Radiation-induced cancer
Radiation-induced cancer
Radiation-induced cancer (pronunciation: /ˌreɪdiːˈeɪʃən ɪnˈdjuːst ˈkænsər/) is a form of cancer that is caused by exposure to radiation.
Etymology
The term "radiation-induced cancer" is derived from the English words "radiation", which refers to the emission of energy as electromagnetic waves or as moving subatomic particles, "induced", which means brought about or caused, and "cancer", which is a disease caused by an uncontrolled division of abnormal cells in a part of the body.
Definition
Radiation-induced cancer is a type of cancer that develops following exposure to ionizing radiation. This can occur as a result of exposure to natural sources of radiation, such as radon gas, or artificial sources, such as radiation therapy for cancer treatment.
Types
There are several types of radiation-induced cancers, including leukemia, thyroid cancer, lung cancer, breast cancer, and skin cancer. The type of cancer that develops depends on the area of the body that was exposed to radiation.
Causes
Radiation-induced cancer is caused by damage to the DNA within cells, which can occur when the cells are exposed to ionizing radiation. This can cause the cells to grow and divide uncontrollably, leading to the development of a tumor.
