[|Human|] Hi, about two weeks ago I had a health checkup where I noticed a brown spot on my knee that had suddenly appeared next to a black mole that appeared a few years ago. I had the old mole checked up before and was told it was benign. Anyway it concerned me so I asked the doctor to take a look. He didn t make mucChatDoctorments on it but wrote me a referral to a specialist and suggest I get a biopsy there. I ve tried scratching at the brown spot and scrubbing at it. It s definitely not dirt or anything as it did not budge at all but I just looked at it and it has disappeared leaving a slight bump. Should I be concerned about this? I have not seen the specialist yet but would like not to if it isn t anything serious.
[|AI|]  Hello! Thank you for the query. No doctor is able to tell if the mole is benign or malignant without removing it and sending for histopathology. Dermatologist is able to establish if the mole is in high risk of melanoma malignum. It can be done with dermatoscope. But the final diagnose can be set only when you do remove it and check for cancer cells under the microscope. If the mole changes its size, color, gets painful, redness appears around, gets more prominent, the verges are uneven, the mole is suspicious and should be removed. Otherwise, it should be left alone. Hope this will help. Regards.
