Hi
Whenever any new moles develop, or there is any change in the color or size or bleeding in an existing mole, it may indicate some precancerous changes. However, many a times moles develop due to changes in skin pigmentation and do not have any clinical significance. Presence of hair does not hold much significance in prognosis.
Melanoma is the most serious type of skin cancer which can spread to several parts of the body. Melanoma occurs due to changes in the melanin-producing cells (melanocytes) of skin. Excessive exposure to ultraviolet (UV) radiation and presence of a family history is a leading factor in the development of melanoma. If any abnormal cells are seen, the entire mole and a margin of normal tissue around it need to be removed. Usually once a mole has been removed, chances of recurrence are minimal.
I suggest it is better to seek a dermatologist opinion.
Take care
