Silent Warning On Grandpa’s Neck

What you’re seeing on your grandpa’s neck is often seborrheic keratosis—a common, harmless skin growth that appears with age. They can look alarming—dark, waxy, and “stuck on”—and often show up on the neck, chest, or back.

They aren’t cancer and don’t turn into cancer, but they can resemble it. Any spot that changes, bleeds, or looks unusual should be checked by a professional. Most can be identified quickly and, if needed, removed easily—so it’s best to get reassurance rather than worry.
