What is the purpose of a bone biopsy?
There are several different types of biopsies.A needle (percutaneous) biopsy removes tissue using a hollow tube called a syringe. A needle is passed through the syringe into the area being examined. The surgeon uses the needle to remove the tissue sample. Needle biopsies are often done using x-rays (usually CT scan), which guide the surgeon to the appropriate area. An open biopsy is a surgery that uses general anesthesia. This means you are asleep and pain-free during the procedure. The procedure is done in a hospital operating room. A surgeon makes a cut into the affected area, and the tissue is removed. Closed biopsy uses a much smaller surgical cut than open biopsy. A small cut is made so that a camera-like instrument can be inserted. This instrument helps guide the surgeon to the appropriate place to take the sample. A biopsy are most often done to examine tissue for disease. A biopsy may also be done to match organ tissue before a transplant. http://www.nlm.nih.gov/medlineplus/ency/article/003416.htm http://en.wikipedia.org/wiki/Biopsy

Digital Rectal exam; blood test for PSA level; transrectal biopsy. Only the biopsy can tell for sure if cancer is present. And it is not 100% accurate as the biopsy needle may miss the cancer on the first sampling. The test may need to be done again a few months down the road.
