Was originally tested 2/16/18 with PSA of 150. Uro recommended 2nd opinion testing. Tested 2nd time on 2/22/18, PSA jumped to 262. Uro recommended a biopsy. Friends who had prostate cancer said do MRI, others said CT Scan. Have an appointment with a specialist on 3/3/18. Can I do all of the above? Waiting for 1 after another test may make it worse since PSA jumped drastically in 6 days. HELP!
