Risks associated with a prostate biopsy include:
- Bleeding at the biopsy site. Rectal bleeding is common after a prostate biopsy.
- Blood in your semen. It's common to notice red or rust coloring in your semen after a prostate biopsy. This indicates blood, and it's not a cause for concern. Blood in your semen may persist for a few weeks after the biopsy.
- Blood in your urine. This bleeding is usually minor.
- Difficulty urinating. In some men, prostate biopsy can cause difficulty urinating after the procedure. Rarely, a temporary urinary catheter must be inserted.
- Infection. Rarely, men who have a prostate biopsy develop an infection of the urinary tract or prostate that requires treatment with antibiotics.
