various factors contribute to the onset of this disease, ultraviolet radiation from sun exposure remains the primary catalyst.
What Is Skin Cancer?
Skin cancer occurs due to DNA mutations in the epidermis, leading to the uncontrolled multiplication of cells. This condition affects individuals across all skin types and ethnicities. Medical professionals diagnose a few common types of cancer, and these include:
- Basal Cell Carcinoma (BCC): This form typically manifests as a pink bump on the skin. It frequently affects individuals with fair complexions and appears on areas regularly exposed to sunlight.
- Squamous Cell Carcinoma (SCC): SCC presents as scaly lesions often found on the back, neck, or face. SCC behaves more aggressively than BCC and possesses the potential to spread to other organs if left unaddressed.
- Melanoma: Melanoma usually begins as a changing or evolving mole. Early detection makes the disease highly treatable, but the cancer can metastasize rapidly throughout the body, making routine screenings a necessary part of preventative health routines.
Medical providers recommend interventions based on the specific type, location, and severity of the cancer.
What Causes It?
Ultraviolet light from the sun acts as the leading cause of skin cell mutations. Sunburns and blistering indicate significant cellular damage and increase the likelihood of developing cancerous growths over time. Certain physical characteristics and lifestyle choices elevate an individual’s risk profile. Those who spend extensive periods outdoors or utilize artificial tanning beds face a higher probability of cellular damage. People possessing fair skin, light-colored eyes, and blonde hair naturally have less melanin, offering minimal natural protection against ultraviolet radiation.
Other risk factors include the presence of numerous moles or pre-existing actinic keratosis, which are precancerous lesions. Individuals taking medications that suppress the immune system also carry a heightened risk. A family history of the disease significantly raises a person’s susceptibility, but this is especially the case if you have a parent or sibling with a past diagnosis.
How Is It Treated?
Upon reaching a definitive diagnosis, a dermatologist will outline appropriate therapeutic options tailored to the patient’s condition. Available procedures can involve the direct removal or destruction of the abnormal tissue. Physicians may utilize surgical excision and cut out the lesion along with a margin of healthy skin. For more complex or recurring cases, Mohs surgery allows the surgeon to remove the cancer layer by layer, examining the tissue under a microscope until no abnormal cells remain. Other approaches include curettage and electrodesiccation, which involve scraping away the malignant cells and using heat to destroy any remaining tissue. Cryotherapy relies on liquid nitrogen to freeze and eliminate the lesion.
Confer With a Dermatologist
Maintaining regular observation of your skin helps detect abnormalities in their initial stages. Prompt identification greatly expands the available options for therapy and improves long-term outcomes. Scheduling a professional evaluation provides a comprehensive assessment of your specific risk profile. A dermatologist possesses the expertise required to accurately evaluate suspicious lesions, allowing them to provide definitive diagnoses and formulate an effective care plan.
