What is Skin Cancer?

Skin cancer is a disease where abnormal cells grow uncontrollably in the skin’s layers, often due to DNA damage caused by ultraviolet (UV) radiation. It is the most common type of cancer and can be life-threatening if not detected and treated early.

Classify Skin Cancer

Illness: Skin cancer is classified as a type of malignant neoplasm that originates in the skin cells.

Skin Cancer Statistics

Skin cancer is the most prevalent cancer worldwide. In the U.S., over 5 million cases are diagnosed annually. One in five Americans is likely to develop skin cancer in their lifetime. Melanoma, a severe form, accounts for over 100,000 cases yearly in the U.S.

Types of Skin Cancer

1. Basal Cell Carcinoma (BCC): The most common type; slow-growing and rarely spreads.
2. Squamous Cell Carcinoma (SCC): Second most common; can spread if untreated.
3. Melanoma: The deadliest form; originates in melanocytes.
4. Merkel Cell Carcinoma (MCC): Rare but aggressive form.
5. Actinic Keratosis (Precancerous): A potential precursor to SCC.

Health Signs and Symptoms

Early Detection: Regularly examine your skin for changes in moles, spots, or lesions.

Common Signs and Symptoms:

• New growths or sores that do not heal.
• Changes in the color, size, or shape of moles.
• Pearly, waxy, or translucent bumps.
• Red, scaly patches.
• Itching, bleeding, or crusting spots.
• A dark streak under a nail.

Anatomy and Physiology

Skin cancer primarily affects the epidermis, the outer layer of the skin.

• Basal Cells: Found in the lower part of the epidermis; affected in BCC.
• Squamous Cells: Located in the middle layer; affected in SCC.
• Melanocytes: Pigment-producing cells in the epidermis; affected in melanoma.

Causes

Brief Description: Skin cancer results from DNA damage in skin cells, often due to UV radiation.

Common Causes:

1. UV Exposure: Sunlight and tanning beds.
2. Fair Skin: Lower melanin levels increase risk.
3. Genetic Factors: Family history of skin cancer.
4. Immune Suppression: Weakened immune system.
5. Exposure to Carcinogens: Chemicals or radiation.

Skin Cancer Stages

1. Stage 0: Cancer is confined to the outermost skin layer.
2. Stage I: Small tumors without lymph node involvement.
3. Stage II: Larger tumors, still localized.
4. Stage III: Cancer has spread to nearby tissues or lymph nodes.
5. Stage IV: Cancer has metastasized to distant organs.

Prevention

• Use broad-spectrum sunscreen with SPF 30 or higher.
• Avoid tanning beds.
• Wear protective clothing, hats, and sunglasses.
• Seek shade during peak sunlight hours (10 AM–4 PM).
• Perform regular skin self-exams.

Skin Cancer Diagnosis

Diagnosis involves visual skin examination and biopsy to confirm cancerous cells.

Tests & Examinations

• Skin Biopsy: Removal and examination of a skin sample.
• Dermatoscopy: Magnified inspection of skin lesions.
• Imaging Tests: For advanced stages to detect metastasis (e.g., CT or PET scans).

Health Professionals

1. Dermatologists: Experts in skin health and diagnosis.
2. Oncologists: Manage cancer treatment, especially melanoma.
3. Surgeons: Perform surgical excisions.
4. Pathologists: Analyze biopsy samples.
5. Plastic Surgeons: For reconstructive procedures.

Reasons to See a Professional

• Unhealed sores or changes in skin lesions.
• Rapidly growing or bleeding moles.
• Persistent itchiness or discomfort.

Process to Find the Right Professional

• Consult your primary care doctor for referrals.
• Verify credentials and experience in treating skin cancer.
• Seek specialists at accredited cancer centers.

Visit Preparation

• Document any changes in your skin.
• Bring a list of medications.
• Prepare questions about treatment options.

Questions to Ask

• What type of skin cancer do I have?
• What stage is it?
• What are my treatment options?
• What are the risks and side effects?
• How can I monitor my skin in the future?

Diagnosis

A dermatologist performs a biopsy, followed by lab analysis to confirm the type and stage of skin cancer.

Procedures

• Excisional Biopsy: Removing the entire lesion.
• Mohs Surgery: Precise removal of cancerous layers.
• Cryotherapy: Freezing precancerous lesions.

Treatments

• Surgery: Most common treatment for early-stage cancers.
• Radiation Therapy: For non-operable tumors or advanced stages.
• Chemotherapy: For advanced or metastatic cases.
• Immunotherapy: Boosts the immune system to fight melanoma.
• Targeted Therapy: Uses drugs to target cancer cells.

Health Monitoring

• Routine dermatologist check-ups.
• Use apps to track mole changes.
• Regular self-examinations with mirrors.

How to Manage Skin Cancer

• Follow the treatment plan diligently.
• Protect skin from further UV damage.
• Join support groups for emotional well-being.

Nutrition Dos and Don’ts

Dos:

• Eat antioxidant-rich foods like fruits and vegetables.
• Include omega-3 fatty acids (fish, flaxseed).

Don’ts:

• Avoid high-sugar, high-fat processed foods.
• Limit alcohol consumption.

Lifestyle Dos and Don’ts

Dos:

• Adopt a healthy skincare routine.
• Engage in regular physical activity.

Don’ts:

• Avoid prolonged sun exposure.
• Do not ignore follow-up appointments.

Emergency Situations

• Sudden, severe skin infection.
• Signs of metastasis, such as unexplained weight loss or pain.

What to Do: Contact your healthcare provider or visit the ER immediately.
