A Guide to Melanoma: What to Look For, Treatment, and More

The statistics about skin cancer’s prevalence are enough to make you immediately add 10 sunscreens to your shopping cart — like how one in five Americans will develop some form of skin cancer by the age of 70 (in 2022, Khloé Kardashian underwent treatment for a precancerous tumor), or how having more than five sunburns in your lifetime can double your chance of developing melanoma. And there’s no sugarcoating the fact that, of all types of skin cancer, melanoma is the most deadly, accounting for 80 percent of total skin cancer deaths.

But there’s a but! With early detection and treatment, there is a 99 percent survival rate for stage one melanoma, according to the Skin Cancer Foundation. (Phew.) This is exactly why it’s so crucial to understand melanoma risk factors and prevention tactics, how to identify skin abnormalities, and your own family history. To get the lowdown on everything you need to know about melanoma, we spoke with a dermatologist, ahead.

What Is Melanoma?

“Melanoma is a type of skin cancer that develops from the cells that control the skin’s pigment,” Naana Boakye, MD, MPH, FAAD, a board-certified dermatologist and founder of Bergen Dermatology, tells POPSUGAR. All melanomas are cancerous, Dr. Boakye says, so “it is essential to seek medical professional help once you notice a new dark spot appear on your body that begins to change size, shape, and color.”

Just like those airport security messages, if you see something, say something. So how do you know if your unusual spot is a potential threat? You book a visit to your dermatologist, stat.

But what does melanoma look like? According to Dr. Boakye, here are the most common types of melanoma and the identifiers your dermatologist will look for to diagnose you.

Types of Melanoma

  • Superficial spreading melanoma: The most common and invasive form, this multicolored melanoma “appears as a flat or slightly elevated skin lesion” before it grows and spreads.
  • Nodular melanoma: A rapidly growing form of melanoma, nodular melanoma typically is characterized by “a raised skin bump that appears to be uniform in color.”
  • Lentigo maligna melanoma: A slow-growing melanoma that often appears in older individuals in areas that receive lots of sun exposure, like the face, legs, or chest. It has a flat appearance and begins as a small freckle.
  • Acral lentiginous melanoma: This type of melanoma usually appears as a dark spot or streak (rather than a raised bump) on areas like the “palms of your hands, soles of your feet, or under your nails.” It’s the most common form of melanoma in people of African or Asian descent.
  • Amelanotic melanoma: Unlike other forms, this melanoma is difficult to identify by color alone and is marked by the absence of pigmentation. “In some instances, the skin may indicate a reddish or pinkish hue,” Dr. Boakye adds.

What Causes Melanoma?

Scientifically speaking, melanoma is caused by an abnormality in melanocytes, the skin cells responsible for producing and containing melanin (the pigment that gives skin its color). While we’re all born with the same amount of melanocytes, our individual skin colors are dictated by the size of melanosomes (the little organelles that produce melanin pigment) inside each of these melanocyte cells. “Those with larger melanosomes have darker skin tones,” Dr. Boakye says.

Why does this matter? Melanin is what ultimately helps protect against the UV damage that’s responsible for melanoma cancer. So while every skin tone carries a significant risk of developing melanoma, lighter skin tones, which contain less of that protective melanin, are significantly more vulnerable to melanoma. But your skin tone is just one of the many factors at play.

Who Is at Risk For Developing Melanoma?

“A family history of melanoma; someone with fairer skin, eyes, and hair; someone with a history
of severe sunburns; someone with numerous moles and, in some rare cases, a weakened immune system can contribute to someone being at risk for melanoma,” Dr. Boakye says. “And while melanoma can occur at any age, the risk does increase as an individual ages.”

So yes, everyone is susceptible (in varying degrees) to developing melanoma — whether you’re born with fair or dark skin, young or old. While there are outdated myths surrounding the need for adequate sun protection among Black individuals, it’s imperative to understand that preventative measures are equally as important for those with melanated skin. In short, skin cancer does not discriminate — wear your sunscreen.

How to Detect and Prevent Melanoma

Getting your skin checked regularly by yourself and a dermatologist is crucial for early detection. “If changes to the skin are caught in the early stages of melanoma, surgical removal is an easy treatment plan that has a higher success rate,” Dr. Boakye says, noting that mole mapping (a derm tool for taking magnified photos of moles) can help detect changes to your moles over time.

Dr. Boakye also recommends limiting your unprotected sun exposure, which is one of the major factors in developing melanoma. In fact, The Skin Cancer Foundation reports that nearly “86 percent of melanomas can be attributed to exposure to ultraviolet (UV) radiation from the sun.” Wear protective clothing (think sun hats and UPF clothing) and slather on sunscreen with an SPF of 30 or more. Just be sure you’re applying (and reapplying) the proper amount for adequate protection.

Oh, and for the love of skin health, avoid tanning beds entirely. “The oversaturation of UV rays in tanning beds increases the risk of melanoma,” Dr. Boakye says.

How to Treat Melanoma

So you’ve gone to a dermatologist and they’ve identified an irregularity (typically during a thorough “dermoscopy” examination) that’s causing concern. What now?

“If there is suspicion of melanoma from the dermoscopy, a biopsy is then performed to confirm the severity of the melanoma and determine the next steps,” Dr. Boakye says.

From there, the best treatment will ultimately depend on a multitude of factors, like the stage and location of the melanoma and your overall health. “As with any condition, early detection is crucial to ensuring a better outcome. Once melanoma has grown to a more extensive state, more aggressive procedures will have to be conducted,” Dr. Boakye adds.

For early-stage cases, localized surgical removal is common practice to remove the melanoma tumor. Then, depending on the tumor’s thickness, additional bloodwork and imaging might be ordered. If the melanoma has spread to other areas of the body or there are genetic mutations involved, Dr. Boakye says that medications (to stop the mutation process) or sentinel lymph node biopsies — a procedure where blue dye is injected to locate and remove an affected lymph node — may be prescribed.

Although less common, advanced-stage melanoma may require chemotherapy and radiation therapy “to target specific areas where the melanoma has spread.”

So for everyone with skin, there will always be an inherent risk of developing melanoma skin cancer. And while we can’t always control the various factors that put us at risk, we can control our responses and preventative measures. See you in the derm’s office.
