i have freckles all over my face.
[{"role": "system", "content": "Freckles are clusters of concentrated melaninized cells which are most easily visible on people with a fair complexion. Freckles do not have an increased number of the melanin-producing cells, or melanocytes, but instead have melanocytes that overproduce melanin granules (melanosomes) changing the coloration of the outer skin cells (keratinocytes). As such, freckles are different from lentigines and moles. The formation of freckles is triggered by exposure to sunlight. The exposure to UV-B radiation activates melanocytes to increase melanin production, which can cause freckles to become darker and more visible. This means that one may have never developed freckles before, but after extended exposure to sunlight, they may suddenly appear. Freckles are predominantly found on the face, although they may appear on any skin exposed to the sun, such as arms or shoulders. Heavily distributed concentrations of melanin may cause freckles to multiply and cover an entire area of skin, such as the face. Freckles are rare on infants, and more commonly found on children before puberty. Upon exposure to the sun, freckles will reappear if they have been altered with creams or lasers and not protected from the sun, but do fade with age in some cases.\n"}, {"role": "assistant", "content": "I have a freckle on my face, it is a concentrated melanizred cell.

I guess if you are concerned you can have a biopsy done."}, {"role": "assistant", "content": "Thanks for the info.  I guess a melanized cell from a freckle and a melanoma, or cancerous cell, may be two different things even though they sound alike."}, {"role": "user", "content": "Yeah, I think the bigger it is the more concern there is. Many people with moles and freckles have nothing to worry about it."}, {"role": "assistant", "content": "But i have heard that freckles and melanomas do both occur in people with a very light skin pigmentation, so perhaps there is something there.  That is a question for MENSA, i suppose."}, {"role": "user", "content": "Well I would talk to a dermatologist about it.
