What is skin cancer?
Skin cancer is one of the most common types of cancer. It is an abnormal growth of skin cells resulting from prolonged exposure to sunlight or other sources of ultraviolet (UV) radiation.
It can appear on any area of the body, especially sun-exposed areas, and its severity varies depending on the type of cancer and the stage at which it is detected.
Causes of skin cancer
Skin cancer can be caused by several factors, including:
- Prolonged and direct exposure to sunlight.
- Use of tanning beds.
- A weakened immune system.
- A family history of skin cancer.
Symptoms of skin cancer
Symptoms appear as noticeable skin changes, including:
- The appearance of a new spot or mole with an irregular shape.
- A change in the color or size of an existing mole.
- Bleeding or peeling in a specific area of skin.
- The appearance of an ulcer that does not heal over time.
How is skin cancer diagnosed?
Diagnosis is made through several medical procedures, including:
- Clinical examination and observation of any skin changes.
- A dermoscopy is performed to thoroughly examine moles and skin.
- A skin biopsy is taken for microscopic examination.
- Imaging may be used to determine the extent of the disease in advanced cases.
Treatment of Skin Cancer
Treatment depends on the type and stage of the cancer. Some of the most important methods include:
- Surgical removal of the tumor.
- Cryotherapy to destroy superficial cancer cells.
- Radiation therapy to control advanced tumors.
- Immunotherapy to stimulate the body to fight cancerous cells.
