Melanoma & Its Effects on Melanated Skin
Melanoma affects people of all races, but for those with melanated skin, it can sometimes go undetected and become a deadly threat. In this blog post, we'll be discussing what melanoma is, its effects on melanated skin, and what you can do to detect and prevent.
According to the Skin Cancer Foundation, melanoma is a serious form of skin cancer that starts in cells known as melanocytes. Melanocytes can be found in the upper layer of skin and are known for producing a pigment known as melanin. Melanin gives skin its color and can be separated into two different types: eumelanin and pheomelanin.
When your skin is constantly exposed to UV radiation from the sun or tanning, it can cause skin damage which triggers the melanocytes to produce more melanin. However, only eumelanin pigment tries to protect the skin, causing it to tan or darken. Melanoma then occurs when the DNA damage from excessive exposure to UV radiation triggers changes in the melanocytes. These changes are basically gene mutations that can affect cell growth and division. It can even spread to other parts of the body if left untreated.
Superficial spreading melanoma - The most common type of melanoma.
Lentigo maligna - A type of melanoma that develops in older folks.
Acral lentiginous melanoma - The most common type of melanoma that affects POC.
Nodular melanoma - The most aggressive type of melanoma that accounts for 10-15% of all cases.
Naturally, darker skin tones have more eumelanin while fairer skin tones have more pheomelanin. Even though eumelanin can protect skin from sun damage, pheomelanin does not have the same ability. This means that people with darker skin are less susceptible to developing skin cancer compared to fairer skin tones as they lack eumelanin.
While it may be true that people of color are less likely to be affected by skin cancer compared to those with fairer skin tones, unprotected UV exposure can still pose a deadly threat. The main issue for those with melanated skin is that skin cancer like melanoma is usually diagnosed at a late stage. Not only is it difficult to treat skin cancer at this stage, but it also means that melanoma in melanated skin can be more dangerous and spread quickly when unnoticed.
As stated by the Skin Cancer Foundation, “look for anything new, changing or unusual on both sun-exposed and sun-protected areas of the body.” Melanoma can appear on the legs for women-identifying individuals and on the torso area for men- identifying individuals. However, melanomas can also develop in areas that do not get direct sunlight. This means folks have to be very vigilant when it comes to mysterious or unknown patches that develop on their skin. If you see anything fishy, immediately contact your dermatologist!
