average cost of radiation treatments
1 For patients not covered by health insurance, radiation therapy can cost $10,000-$50,000 or more, depending on the type of cancer, number of treatments needed and especially the type of radiation used. An article published by the American College of Radiology states that the cost to treat prostate cancer with proton therapy radiation can reach $40,000. 2  Stereotactic radiosurgery, which often is used for brain tumors or tumors that have been deemed inoperable, can cost up to $55,000 or more.
