How safe is an ultrasound scan as regards cancer promoting effects?

Question

Scans and xrays, said a recent study, promote cancer. But some say ultrasound scans are not that harmful. I would like to know how far this is true so that we can make practical decisions related to this.

Answer 1

Ultrasounds use sound waves, not radiation. Cancer isn't caused by soundwaves, so it's fine.

Answer 2

The only known effect of ultrasound on the human body is concerning the internal temperature. Some studies suggested that a long ultrasound exam can locally raise the temperature between 0.5-1.0 degree. This effect could be especially real with the use of Doppler technique when studying the vascular structures.

But then the next question is : what is the effect of raising the temperature. There is no fact to proove that a 0.5-1.0 degree raise can cause cancer. So we can conclude that ultrasound is harmless. We are usually only aware of using Doppler on a first trimester obstetrical ultrasound; to avoid raising the local temperature on the 5 mm fetus.

Answer 3

Thyroid maximum cancers in a 26 twelve months previous isn't very complication-unfastened. Over an 8 month era of persist with-up, this would desire to have progressed if it have been a malignancy. From the information superhighway internet site listed decrease than, "ninety 9% of thyroid nodules at the instant are not maximum cancers." Small residual non-gentle lymph nodes interior the a million cm variety are frequently chanced on interior the top cervical chain in the back of an ear or interior the supraclavicular area. CT scans frequently won't %. up small residual nodes interior the a million cm variety in those factors. (I would desire to wager on the dimensions because you probably did no longer let us know how super the lymph nodes are. in the event that they have been 2 cm or greater, your medical doctors could in all probability be ordering a biopsy.) if your thyroid examine - particularly the TSH - are all conventional, the tiredness should not be on the subject remember of hypothyroidism. there are various issues that would reason well-known fatigue different than hypothyroidism. A thyroid malignancy this small does not be sufficiently huge to reason well-known fatigue. that's what makes inner drugs so complicated - attempting to style by way of each and all of the attainable issues and locate the only that explains your difficulty - - and with a bit of luck facilitates a favorable healing intervention. the main would be persist with-up and an mind-blowing form of careful questioning on your surgeon's section. each and every so often the suitable attempt is the "attempt of time."
