According to Healthline, one of scalp moles' possibilities is that they're early signs of melanoma, a harsh skin cancer. Moles could indicate other skin cancers, too. Skin Check adds that other serious scalp cancers include Basal cell carcinoma and squamous cell carcinoma, both of which can be recognized by skin discoloration and the formation of multiple moles, though just one could mean one of these cancers is forming.

Like with any other area of your body, moles on your scalp are typically benign, and they most often form before age 30, per Tiege. However, you should know that moles can change shape and color, so getting them examined by dermatologists is always recommended, especially if they change while you're over the age of 50.

Unfortunately, cancerous moles on the scalp are more lethal than moles on other parts of the body, specifically when the mole has melanoma, Skin Check notes. This is most often because scalp melanomas are diagnosed later than others, so they get treated late and can prove deadly. Skin Check further notes that the scalp's blood vessels and lymphatics might incubate melanomas better than other areas of the body. Ultimately, keep a watchful eye on any moles on your scalp (or anywhere), and seek medical attention if you notice any changes in your mole's appearance.

And in case you're curious about the symbolism of a mole on your head, it depends on its placement: a mole on the right side of your head will set you up for career success, per Onmanorama, and one on your left may ensure you'll always be traveling (but you'll be strapped for cash).
