The Truth About Skin Cancer

Myth 4: Skin Cancer Isn’t Serious

Skin cancer, particularly melanoma, can be deadly if it isn’t caught early.

Between 2,000 and 8,000 U.S. adults die each year because of basal and squamous cell skin cancers. There are about 8,400 deaths per year from melanoma alone.

“Melanoma has a propensity to spread to other parts of the body,” Hurlbert says.

Melanoma at any stage of progression typically requires surgery to remove cancerous cells. At stages 3 and 4 it has spread to other areas of the skin or lymph vessels.

Some basal and squamous cell skin cancers may require radiation after surgery to kill remaining tumor cells.

Myth 5: People With Darker Skin Don’t Get Skin Cancer

“People of any race or skin color can get skin cancer from UV, period,” Hurlbert says.

Skin cancer may appear differently on darker skin, however, and Hurlbert says it may be missed more frequently in people of color.

Research shows that Black people are more than three times as likely to be diagnosed with advanced-stage melanoma than white people.

People with darker skin also have higher rates of a rare type of skin cancer called acral lentiginous melanoma, which appears on the palms of the hands, soles of the feet, and in the nail beds.

Myth 6: You’ll Develop Melanoma Only if You’ve Had Years of Sun Exposure and Burns

Just one blistering sunburn in childhood or adolescence can more than double your chance of developing melanoma later in life.

“One sunburn is one sunburn too many and can damage your skin cells and potentially increase your risk of melanoma,” says Hurlbert, adding that multiple severe sunburns and prolonged UV exposure during your lifetime is worse because sun damage is cumulative. Still, just one sunburn can cause lasting damage.

Myth 7: A Tan From a Tanning Bed Protects You From Sunburns and Skin Cancer

No tan is healthy, Hurlbert says.

“A tan is actually a sign that your skin is in distress. It’s the skin’s damage or stress response to UV exposure,” he says.

Even if you don’t burn, sun exposure and tanning beds cause cellular damage that increases your risk of skin cancer.

And a tan doesn’t protect you from sunburn. Studies have shown that a base tan has about the same UV protection as sunscreen with an SPF of 3 or less.

Myth 8: Makeup Can Provide All the Skin Protection You Need

“It’s great that some makeups and foundations have SPF in them, but it’s not enough,” Hurlbert says. “You really want to put apply SPF 30 or higher and put on your makeup, then reapply every couple of hours.”

Reapplication of sunscreen is key, and it usually isn’t part of someone’s makeup routine. And no matter how dark your skin is, everyone should wear sunscreen and avoid being outside during peak sun times year-round, he says.

Choose a sunscreen that protects against UVA and UVB rays, is SPF 30 or higher, and is water-resistant.

Myth 9: Sunscreen Is Only Needed When You’re Outside for Hours, Like at the Beach or the Pool

Sunscreen should be part of everyone’s morning routine, even if they’re going to be indoors for most of the day, Hurlbert says.

“You may be outside during your commute, and you can get sun exposure through windows while you’re inside, too,” he says.

When you’re outside for an extended period of time, you need to reapply sunscreen every two hours, he says.

Myth 10: Only UV Exposure Causes Skin Cancer

While UV exposure is the primary cause of skin cancer, accounting for as much as 90 percent of skin cancer cases, it’s not the only potential cause.

“Skin cancer can run in families,” Hurlbert says. “We haven’t yet identified the inherited genetics of melanoma, but there are hints of what genes may be involved.”

Hurlbert says that family history is more commonly a factor in teenagers and younger adults who develop skin cancer. Prevention tactics for people with a family history of skin cancer are the same as for everyone else.

The rare skin cancer subtypes that affect the eyes, mucosa, and the bottoms of hands and feet are usually not caused by UV exposure, he says. Having a lot of moles or certain types of moles may increase your risk of skin cancer, too.

The Takeaway

Skin cancer affects 1 in 5 U.S. adults.
Melanoma is the deadliest form of skin cancer, but it’s not the most common.
Exposure to UV rays from the sun or from tanning beds is the most common cause of skin cancer.
Detection and early treatment are key to keeping skin cancer under control.
