Just diagnosed with prostate cancer. I am 68 very fit, still working and enjoying it. I had no prostate symptoms. I went to the doctor's with what I suspected was bowel problem and blood test showed high PSA 7.2. MRI showed a lesion 13mm then biopsy and rated 3+4 ?? The advice given is leave it 3 months then new blood test and if higher another MRI and biopsy then possible operation to remove? Bowel problem turned out to be Metformin reaction. Is it ok to leave it 3 months?
