Melanoma is the most common form of cancer among young adults aged 25 to 29. Melanoma is also one of the deadliest types of skin cancer, causing more than 75 percent of all skin cancer deaths.
Malignant melanoma impacts a disproportionately high number of Oregonians. In fact, Oregon currently has the 5th highest number of melanoma cases in the nation.
The cells involved in melanoma are melanocytes, which produce melanin, the substance responsible for skin color or pigmentation. This is why melanomas often present as pigmented or dark brown or black spots on the skin. Melanoma tumors can metastasize (move to other sites in the body), often spreading rapidly to the lymphatic system and internal organs. This tendency to metastasize makes melanomas very dangerous. When caught early, the risk of death from melanoma is very low; but when caught late, the mortality rate is, unfortunately, much higher. This is why early detection is critical for treating and curing this fast-growing skin cancer.
Melanomas can often present as a new or changing mole. Two-thirds of melanomas grow within an existing mole. About one-third of melanomas grow de-novo (outside any pre-existing mole).
Overexposure to the sun beginning in childhood is believed to be a cause of melanoma. Melanomas can also have a genetic component; that is, melanoma can run in families.
Melanoma diagnosis requires an initial diagnostic biopsy. Once melanoma has been diagnosed, treatment for melanoma is essential for survival. Treatment modalities include surgical removal, radiation therapy, or chemotherapy. The type of melanoma, its depth when detected, lymph node involvement, spread of the cancer (metastasis) (local, distant, or nonexistent) determine the specific treatment regimen for melanoma.
The key to detecting skin cancers is to look for and notice changes in your skin.
To monitor pigmented spots, the American Academy of Dermatology has developed the following guide, called the ABCDEs of melanoma.

Exposure to the sun and other UV radiation (such as in a tanning bed) can lead to melanomas. Prevention is vital and involves these steps.
