Later they chose to decrease it back again due to (exposure to healthy tissues).in 1965 doctors report the success of therapy (y90) to treat inoperable liver cancer when there was no cure for it. In the early1970s doctors believed that they had to increase the use of radioactive “seeds” knowing that it can mark prostate and other types of cancer.in 1977 a new therapy called lumpectomy and the removal of only the tumor is effective as mastectomy for women with early stages breast cancer. In 1975- 1980, doctors prove that the radiation therapy is a main part in treating glioblastoma where it adds survival mode from 3-9 months based on studies, and this was the first therapy to treat brain cancer. In 1981 when adding a drug called 5-fluorouracil id adds up the chances of survival for one year 10 to 40 %. In 1980s they discover gamma knives that can treat certain brain tumors. In the early 90s when computers and electronics were involved in hospitals they used the therapy in making 3d plans. In the late 90s doctors introduce a new radioactive therapy called (IMRT) which can remove large tumors that lie close to vital organs and other sensitive tissue. In 1999 scientists prove that ideational therapy cuts the risk that small cell lung cancer will extent to the brain.in 2001 doctors that when giving a high-dose of radiation it helps the men with avoiding cancer recur.
