Dermatology Questions? Ask an Online Dermatologist.
Thank you for your question. My name is***** and I will do my best to provide a useful input.
Would a photograph of the affected area be possible at your convenience?
Apologies did not get an alert that you had responded. Taking a look at the picture now - will get back to you shortly.
Thank you for the photograph. This mole shows varied pigmentation with lighter brown pigmentation extending out from the margins - this is significant given your history of sunburns and tanning bed use as well as your family history of skin cancer. The dermatologist tomorrow will most likely look at this mole with an instrument called a dermatoscope and then if that shows unusual mole features the mole will probably be biopsied. This will prove conclusively whether it is harmful or not.
As for weight gain causing changes in moles - this does not usually occur unless the weight gain is due to a hormonal cause such as oral contraceptive use since these hormones can cause enlargement of benign moles.
Please feel free to ask if you have any queries.
