Skin Cancer

General Information About Skin Cancer

Key Points

  • Skin cancer is a disease in which malignant cells form in the tissues of the skin.

  • Different types of cancer may start in the skin.

  • Having a fair complexion and frequent sun exposure are risk factors for basal cell carcinoma and squamous cell carcinoma.

  • Basal cell carcinoma, squamous cell carcinoma, and actinic keratosis often appear as visible changes in the skin.

  • Skin exams and biopsies are commonly used to diagnose skin cancers.

  • Prognosis and treatment options vary depending on several factors.

What is Skin Cancer?

Skin cancer begins when abnormal cells grow uncontrollably in the epidermis, the skin’s outermost layer. The main cell types in the epidermis are:

  • Squamous cells: Thin, flat cells on the surface.

  • Basal cells: Round cells beneath the squamous layer.

  • Melanocytes: Cells that produce melanin, the pigment responsible for skin color.

Skin cancer can develop anywhere but is most often found on areas exposed to the sun, including the face, neck, and hands.

Types of Skin Cancer

Nonmelanoma Skin Cancers

  • Basal Cell Carcinoma (BCC): The most common type, usually found on sun-exposed areas like the nose. It may look pearly, scar-like, or waxy.

  • Squamous Cell Carcinoma (SCC): Typically appears as firm, red bumps or crusty patches on sun-damaged skin. SCC may spread to nearby lymph nodes.

  • Actinic Keratosis: A precancerous condition that appears as rough, scaly patches and can develop into squamous cell carcinoma.

Melanoma

Melanoma is less common but more aggressive. It develops in melanocytes and is more likely to spread to other parts of the body.

Risk Factors

Factors that may increase the risk of developing skin cancer include:

  • Prolonged sun exposure or use of tanning beds.

  • Fair skin that burns easily, light-colored eyes, red or blond hair.

  • History of sunburns.

  • Family or personal history of skin cancer or atypical moles.

  • Genetic syndromes associated with skin cancer.

  • Long-term skin inflammation.

  • Weakened immune system.

  • Exposure to arsenic or prior radiation treatment.

  • Older age.

Signs and Symptoms

Skin changes to look out for include:

  • A sore that does not heal.

  • Raised, shiny, or pearly bumps.

  • Firm, scar-like areas that may be white, yellow, or waxy.

  • Rough, scaly patches that may bleed or crust.

  • Cracked or peeling lips that do not heal with balm.

Skin cancers are most common on areas exposed to sunlight, such as the nose, ears, lower lip, and hands.

Diagnosis

Diagnostic procedures include:

  • Skin Exam: Checking for abnormal spots, bumps, or growths.

  • Skin Biopsy: Removing tissue for microscopic examination. Types include shave biopsy, punch biopsy, incisional biopsy, and excisional biopsy.

Stages of Skin Cancer

Staging helps determine how far cancer has spread and guides treatment:

  • Stage 0: Abnormal cells present, but not invasive.

  • Stage I: Tumor 2 cm or smaller.

  • Stage II: Tumor larger than 2 cm but smaller than 4 cm.

  • Stage III: Tumor larger than 4 cm or spreading to nearby tissues or lymph nodes.

  • Stage IV: Cancer has spread to lymph nodes, bone, or other organs.

Staging is different for cancers found on the eyelid compared to those on other areas of the head and neck.

Treatment Options

Treatment depends on the type, stage, location, and patient health. Options include:

  • Surgery: Removal of the tumor.

  • Radiation Therapy: Using high-energy rays to destroy cancer cells.

  • Chemotherapy: Medications that kill or slow cancer cell growth.

  • Photodynamic Therapy (PDT): Light-based treatment that destroys abnormal cells.

  • Immunotherapy: Boosts the immune system to fight cancer.

  • Targeted Therapy: Focuses on specific cancer cell changes.

  • Chemical Peels and Other Therapies: Used for precancerous lesions like actinic keratosis.

Prognosis

Prognosis depends on:

  • Type and stage of cancer.

  • Tumor size and location.

  • Patient’s general health.

  • Whether the immune system is weakened.

  • Lifestyle factors such as tobacco use.

Clinical Trials and Future Research

New treatments are continuously being tested in clinical trials. Patients may consider participation to access advanced therapies.

Follow-Up Care

Regular follow-ups are essential to monitor for recurrence and manage any treatment side effects.
