I got a scar tissue in lung after radiation therapy for breast cancer. No one told me it could happen. What should I do?

Very rare, but...: ...Well-recognized complication of breast radiation therapy (of course, when you are that "one in a million", that doesn't help). Modern techniques are designed to maximize rx to the breast & minimize effects on the heart and lungs. Your radiation oncologist certainly should have discussed this with you pre-treatment--informed consent is a necessary part of any rx regimen. ...Read more

For what reason aren't patients shielded when they are receiving radiation therapy?

Shields are built in: Radiation therapy machines have the shields built in to them. These shape the radiation to fit the area of the body that needs to be treated and protects the rest.

Help please! is chemotherapy or radiation therapy more commonly used to treat childhood leukaemia?

Help please! is chemotherapy or radiation therapy more commonly used to treat childhood leukaemia?

More and more: We are moving away from cranial radiation in leukemia if we can. Leukemia cells use the central nervous system as a sanctuary site (ie., they hide there, and in the testes too). For patients with CNS disease at diagnosis, radiation is still a part of treatment. However, for CNS negative patients, we now use repeated intrathecal therapy for CNS prophylaxis. CNS relapse treatment involves radiation. ...Read more

Is there a reason I can't take antioxidants while i'm getting radiation therapy?

Is there a reason I can't take antioxidants while i'm getting radiation therapy?

Yes: Radiation takes advantage of free radicals formed in the field of radiation to cause dna damage targeted at cancer cells. Antioxidants are free radical scavengers, so they can potentially reduce the effectiveness of radiation treatments. It is best to avoid mega doses of antioxidants in the diet during and up to 6 weeks after radiation treatments. ...Read more

Why can't my father be around my children while he's having radiation therapy for his prostate?

Why can't my father be around my children while he's having radiation therapy for his prostate?

Seeds /y radioactive: Radioactive seed implant of prostate makes your father slightly radioactive for about 6 months when the amount of radioactivity has decreased significantly. Children have young organs prone to injury from radiation. Other forms of radiation like external beam radiation, imrt, igrt, cyberknife, high-dose-rate brachy therapy do not make your father radioactive. No risk to be around children. ...Read more

Yes: Nuclear Medicine includes tests such as PET and other scans that can assess tumors & evaluate the function of various organs. It also includes giving radioisotopes by mouth or vein for the treatment of certain cancers (most commonly thyroid, lymphoma and bone mets) and hyperthyroidism. This is different than brachytherapy done by Radiation Oncologists in which radioactive seeds are put in a tumor ...Read more

Can radiation therapy increase cell growth?

No and Yes: Radiation therapy slows or stops cell growth. The goal is of course to kill cancer cells and they don't grow and die. However if you look up the four r's of radiation biology. The last one is repoplulation in which during fractionated radiation cells increase growth to repopulate. Luckily we see this more often in the good cells but unfortunately in some cases resistant cancer cells. ...Read more
