In terms of the Electromagnetic spectrum, Gamma radiation and X-rays are usually used to treat cancer patients in a process called Radiotherapy, as these are the highest energy forms of the EM spectrum. However, other forms of radiation such as high-energy neutrons are being used, which do not belong to the EM spectrum.
Samarium doesn't kill cancer cells. A radioactive isotope of samarium (samarium-153) is used in a chemotherapy agent, but it's the radiation, not the samarium, that kills the cancer cells.
in radiotherapy, to kill cancer cells
Ionizing radiation, such as X-rays and gamma rays, are used in radiation therapy to kill cancer cells. These high-energy electromagnetic waves can damage the DNA within cancer cells, preventing them from dividing and growing.
One use of gamma rays is in cancer treatment, where they can be directed at cancer cells to destroy them.
1. Radium was used in the past for the radiotherapy of some cancers. 2. But because radium is strongly radioactive uncontrolled irradiation or contamination with radium can lead to some cancers.
Treatment can be a combination of surgery, medications used to kill cancer cells (chemotherapy ), and x rays or other high energy rays used to kill cancer cells (radiation therapy)
Most drugs used to treat cancer kill actively growing/replicating cells.
The medication Lipisol is used as a chemotherapy drug. Lipisol is a capsule a cancer patient swallows that slowly works to kill the cancer cells in the body.
Radiation has the capacity to kill cells, both cancer cells and normal cells, but cancer cells are less healthy than normal cells, and they are more easily killed, so radiation can kill cancer cells while not killing the patient (although the patient will suffer side effects). Doctors are always looking for what is known as the "magic bullet" which is something that kills only cancer cells but does not harm normal cells; so far we have not found it. If we do invent a magic bullet, than radiation treatments will no longer be used.
A chemotherapeutic drug used to treat cancer must be more toxic to cancer cells (at least, to the cancer cells of the specific type of cancer which it is intended to treat) than it is to the healthy cells of the body. Otherwise, you could only kill the cancer by also killing the patient.
Gamma rays can cause cancer by damaging the DNA within cells, leading to uncontrolled growth. In cancer treatment, gamma rays are used in radiation therapy to target and kill cancer cells. The high-energy radiation helps to destroy cancer cells and shrink tumors.
