Cancer, skin

Other names: Skin cancer

Skin cancer is the abnormal growth of skin cells, most commonly developing on skin exposed to the sun. There are three major types of skin cancer: Basal cell carcinoma, squamous cell carcinoma, and Melanoma. You can reduce your risk of skin cancer by limiting or avoiding exposure to ultraviolet (UV) radiation and checking your skin for suspicious changes.

SYMPTOMS

#

Where Skin cancer develops Skin cancer primarily develops on sun-exposed areas such as the scalp, face, lips, ears, neck, chest, arms, and hands. It can also occur in areas not usually exposed to sunlight.

Less common Skin cancers Other less common types include Kaposi Sarcoma, Merkel cell carcinoma, and Sebaceous gland carcinoma.

# WHEN TO SEE A DOCTOR

Make an appointment if you notice any skin changes that worry you.

CAUSES

Skin cancer occurs due to mutations in the DNA of skin cells caused by factors like UV radiation from sunlight. Other factors like toxic substances or weakened immune systems may also contribute to the risk of skin cancer.

RISK FACTORS

Factors increasing the risk of skin cancer include fair skin, history of sunburns, excessive sun exposure, moles, family history of skin cancer, weakened immune system, exposure to radiation or certain substances.

Preparing for Your Appointment

Be prepared for your doctor's appointment by noting symptoms, personal information, medications taken, and questions to ask your doctor about diagnosis and treatment options.

Tests and Diagnosis

Diagnosing skin cancer may involve skin examination and a biopsy to confirm the type of cancer. Further tests may be done to determine the extent of the cancer.

TREATMENTs and Drugs

Treatment options vary based on the type and stage of skin cancer but may include freezing, surgery (excisional or Mohs), radiation therapy, chemotherapy, photodynamic therapy, and biological therapy.

LIFESTYLE AND HOME REMEDIES

Prevent skin cancer by avoiding midday sun exposure, wearing sunscreen year-round, protective clothing, avoiding tanning beds & sun-sensitizing medications. Regularly check your skin for changes and report them to your doctor promptly.
