Can a mole on the back be cancerous?

Hello,

Welcome to icliniq.com.

Thank you for the query. I have seen the picture (attachment removed to protect the patient’s identity) and as per my experience, only two skin diseases look like this. The first one is of course melanoma and the second is seborrheic keratosis. The main signs and symptoms of melanoma are as follows:

With time the size will increase. The color changes with time. The margin of the lesion also changes from round to irregular. As the melanoma goes deep bleeding can also increase. It appears as a single lesion most of the time. It is true that white people are more prone to get melanoma, but your site of lesion is not common. At this age, melanoma or other skin cancer comes over more photo-exposed parts of the body like the face or hand.

Now, let me explain the signs and symptoms of seborrheic keratosis. They are more common over the scalp and in older age groups. They do not bleed and are a little raised (not flat) on the skin. Often found multiple in number. They are not itchy and have no specific symptoms. Now, I personally feel your problem goes more toward melanoma or BCC (basal cell carcinoma). You need to go for a biopsy. A biopsy would be the ultimate tool to diagnose the disease.

Thank you.
