What type of radiation is used to treat cancer?
Internal radiation: Internal radiation is also called brachytherapy. A radioactive source is put inside the body into or near the tumor. Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body.
How does radiation therapy kill cancer cells?
How Radiation Therapy Works Against Cancer At high doses, radiation therapy kills cancer cells or slows their growth by damaging their DNA. Cancer cells whose DNA is damaged beyond repair stop dividing or die. When the damaged cells die, they are broken down and removed by the body.
Do electromagnetic fields produced by power lines cause cancer?
There was no evidence that electrical utility workers who were exposed to pulsed electromagnetic fields produced by power lines were more likely to develop brain tumors or leukemia than the general population (54).
What is the most common treatment for cancer?
Radiation is one of the most common treatments for cancer. Other names for radiation treatment are radiation therapy, radiotherapy, irradiation, or x-ray therapy. Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells.
Which element is used in treatment of cancer?

Which element is used in radiotherapy for cancer treatment?
The radioactive element radium “looks like a calcium molecule, so it gets incorporated into areas of the body where bone turnover is highest,” such as areas where cancer is growing, Dr. Kunos explained. The radium is then able to kill nearby cancer cells.
Is cobalt -60 used to treat cancer?
Cobalt 60 (60Co) is often the ideal mode of radiation for treating laryngeal cancer.
How is Gamma rays used to treat cancer?
Use and importance in clinical medicine Gamma rays can kill living cells and damage malignant tumor. The Gamma radiation intensity decreases exponentially with the depth of penetration. They damage the cancerous cells' DNA, causing them to die or reproduce more slowly.
What is ATP in cancer?
Adenosine triphosphate (ATP) is one of the main biochemical components of the tumor microenvironment (TME), where it can promote tumor progression or tumor suppression depending on its concentration and on the specific ecto-nucleotidases and receptors expressed by immune and cancer cells.

Solution : Radium being radioactive is used in the cancer treatment.
Why is cobalt-60 used to treat cancer?
The cobalt-60 system is designed to deliver radiation in the shape of a sphere. To cover irregularly shaped tumors, several of these radiation spheres are combined to best mimic the tumor's shape.
How is cobalt-60 used for cancer?
Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer. Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue.

What do expert organizations conclude about the cancer risk from EMFs?
The Working Group classified ELF-EMFs as “possibly carcinogenic to humans,” based on limited evidence from human studies in relation to childhood leukemia. Static electric and magnetic fields and extremely low frequency electric fields were determined “not classifiable as to their carcinogenicity to humans” ( 12 ).
What have studies shown about possible associations between non-ionizing EMFs and cancer in children?
Numerous epidemiologic studies and comprehensive reviews of the scientific literature have evaluated possible associations between exposure to non-ionizing EMFs and risk of cancer in children ( 12 – 14 ). (Magnetic fields are the component of non-ionizing EMFs that are usually studied in relation to their possible health effects.) Most of the research has focused on leukemia and brain tumors, the two most common cancers in children. Studies have examined associations of these cancers with living near power lines, with magnetic fields in the home, and with exposure of parents to high levels of magnetic fields in the workplace. No consistent evidence for an association between any source of non-ionizing EMF and cancer has been found.

The National Institute of Environmental Health Sciences (NIEHS) website has information about EMFs and cancer.
What are the risks of ELF radiation?
Most of the results were based on participants’ job titles and not on actual measurements of their exposures. More recent studies, including some that considered exposure measurements as well as job titles, have generally not shown an increasing risk of leukemia, brain tumors, or female breast cancer with increasing exposure to magnetic fields at work ( 45 – 50 ).
Can non-ionizing EMFs cause cancer?
Although there is no known mechanism by which non-ionizing EMFs could damage DNA and cause cancer , even a small increase in risk would be of clinical importance given how widespread exposure to these fields is.
Can ELF cause cancer?
No mechanism by which ELF-EMFs or radiofrequency radiation could cause cancer has been identified. Unlike high-energy (ionizing) radiation, EMFs in the non-ionizing part of the electromagnetic spectrum cannot damage DNA or cells directly. Some scientists have speculated that ELF-EMFs could cause cancer through other mechanisms, such as by reducing levels of the hormone melatonin. There is some evidence that melatonin may suppress the development of certain tumors.
How does radiation help cancer?
When radiation is combined with surgery, it can be given: 1 Before surgery, to shrink the size of the cancer so it can be removed by surgery and be less likely to return. 2 During surgery, so that it goes straight to the cancer without passing through the skin. Radiation therapy used this way is called intraoperative radiation. With this technique, doctors can more easily protect nearby normal tissues from radiation. 3 After surgery to kill any cancer cells that remain.
