What is the difference between conventional radiation therapy and stereotatic radiosurgery?
Conventional radiation therapy (radiotherapy) administers a broad beam of radiation from one to two directions in 30 to 45 treatments. It delivers low-dose beams of radiation over a period of 6 to 8 weeks - the time required to allow healthy tissue damaged during treatment to recover.
CyberKnife radiosurgery delivers high-dose beams of radiation - which can be more effective in killing tumors anywhere in the body. This system can deliver radiation beams from virtually unlimited directions with sub-millimeter accuracy. With radiosurgery, damage to surrounding healthy tissue is minimized; therefore the treatment can be completed typically in one to five days.
