2. Radiation-induced cancer - Wikipedia

   en.wikipedia.org/wiki/Radiation-induced_cancer

   Radiation hormesis is the conjecture that a low level of ionizing radiation (i.e., near the level of Earth's natural background radiation) helps "immunize" cells against DNA damage from other causes (such as free radicals or larger doses of ionizing radiation), and decreases the risk of cancer. The theory proposes that such low levels activate ...

3. Biological effects of radiation on the epigenome - Wikipedia

   en.wikipedia.org/wiki/Biological_effects_of...

   Due to its ability to induce cell cycle arrest, ionizing radiation is used on abnormal growths in the human body such as cancer cells, in radiation therapy. Most cancer cells are fully treated with some type of radiotherapy, however some cells such as stem cell cancer cells show a reoccurrence when treated by this type of therapy. [1]

4. Acute radiation syndrome - Wikipedia

   en.wikipedia.org/wiki/Acute_radiation_syndrome

   Exposure to high doses of radiation causes DNA damage, later creating serious and even lethal chromosomal aberrations if left unrepaired. Ionizing radiation can produce reactive oxygen species, and does directly damage cells by causing localized ionization events. The former is very damaging to DNA, while the latter events create clusters of ...

5. Radiation therapy - Wikipedia

   en.wikipedia.org/wiki/Radiation_therapy

   Radiation therapy or radiotherapy (RT, RTx, or XRT) is a treatment using ionizing radiation, generally provided as part of cancer therapy to either kill or control the growth of malignant cells. It is normally delivered by a linear particle accelerator .

   Radiation, which kills cancer cells and shrinks tumors, can, unfortunately, raise the risk of developing leukemia and breast, lung and pancreatic cancer, according to the American Cancer Society.

7. Free radical damage to DNA - Wikipedia

   en.wikipedia.org/wiki/Free_radical_damage_to_DNA

   Cells have developed complex and efficient repair mechanisms to fix the lesions. In the case of free radical attack on DNA, base-excision repair is the repair mechanism used. Hydroxyl radical reactions with the deoxyribose sugar backbone are initiated by hydrogen abstraction from a deoxyribose carbon, and the predominant consequence is eventual ...
