This can lead to cancer. It’s the secondary cancer likely caused from the chemotherapy and full-body radiation that was needed to save my life. In the setting of metastatic cancer, concern over a secondary cancer is small, though this risk may become of greater concern if BRAF inhibitors are used in earlier stages of cancer (as adjuvant therapy) in the future. Prostate cancer patients treated with intensity-modulated radiation therapy (IMRT) do not have an increased risk of secondary cancers such as leukemia or myelodysplasia, compared to the standard 3D conformal radiotherapy. Hair loss. The damage from chemotherapy and radiation therapy can, however, affect the DNA of normal cells. The risk of secondary cancers from radiation therapy is improving as there is less "scatter" with newer techniques than in older techniques, meaning that less tissue is exposed. Each person experiences different side effects. Radiation of certain wavelengths, called ionizing radiation, has enough energy to damage DNA and cause cancer. While treatment has improved greatly, such as better localization of radiation so that fewer normal cells are damaged, a high rate of secondary cancers persists. In this discussion, we will not talk about metastatic cancer, but only a second primary cancer. These “secondary” cancers do not mean that the prostate cancer had spread; on the contrary, a new cancer has begun in a nearby organ (bladder, colon, rectum) because of exposure to radiation.

To compare the risk of secondary cancer from scattered and leakage doses following intensity-modulated radiotherapy (IMRT), volumetric arc therapy (VMAT) and tomotherapy (TOMO) in patients with lung cancer. Side effects depend on the type of cancer, its location, the radiation therapy dose, your general health, and other factors. These treatments often work by causing "oxidative damage" to the genetic material in cells. 10 Similarly, the relative risks of developing secondary cancer for patients surviving and years after EBRT for prostate cancer were estimated to be … Limiting processed foods and red meats can help ward off cancer risk.

This could cause it to become itchy, flaky, and dry later. Many people who get radiation therapy experience fatigue. The risk of secondary cancers after radiation therapy has become an important issue, mainly because advanced treatment techniques such as 3-D conformal radiation therapy (CRT) and intensity-modulated radiation therapy (IMRT) tend to increase the radiation dose to out-of-field organs. These changes depend on where you had radiation and the amount your doctor used. Cancer affects everyone differently.
