All radiation: It is dose related and dependent on whether it is ionizing (alpha or beta rays), or non-ionizing (gamma and x-rays). Very slight increases in cancer occur in people with many x-rays.
Dr. Timothy Davis
Radiology 25 years experience
Not likely: Radiation exposure varies widely with the test. We try to minimize, but risk is small. Ct is the most concerning modality. There is tiny risk with each scan. Because cancer is so common, tiny risk increase is difficult to measure. Your lifetime chance of cancer overall is already very high without imaging, and about 1 in 1000 of the cancers you could get might be caused by ct scans.
Dr. Joseph Accurso
Radiology 29 years experience
Yes but very lo risk: All ionizing radiation can induce genetic damage which could lead to cancer. However, this is related to the type of radiation, frequency and intensity. There is no good data at the low levels used. Ct has the highest radiation dose. However it is an extremely useful tool and the radiation risk should not prevent its use when clinically indicated. Medical necessity should drive imaging use.

Repeat the test: Sometimes it takes up to a weeks for the urine test to turn +. If you feel pregnant and continue to have a negative urine test i suggest that you have the more definitive blood test.

Water retention: It could be other things, but probably some lingering hormonal changes like water retention. If you think pregnancy is possible, then do a test.

I have puss on tonceles and large bumps on back of tongue and throat but don't hurt. Do u know what could be wrong?

Probably normal: If you do not have pain and no fever then this may be normal. All of our tongues have bumps on the back of them and just maybe you never noticed them. The tonsils can collect debris and dead cells that slough off and these can collect as small white plugs in the tonsil itself. If there is no pain it is unlikely that you have an infection.
