It depends on your insurance plan. Many plans allow scheduling directly with a radiation oncology department once osteoarthritis is documented; others require a referral from your primary care doctor, orthopedist, or rheumatologist first. Call the office above to ask what they require.

A typical LDRT course uses a low total dose delivered over six treatments, substantially less than the dose used in cancer treatment. Long-term clinical experience hasn't identified a clear signal of increased radiation-related cancer risk after LDRT for osteoarthritis, though studies aren't large enough to rule out a very small risk entirely. The radiation oncologist above can walk through how the benefit and risk apply to your specific case.

A consultation, then a CT planning scan, then typically six treatment sessions given two to three times a week over two to three weeks. Each session takes roughly 10 to 15 minutes, mostly positioning; there's no needle, sedation, or recovery time.
