What are examples of cancer in radiation induced malignancies?

Risk of Development of RIM

Radiotherapy for primary disease RIM Relative risk of development of RIM
Breast [46] Esophageal cancer 2.19 at 15+ years of radiotherapy
Lung cancer 1.62 at 10 – 14 years 1.49 at ≥ 15 years
Myeloid leukemia 2.99 at 1 – 5 years
Second breast cancer 1.34 at 5 – 10 years 1.26 at 15+ years

Which is the most common radiation induced cancer in humans?

The breast seems to be one of the most susceptible organs for radiation induced cancer, but the A-bomb cohorts indicate a risk only in the younger age group (< 40 y at exposure). Except for the breast, the thyroid is the most susceptible organ in humans for radiation induced solid tumors.

What kind of malignancy can occur as a consequence of radiation therapy?

One possible late effect is the development of a second cancer. This is a new type of cancer that develops because of the original cancer treatment. The risk of this late effect is low. And the risk is often smaller than the benefit of treating the first cancer.

How long does radiation induced cancer take?

Radiation can cause cancer in most parts of the body, in all animals, and at any age, although radiation-induced solid tumors usually take 10–15 years, and can take up to 40 years, to become clinically manifest, and radiation-induced leukemias typically require 2–9 years to appear.

Can radiation cause cancer later in life?

There is also a risk for other cancers, which are mostly solid tumors, after having radiation therapy. Most of these cancers develop 10 years or more after radiation therapy.

What are the chances of getting cancer from radiation?

The risk of developing cancer from a lifetime exposure of background radiation is about 1 in 100, or 1% of the population.10It is impossible to avoid all background radiation, but the best ways to limit unnecessary exposure to radiation from the environment is to prevent your exposure to radon and repeated unprotected …
