The diagnosis of prostate cancer can be confirmed only by a biopsy. During a biopsy, a urologist (a doctor who specializes in diseases of urinary and sex organs in men, and urinary organs in women) removes tissue samples, usually with a needle. This is generally done in the doctor's office with local anesthesia. Then a pathologist (a doctor who identifies diseases by studying tissues under a microscope) checks for cancer cells.A blood test called a PSA (prostate-specific Antigen) is used to measure the level of PSA in the blood.An elevated PSA level can indicate either an enlarged prostate or prostate cancer. If PSA levels are high, a biopsy of the prostate can be done to confirm the presence of prostate cancer.
Yes, transrectal electroejaculation is very painful and is usually done under analgetics or anesthesia.
It means that there is a lesion which will be biopsied under direct guidance with imaging using MR scanner. A needle is guided with the help of the MR scanner to locate the lesion and biopsies are taken
Prior to the biopsy, the patient is placed under general anesthesia
The medical term for examination of tissue under a microscope is called- Histology
An excisional biopsy itself usually takes under one hour
A PET scan can reveal the presence of a mass, but it is also good to have a sample of cells from the suspected area to look for changes in the nucleus to ascertain whether pre-cancerous changes are taking place. Hence, the biopsy under CT guidance.

the usual test is a blood test called a PSA test. this measures the amount of a hormone in the blood. higher PSA means a larger prostate. A high PSA is not necessarily an indicator of prostate cancers (PCa). A rapidly changing PSA is an indication of PCa. Once suspects the usual test is to do a biopsy of the prostate. The prostate is located under the bladder and right next to the rectum. To take a biopsy - a tool is inserted in the rectum and a needle punches through the rectum wall into the prostate to take a core sample. 6 to 12 samples are usually taken. After the biopsy, there is some pain- but be aware you will see blood in your urine and in your semen. I didn't know this and it scared the beejesus out of me and my wife.
Biopsy is removal of tissue for examination under a microscope.
If the changes seen under the microscope don't point to any particular diagnosis, the biopsy result will be nonspecific.
