By Desiree Fisch What is Radiation Therapy History of Radiation Therapy...
What Breakthroughs Were Made Achievements
New Methods What Might Be Wrong With Radiation Therapy? "About half of all cancer cases, radiation therapy is used." No one knows for sure exactly who invented radiation therapy, but we know of the many breakthroughs Different types and forms: "At the beginning of the 20th century...it was discovered that it could cause cancer as well as cure it." Why is Radiation Therapy so Important? Radiation Therapy And how it has revolutionized cancer Thesis: Radiation therapy has revolutionized the treatment of cancer by offering a variety of ways to eradicate the disease. Radiation therapy uses high energy, penetrating waves or particles to destroy cancer cells and keep them from reproducing. Fun fact: radiation therapy can also be called radiotherapy, x-ray therapy radiation treatment, cobalt therapy, electron beam therapy, or irradiation Radiation therapy can occur from a source outside of the body. Such as-- Computed Tomography Scanner Magnetic resonance imaging Positron Emission Tomography or can occur from inside the body, such as implants or surgeries. How Was it Discovered? "In 1896, a German physics professor, Wilhelm Conrad Roentgen, presented a remarkable lecture entitled 'Concerning a New Kind of Ray.' Roentgen called it the 'X-ray', with 'x' being the algebraic symbol for an unknown quantity... Within months, systems were being devised to use x-rays for diagnosis, and within 3 years, radiation was used in to treat cancer." In 1901, Roentgen discovered that it began with radium and low-voltage machines. That same year in France, "it was discovered that daily doses of radiation over several weeks greatly improved the patient's chance for a cure." CRT (Conformal Radiation Therapy) uses CT images and special computers to very precisely map the location of a cancer in 3 dimensions. CPBRT (Conformal Proton Beam Radiation Therapy) "uses a similar approach to focusing radiation on the cancer. But instead of using x-rays, this technique uses proton beams." IORT (Intraoperative Radiation Therapy) is a form of radiation therapy that delivers the treatment at the time of a surgery. It is more commonly used in abdominal or pelvic cancers and in cancers that tend to recur. "It was no wonder they [were diagnosed] with leukemia." Also, radiation therapy can kill normal cells as well as cancer cells. Some side effects are:
-skin changes
-appetite loss
-hair loss
most side effects depend on the area of treatment Radiation therapy may have side effects, but it has been stated by the American Cancer Society, "Most side effects go away in time." and it is stated by the medical dictionary, "the benefits almost always exceed the risks." Considering that many forms of treatment grow from radiation therapy, it is highly important. one of the few root cancer treatments, it is used in combination with another method in several cases, making it one of the most primary forms of treatment. How Has Radiation Therapy Revolutionized Cancer Treatments? -given new ways to eliminate the disease
-is the root of several treatment methods
-caused many breakthroughs in cancer research to spring forward The End
