What Does Low White Blood Cell Count Mean? – Leukopenia

Radiation

Radiation

If you ever heard that a cancer patient received radiotherapy or radiation and wondered why? it is because ionizing radiation is lethal to cells. That’s why we limit the amount of radiation we expose patients to. This includes X-rays and CT scans. Radiation has an especially harmful effect on rapidly dividing cells, including hair cells, nails, skin, testes, ovaries and blood cells. That’s why leukopenia is a common finding in cancer patients exposed to radiation therapy or even in case of radiation sickness. A stark example of this was seen in survivors of the bombing of Hiroshima and Nagasaki, and those who lived in the vicinity of the Chernobyl reactor.
