You’ve heard all about the ABCDE guidelines for identifying cancerous moles. While melanoma—the form of skin cancer that tends to show up as a funky looking mole—is the deadliest type of the disease, it’s not the only type. And so a new or changing mole isn’t your only cause for concern.
“Non-melanoma skin cancers like basal cell or squamous cell are what we call skin-derived cancers, not mole-derived,” says Adam Friedman, MD, an associate professor of dermatology at George Washington University. Translation: They don’t show up as moles.And considering both basal cell and squamous cell skin cancers are more common than melanoma, it’s probably time you learned about their warning signs and symptoms—not to mention the symptoms of melanoma that have nothing to do with moles.
