MELANOMA
Melanoma is a serious type of skin cancer that develops from melanocytes, the cells responsible for skin pigment. Unlike other skin cancers, melanoma can appear in areas not typically exposed to sunlight and has a high potential to spread (metastasize) if not detected early.
Melanoma may develop suddenly or arise from an existing mole. Warning signs include changes in size, shape, color, or texture, or the appearance of a new growth. The ABCDEs of melanoma, including Asymmetry, Border irregularity, Color variation, Diameter over 6 mm, and Evolving appearance, serve as essential guidelines for identifying suspicious lesions.
Risk factors include fair skin, sunburn history, excessive UV exposure, multiple or abnormal moles, family history, age, and living at high elevations or near the equator. Early detection through a skin cancer check with medical dermatology specialists is critical, as early-stage melanoma is often curable with surgical removal. Advanced melanoma may require treatments like immunotherapy, targeted therapy, chemotherapy, or radiation.
How Serious Is Melanoma?
Melanoma is the fifth most common cancer in both men and women. When detected early, it is often curable with timely treatment. However, if it spreads deeper into the skin or to other parts of the body, treatment becomes more challenging and the outcome can be life-threatening. While melanoma accounts for only about 1 percent of all skin cancers in the United States, it is responsible for the majority of skin cancer deaths.
The ABCDEs of Melanoma
The ABCDEs of Melanoma are guidelines that help identify signs of melanoma, the most serious type of skin cancer. They are used to examine skin lesions and differentiate normal moles from potentially cancerous ones. Each letter highlights a key characteristic to watch for.
01
Normal moles or freckles are symmetrical, meaning if you draw a line through the middle, both halves match. An asymmetrical mole, where one half does not match the other, could be a sign of melanoma.
02
Early melanomas often have uneven borders. The edges may be scalloped or notched, unlike the smooth and even border of a normal mole.
03
A benign mole is usually a single shade of brown. A mole with multiple colors, such as brown, black, blue, white, or red, may be a warning sign.
04
Melanomas are often larger than 6 mm, about the size of a pencil eraser, but can sometimes be smaller when first detected.
05
Any change in size, shape, color, elevation, or other traits, or new symptoms such as bleeding, itching, or crusting, can indicate danger.
These guidelines are helpful for regular self-examinations to detect potentially malignant moles early. However, they are not definitive diagnostic tools. If you notice a mole that meets any of these criteria, it is important to see one of our dermatologist for a professional evaluation. Early detection and treatment of melanoma can greatly improve outcomes.
