Effects on cell DNA: Any form of radiation ( ionization energy ) effects on cell , allows dna break down , prevent normal repair mechanisms of cell
Dr. Devon Webster
Medical Oncology 22 years experience
It breaks your DNA: Radiation exposure can directly damage dna inside cells, which is where the genetic instructions for a cell reside. This damage can cause cells to grow uncontrollably. We are all exposed to some amount of radiation every day from the sun and the environment. However, medical imaging tests like ct scans are a big source of additional radiation exposure. Be aware of this!

A 35-year-old member asked:

What cancers are proven to be developed by radiation exposure?

Here's for starters: In atom bomb survivors, all the common leukemias except chronic lymphocytic leukemia ended up being increased. Breast and salivary gland cancer also had some increase. Following therapeutic radiation, there's more of a risk of sarcomas since unlike chemicals, radiation doesn't spare their cells of origin. Lately increased colorectal cancer's been shown after prostate radiation. Hope this helps.

Are radiologists likely to get cancer because of their exposure to radiation?

No!: They might, if they didn't protect themselves. But they go behind leaded glass, they wear lead aprons, and they stay in their offices while other people take the x-rays (who also protect themselves). No risk whatsoever.

How can radiation both cause and heal cancer?

Exposure vs directed: Exposure of whole body to large amounts of radiation or chronic low amounts of radiation can induce mutations in normal cells that cause mutations to allow cancer to develop. After exposure cancer development takes years. Some organs tolerate more radiation than others. Focused high dose radiation can induce lethal mutations in cancer cells while minimizing exposure to normal cells.

Very unlikely: There is no objective evidence that radiation from phones causes cancer.
A 21-year-old member asked:

Is radiation a cause of cancer?

Yes: Environmental exposure (as in hiroshima, chernobyl) can lead to blood and thyroid cancer decades later. Occasionally, radiation used for treatments or frequent scanning (x-rays, ct scans) can lead to cancer later in life.
