Curie made a special trip to see Dr. Failla also pioneered the use of gold rather than glass tubing to capture the radon gas. Gold had the advantage of filtering out the beta rays that can cause skin burns and inflammation, while still allowing the more powerful gamma rays to pass through. Seed implantation is still a mainstay of cancer brachytherapy today.
Failla also had the foresight to hire a talented young physicist named Edith Quimby as his assistant. Quimby would go on to develop standard dosing tables for radiation treatment and also developed the radiation film badge as a safety protection against accidental exposure. We now know that radiation works by damaging DNA in cells. Cancer cells are less able to repair this DNA damage than normal cells and die preferentially as a result.
Before its mechanism of action was understood, those who handled radium did not know to take appropriate safety precautions and suffered serious consequences as a result. Marie Curie died in of aplastic anemia, a blood disease likely caused by chronic, low-level radiation exposure.
James Douglas — who believed radium could cure many ailments and kept a pitcher of radium water on his desk — died in of a similar disorder. The most famous cautionary tale was the case of the radium dial painters. Between and , the US Radium Corporation in Orange, New Jersey, produced watches with luminescent dials coated with glow-in-the-dark paint incorporating radium.
Over the course of months and years, the women became sick, some developing disfiguring bone cancers. The radium in the paint behaved like calcium and accumulated in bones. A linear accelerator, or special machines such as the Gamma Knife or CyberKnife, can be used to deliver this treatment. Intraoperative radiation therapy IORT is a form of treatment that delivers radiation at the time of surgery. The radiation can be given directly to the cancer or to the nearby tissues after the cancer has been removed.
Chemical modifiers or radiosensitizers are substances that make cancer more sensitive to radiation. The goal of research into these types of substances is to develop agents that will make the tumor more sensitive without affecting normal tissues. Researchers are also looking for substances that may help protect normal cells from radiation. The American Cancer Society medical and editorial content team.

Timeline: Milestones in Cancer Treatment. The former includes the technological transition process from the initial technique applied to the first model to the latest technique currently used in a variety of machines.
The latter has had a direct effect on treatment outcomes and safety, which changed the paradigm of radiation therapy, leading to new guidelines on dose prescriptions, innovation of dose verification tools, new measurement methods and calculation systems for radiation doses, changes in the criteria for errors, and medical law changes in all countries.
Various complex developments are covered in this review. To the best of our knowledge, there have been few reviews on this topic and we consider it very meaningful to provide a review in the festschrift in celebration of the 30th anniversary of the KSMP.
Introduction Other Sections Abstract Introduction Summary Conflicts of Interest Availability of Data and Materials Author Contributions Reference History is like a mirror that can be used to guide evaluation of the present and it can illuminate the future through reflection on the past. Changes in radiation therapy 1 Discovery of X-rays and the beginning of radiation therapy Radiotherapy can be traced back about years to the discovery of X-rays by a Germany physicist named W.
Birth of radiation cancer therapy devices and development of high energy devices 1 Initial model of radiation cancer therapy devices Current cancer therapy includes radiotherapy using an X-ray beam. The developmental process of kV therapy machines from Granz to Orthovoltage. Initial design of the electron acceleration mode. Electrons were drifted through a series of flight tubes connected to an alternating voltage supply AC and accelerated only as they passed through the gaps between the drift tubes.
