I have a mole i've always had.i thought it had got bigger went to my gp who said it was fine,don't worry. could it be melanoma?its beige, 1colour.

See dermatologist: There are 4 reasons to remove a skin mole. First, the possibility of cancerous change occurring in a mole sometime in the future (a pre-cancerous active junctional mole); second, a suspected cancerous change already present, and removal is diagnostic and therapeutic; third, cosmetic reasons; fourth, functional and anatomical changes occurring in a mole. See a dermatologist for assurance

Observe vs remove: Any suspicious mole should be biopsied and/or removed. The risks of excision are generally outweighed by the risk of missing a malignant lesion. Melanoma is usually dark in pigment with irregular shape and borders. However, some malignancies may appear completely benign, and the diagnosis can only be made by removal and examination under the microscope.

Changing moles: demand close follow-up. In general, melanoma usually have irregular shapes, borders and pigmentation and are usually growing. These are generalizations. Bottom line, any lesion that bleeds on its own, goes through cycles of healing and breakdown, or shows rapid progression demand a biopsy or even excision. You can follow your mole with digital photography and a ruler.
