Skin cancer can be defined as the growth of abnormal skin cells. It is a commonly found type of cancer and is characterised by locally destructive malign or cancerous growth. The cancer generally arises between the deeper layers of the skin and the superficial top layer and later spreads to other layers.
- Basal Cell Carcinoma
- Squamous Cell Carcinoma
Of these, basal cell carcinoma is the most common type of skin cancer found, closely followed by squamous cell carcinoma which occupies a second place in its incidence. Squamous cell carcinoma originates from the skin cells. Melanoma is the most dangerous and life threatening variety and is said to originate from melanocytes, the skin cells that produce pigments.
- Over exposure to sun light
Over exposure to sunlight increase the exposure to ultra violet rays that are known to be a major contributor to skin cancers. Activities like frequent tanning are known to increase the probability to this disease. People living at elevated locations or near the equator are known to be more exposed to UV radiation.
A highly suppressed immune system from certain medications or infections are also said to cause skin cancer. Cancerous growth can arise in scars and burns when these are exposed to radiations or certain chemicals as well.
Treatment for skin cancer is based on the type of cancer, age of the patient, location of cancer and the intensity or penetration of the disease. If detected and treated early, skin cancer does not cause any underlying damage and can be cured fully. The treatment procedures for treating skin involves the following.
- Laser surgery
- Micrographic surgery
- Electro surgery
- Photo Dynamic Therapy
- Excisional surgery
- Topical Medication
Skin cancer can be prevented by limiting sun light exposure during the peak sunny times, using sunscreen before going out in the sun and so on.
