Melanoma

Melanoma, the most serious type of skin cancer, begins in skin cells called melanocytes. Melanocytes produce the pigment, melanin, which determines the color of skin, hair and eyes. It is the leading cause of death from skin disease. Melanoma begins on the surface of the skin and can grow down into the skin reaching the blood vessels and spread around the body. When cancer spreads it is called metastasis. Melanoma can occur anywhere on the skin but often occurs on sun exposed areas of the body such as arms, face, back and legs. Melanoma cancer can also occur in the eyes, mouth or the internal organs but this is much rarer than melanoma skin cancer. It is a very dangerous type of cancer, and the patient’s chances of survival often depend on early diagnosis and treatment. Skin cancer is the most common type of cancer and is seen in people of all ages.

Causes

Skin cancer is caused by intense exposure to ultraviolet radiation from sun exposure or tanning bed usage. This can start a change in melanocytes that eventually turns them into melanoma cells.

Risk factors

  • Frequent sun exposure
  • Fair, sun-sensitive skin
  • History of sunburns
  • Reduced Immunity
  • Irregularly shaped moles
  • Previous history of melanoma
  • Older age (>50 years)
  • Hereditary conditions

Signs and Symptoms

Melanoma is often painless and usually produces the following signs:

The first sign is a change in shape, size, and color of an existing mole. It may also appear as a new irregular mole. It may appear black or blue black in color. They are typically located on the back, the shoulders or on the back of the legs. They often have an irregular border and uneven colors. Skin may become reddish or swollen and may be painful.

Treatment

Your dermatologist diagnoses melanoma by visually examining the lesions. If any lesions are suspicious, a skin biopsy will be done where a part or the entire lesion will be removed and observed under a microscope for cancer cells. If a diagnosis of melanoma is confirmed, the cancer is staged based on its severity as stage 0–IV. Treatment will depend on the stage of cancer, size and location of the tumor, and the patient’s general health. Some of the treatment options include:

Surgical treatment is the standard treatment for melanoma. Wide surgical excision is done for removal of the tumor along with the surrounding normal skin, depending on the depth of the melanoma.
