Can skin cancers occur on the scalp?
Yes, absolutely. Melanoma type skin cancers can occur on any part of the body which has pigment-producing cells (melanocytes), and that includes the skin of the scalp.
Should I be worried about a mole on the scalp?
If you have recently noticed a mole on your scalp or think that an existing mole may have changed, you should get a skin check as soon as possible to make sure it is not A Melanoma – a very dangerous type of skin cancer. Scalp melanomas have been shown to be more lethal than other melanomas, with one study showing scalp and neck melanomas deaths were nearly twice as common compared to melanomas elsewhere on the body.
Why are scalp melanoma skin cancers more dangerous?
The most common reason is due to a delay in diagnosis, unless you are consciously trying to look for them.
Some also believe that the scalp provides the right conditions for the melanoma to spread, since it has abundant blood vessels and lymphatics.
Can other skin cancers occur on the scalp?
Yes, other skin cancers such as Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) can occur on the scalp.
