When it comes to radiation and cancer risk, it is often x-rays and gamma rays that people think about. Learn what we know about these types of high-energy radiation and how they affect cancer risk. Radon is a colorless, odorless, radioactive gas. Long-term exposure to radon can lead to lung cancer. Find out more about radon and its effects here.

These rays, as well as some higher energy ultraviolet (UV) rays, are forms of ionizing radiation, which means they have enough energy to remove an electron from (ionize) an atom. This can damage the DNA (genes) inside of cells, which can sometimes lead to cancer. What is radiofrequency (RF) radiation?

Radiation therapy is one of the most common treatments for cancer. More than half of people with cancer get radiation as part of their care. It might be called radiotherapy, irradiation, x-ray therapy, radiation treatment, or sometimes just radiation. It works by using high-energy rays, like x-rays, to destroy or damage cancer cells.

Because ionizing radiation is a carcinogen linked to cancer development, its use in medical practice must be balanced against the associated health risks. While most previous studies have examined cancer-associated mortality risk among people who have been exposed to high levels of radiation, there is little information on this risk for people ...

2016年5月27日 · The U.S. National Toxicology Program (NTP) has released partial results from an animal study of the effect of radiofrequency radiation associated with cell phones. The group found radiofrequency radiation was linked to a higher risk of two cancers. Below is a response from Otis W. Brawley, M.D., American Cancer Society Chief Medical Officer.

For the purposes of this fact sheet, the word radiation refers to ionizing radiation; the most common forms of radiation in medicine are x rays and gamma rays. Exams and procedures that use radiation are necessary for accurate diagnosis of disease and injury.

2017年12月15日 · Photons and neutrons are indirectly ionizing: when absorbed in tissue, they give up their energy to produce fast-moving charged particles that then inflict damage. The four principles of radiobiology are repair, repopulation, reassortment, and reoxygenation.

2015年11月9日 · The types of cancer that may be associated with radiation exposure are listed by the American Cancer Society which states: "Much of what we know about cancer risks from radiation is based on studies of the survivors of the atomic bombs in Nagasaki and Hiroshima. These people had higher risks of some, but not all cancers.

2024年2月19日 · Ionizing radiation is a powerful form of energy with medical applications such as diagnostic testing. At high enough doses, it can alter your body's cells and DNA. Unlike some non-ionizing radiation, it can cause serious harm or cancer with enough exposure. Radiation exists all around us and is in two forms: ionizing and non-ionizing radiation.
