What is the difference between radiation therapy and nuclear medicine?

What is the difference between radiation therapy and nuclear medicine?

Nuc Med injects dyes: In nuclear medicine, we inject radioactive "dyes" to image or treat patients. In radiation oncology, x-rays are generated outside the patient and irradiate tumors (usually) that are in the body. They treat different diseases. ...Read more

Nuclear Medicine (Definition)

The medical specialty of nuclear medicine involves the use of unsealed radioactive pharmaceuticals that can help image molecular flow throughout the body. The medical use of radiopharmaceuticals also includes the treatment of some cancers and bone pain. Nuclear medicine is separate from diagnostic radiology, which utilizes the use of external (sealed) radioactivity ...Read more

What are the differences between radiography, radiation therapy, and nuclear medicine?

What are the differences between radiography, radiation therapy, and nuclear medicine?

Different radiation: Radiography or x-ray involves low dose ionizing radiation with images of chest, skeleton, skull etc. Radiation therapy uses high dose ionizing to treat tumors with external or internal irradiation. Nuclear medicine involves low dose ionizing radiation in form of isotopes that are internally injected intravenously. Inhaled, injected subcutaneously, or ingested orally. ...Read more

Is nuclear medicine considered internal radiation therapy? For some reason, it seems like all the definitions of internal radi don't include nuclear.

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

What is the difference between radiography and radiation therapy for cancer?

What is the difference between radiography and radiation therapy for cancer?

Diagnose vs treat: Radiography means using x-ray beams to create an image that helps diagnose diseases including cancer. Chest x-rays and ct scans are common examples. Radiation therapy uses much higher powered radiation beams that are focused on cancer tumors. These radiation beams are designed to kill the cancer cells. ...Read more

Can you explain the main difference between treating cancer with radiation therapy and treating cancer with chemotherapy?

Radiation vs chemo: Radiation therapy is giving high-energy x-rays to tumors in a focal area of the body, causing dna damage in cancer cells. Chemotherapy is a medication commonly delivered intravenously or orally that then works throughout the body to kill cancer cells. ...Read more

Is mitomycin-n, an injectible medicine, a possible alternative to radiation therapy for cheek carcinoma?

No: Chemotherapy alone is not generally used for treating cancers of the head & neck. Surgery may be an alternative to radiation therapy for cheek cancers.

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?

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

Is there a point at which radiation therapy for cancer doesn't help enough to make the side effects worth it?

Is there a point at which radiation therapy for cancer doesn't help enough to make the side effects worth it?

Yes.: You don't always know if a treatment is going to work on a patient.

To the bed of. ..: Your condition is rising psa after definitive rx with radical prostate removal, which is relatively common in up to almost 1/3 after such surgery. The plan to radiate is termed as salvage radiation under assumption of local recurrence after updated imaging study shows no suspicion for metastasis. But no spread as reported in imaging studies doesn't mean absolutely no microscopic metastasis. ...Read more

Will someone explain radiation therapy?

Will someone explain radiation therapy?

Radiation therapy: Is the use of x-rays to treat cancer. Radiation works by damaging the dna of dividing cells. Since cancer is uncontrolled cell growth, radiation is more effective on cancer cells than normal cells. Radiation has been used for cancer treatment since the late 1800s. It's use depends on cancer location, type, and stage. Unlike chemotherapy, it is a local treatment that only effects the area treated. ...Read more

Please help me? What happens in radiation therapy?

Scrambled dna: A simplification: radiation sticks the stands of your dna together like stands of cold spaghetti. The dna still works, but when the cell trois to grow into two cells it can no longer pull the dna stands apart, so that each cell gets a copy. As a result, even though the cancer cells still function, they can no longer grow, and they eventually die. ...Read more
