<s>[INST] Hi doctor, About a month ago I vigorously scratched off a mole that was on my back. While lifting weight and lying on my back, it got irritated. I have had the mole for at least seven years. It has always been relatively big and light brown shade. However, when I picked it off it went away at first, then about a month later it has gradually started to come back. Now, it is not even, looks irregular and varied in color a little bit. It has also grown a hair in it. In interner, I searched pictures of melanoma and freaked out. I do not have a history of skin cancer in my family. I am 24 years old and I go to the beach and pool quite often. I have not always worn sunscreen, but most of the time I wear SPF 15. I am not on any medication. [/INST] Hi.
