Hello, i have an oddly shaped mole on my thigh. This mole has always been there but im not sure whether it was darker in the middle before. It is about 5,5mm big and not thick, however unsimmetrical and quite a weird shape. Its brown but darker in the middle. My appointment to a dermatologist is in 3 weeks. Im scared that this is melanoma and that it will spread faster than i can go to my derm. Please help me get through this, tell me if this is normal or not.
