Gamma Knife Radiation Side Effects
Variable: Overall side effect profile is better than conventional radiation. Common side effects include- local pain, scalp swelling, headaches, discomfort from stablizing pin insertion. Other less common side effects include nausea, vomitting, skin rash, some hair loss, brain swelling or necrosis in the treated area. Seizure risk and hearing or visual changes are rare. ...Read moreSee 1 more doctor answer
This is light of extremely short wavelengths typically produced either among the stars / in cosmic rays or by radioactive element decay. Gamma rays form the background of normal radiation in which we all live; it is substantially greater than the exposure we get from imaging scans or should get from ...Read more
What are the effects of gamma knife radiation to the cavernous sinus cavity & pituitary gland due to an invasive atch secreting tumor?
Possible scarring: Pituitary adenomas are nearly always benign tumors, but can be quite locally destructive or infiltrative, making them difficult to remove from all of the nooks and crannies of the region. Radiation provides a way of controlling the growth. Cavernous sinus isn't usually affected, although rare thrombosis can be seen. ...Read moreSee 1 more doctor answer
Unlikely: Gamma knife is a targeted method for delivering radiation to a site routinely in the brain or spinal cord. Because of this targeting, there's less chance of collateral damage to bystander organs like those of your reproductive system. ...Read more
Not usually: With any type of radiation, the risk of side effects depends on the dose and body part being irradiated. Gamma knife is a technique that delivers a high dose to a small area of the body. If the testicles and pituitary gland are not exposed to a significant dose of radiation, fertility should not be effected. ...Read more
Should a healthy 35 y/o male with a 1.9cm acoustic neuroma be given radiation (Gamma Knife) as a long term treatment option?
Gamma knife: Is ONE option but please get a second opinion. Some docs may suggest monitoring it to see about growth or lack thereof. Please do what doctors say after you've seen several. Peace and good health. ...Read more
For a high grade glioma in an 82 yo, which treatment is better, gamma knife or stereotactic radiation therapy?
Stereotactic : Radiosurgery (srs), whether by gamma knife, cyberknife, or any other machine is not standard treatment for glioma. Glioma infiltrates into normal brain and so a generous "safety margin" of brain outside if the tumor or cavity must be treated. Conformal daily rt over many weeks safely treats the tumor infiltrating the brain. Srs cannot safely do that, but is sometimes used if standard rt fails. ...Read moreSee 2 more doctor answers
What should I expect for small cell lung cancer metastasized to the brain twice. I have been treated with gamma knife as well as whole brain radiation?
Watch out: The chance of further brain metastases is very high. You should have an MRI of the brain at least every other month, if not every month. Better to catch these tumors small when they can be treated with radiosurgery instead of more whole brain. Good luck, . ...Read moreSee 2 more doctor answers
What is the life expectancy of a 68 years old healthy person if nsc metastasized lung cancer has spread to brains and pelvic? Gamma knife and radiation already used, now chemotherapy.
Assuming you mean: Effects of radiotherapy when the mouth is being radiated? Dry mouth, then oropharyngeal mucositis, usually worse when chemotherapy is added. It is the reason i advocate a peg feeding tube before embarking on therapy. Swallowing functional impairment is the late effect. ...Read more
Quite varied dependi: The most common side effects are mild skin burn which may cause some redness after 2-3 weeks of starting radiation treatment. There are similar effects on the mucus memberanes which can become quite sore and sometimes form ulcers. There are also some long term effects on the internal organs which your radiation oncologist will inform you about, if you ask about them and share your concerns. ...Read more
Gi and Gu irritation: Gastrointestional(gi) irritation: rectal irritation more frequent bowel movement, diarrhea, hemorhoids may act up, blood in the stool. Genitourinary (gu): bladder irritation, irritation of urethra, more frequent urination, burning with urination, blood in urine. Fatigue is also a common side effect. ...Read moreSee 2 more doctor answers
Radioactive Dyes or: 'tracers' are special dyes usually given through an IV as part of a nuclear medicine study. Tracers contain a small amount of a radioactive isotope that decays naturally over time and is eliminated in the urine and stool. Most nuclear med procedures are painless except for mild discomfort associated with the iv. Allergic reactions to tracers are rare. Inform the tech if you could be pregnant. ...Read more
MRI doesn't: Use ionizing radiation (used with ct scans and plain x-rays studies). It uses magnetic fields to make images and these have not been shown to harm the human body. That said, patients with certain kinds of pacemakers and other implanted devices can't be imaged with MRI because of the potential to disrupt the device or otherwise harm the patient. ...Read more
Bowel & bladder :(: Fatigue(alleviated by rest), transient bowel and bladder irritation it is a common side effect. One may urinate or desiccate more frequently and may have some irritation related symptoms that are short-lived. They are typically managed well with medications. Uncommon and rare side effects are significant dysuria, obstruction of the urinary flow. There are medications that help with this. ...Read more
Radiation toxicities: The short term radiation effects depend on the location of treatment. Most common are diarrhea and skin erythema (pink sunburn type effect). Fatigue is also common. It depends on what organs are hit by the radiation therapy. Late effects are fibrosis (thickening of the tissue) and premature aging of the tissue. Permanent tanning of the skin can also occur. Ask your local radiation oncologist. ...Read more
I had 3 types of chemistry(ACT) and radiation 3 yrs. ago. Is it possible to still have side effects?
Side effects: Yes ,it is still possible to have side effects from your Chemo/ radiation treatments 3 year down the line------mostly from the radiation treatments-----it depends upon the dosage and the number of treatments ...Read more
Are there possible negative side effects from radiopharmaceuticals? I understand that radiopharmaceuticals is when radioactive substances are injected into the body, and i assume a low amount of radiation is ok, but when does the amount of radiation injec
In : In diagnostic nuclear medicine, our goal is to use the smallest amount of radioactive tracer that will give us the diagnosis. If you have ever been in a nuclear medicine department, you will be surprised at how long it takes to acquire an image. This is the trade off. Low tracer amounts yeild long imaging times. At some point, the patient can't hold still any longer. Your second question is when does radioactivity become harmful. Any sort of ionizing radiation can cause an increased risk of cancer. Sunlight, cosmic rays, and radiation coming from our environment will all cause a small increase of cancer rates. Because of this, we are always striving to keep our doses as low as reasonably achievable (alara). Please see :http://www.Ncsu.Edu/ehs/radiation/forms/alara.Pdf for more details. ...Read moreSee 1 more doctor answer
Too many: Side effects depend the area of the body which is being radiated- dry mouth & mouth sores (oral cancers), diarrhea (pelvic radiation), shortness of breath (lung radiation), hair loss (brain radiation), stomach ulcers and bleeding (stomach radiation). General side effects can include severe fatigue, low blood counts, skin rash and discoloration. ...Read moreSee 1 more doctor answer
