Melanoma—the most worrisome and potentially deadliest type of skin cancer—can develop from an already existing mole that undergoes cancerous changes. So your healthy mole with hair sticking out of it can become cancerous. In that case, the hair would actually stop growing.
Do hairs grow out of skin cancer?
But what about a mole that has one or more hairs growing out of it? It’s a popular myth that hairy moles are often cancerous, but that’s all it is: a myth. In fact, the presence of a hair growing out of a mole may indicate that the spot is actually healthy and noncancerous.
Does melanoma have hair on it?

Can hair grow on tumors?
What is a pilomatricoma? A pilomatricoma, sometimes called a pilomatrixoma, is a rare, noncancerous tumor that grows in hair follicles.

The nodules are often mistaken for cancerous mass on the skin, such as basal cell carcinoma. It develops spontaneously, though rarely it is associated with a history of trauma at the lesion site.
What is Trichilemmal carcinoma?
Trichilemmal carcinoma (TC) is a rare malignant tumor that develops from the external root sheath of the hair follicle. It usually is found in the skin that occurs on the sun-exposed areas of the body .
What’s Merkel cell carcinoma?

Scalp melanoma is rare: it represents 2–5% of all skin melanomas and is significantly more frequent in male patients than female. It has been observed that scalp melanoma arises within congenital nevi in children and young adults, or within a lentigo maligna in the sun-damaged bald scalp of elderly men.
What does basal cell carcinoma look like when it starts?
At first, a basal cell carcinoma comes up like a small “pearly” bump that looks like a flesh-colored mole or a pimple that doesn’t go away. Sometimes these growths can look dark.
