Common risks associated with a prostate biopsy include:

  • Infection. The most common risk associated with a prostate biopsy is infection. Rarely, men who have a prostate biopsy develop an infection of the urinary tract or prostate that requires treatment with antibiotics.
  • Bleeding at the biopsy site. Rectal bleeding is common after a prostate biopsy. Don't start taking any blood-thinning medications after your biopsy until your doctor says it's OK.
  • 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.
  • Difficulty urinating. In some men, prostate biopsy can cause difficulty passing urine after the procedure. Rarely, a temporary urinary catheter must be inserted.
