I was asked by the medical insurance company about the urologist tests three years ago regarding to my slight PSA increase. 

Here is my reply:

"I have just received the request for my urologist test (related to PSA raise) in 2013... However, it has been such a long time and I don't have any other information except that I remember i was referred to Sheffield Teaching Hospital relevant department.

I took quite a few tests and at last the doctor told me that everything seems fine (he could not identify what reasons causes the raise despite the outcome of a MRI test and quite a few blood tests), He suspects that there is just a minor infection. He prescribed me with 6 weeks of strong antibotics but I didn't take them (because I think 6 week antibotics will itself kill myself after the pharmacy told me that they are very strong and normally are given to people who have a very serious infection).

After 3 years, I forget about this and I believe there is nothing wrong with me."
