Pet Ct Thyroid Cancer Restaging
What can be done to reduce cancer risk after CT scan (chest). I m worried about thyroid cancer as it is related to chest CT scan.
Don't worry: Hello - the radiation exposure from one ct scan is low. You do not need to worry about thyroid cancer because of a ct. We are exposed to radiation throughout our normal daily routines and when we fly. If you'd like you can limit other exposures. Request pat-downs at security at airports instead of the scanner for example. I don't think you need to do anything, however. ...Read more
Computed tomography is also known as CT scan. Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Can chest CT scan puts me at the higher risk of thyroid cancer? Chest CT was done with contrast. Can contrast used in chest CT damage thyroid?
Yes, no: There is some evidence that chest ct could put one at higher risk for thyroid cancer - but almost all of these suggest that it is dose dependent and that it would take repeated scans/exposure to elevate the risk. You can request protective covering for thyroid if need additional scans. The contrast used will not cause thyroid damage or disease. ...Read more

Dx breast cancer at 39, thyroid cancer at 40. Is a PET scan needed to rule out mets and am I at a risk for other cancers?
Possibly: Hereditary predisposition to certain cancers usually occur at earlier ages. At age of less than 50 yrs you would qualify for genetic testing for BRCA 1 & 2 mutations. A PET scan depending on the clinical situation can detect spread of disease (not as good in the brain) to other organs but in someone with BRCA gene mutation, the development of other kinds of cancer may not occur at the same time. ...Read moreSee 2 more doctor answers
I'll need radioactive iodine therapy in 2 weeks for my thyroid cancer.How can I get rid faster of the iodine in my body from a CT scan i had yesterday?
Not likely to work: If you received IV contrast with the ct scan, you will not be able to receive radioactive iodine in 2 weeks. It can take months for the iodine from the contrast to be excreted. You may be able to increase the rate slightly by taking a diuretic, but the best thing will be to wait at least 2 months. ...Read more

Thyroid cancer arises in the thyroid gland. It usually presents as a painless thyroid nodule. Most are papillary-follicular type and have a very good prognosis. Less common are medullary cancers, with an intermediate prognosis. Anaplastic cancers of the thyroid have a poor prognosis and are uncommon. Treatment of thyroid cancers involves removal ...Read more
