Re: Iodinated Contrast Agent & Cancer Reoccurence The iodinated contrast would not have stimulated the recurrence, but it does have a very difficult effect - for 2 to 10 months after, and even longer for some people, it makes the body less likely to uptake radioactive iodine, used for treating our thyroid cancer. Therefore, to use the gadolinium as contrast dye, it is bound to other molecules, which facilitate its travel through the bloodstream without causing harm (usually). This atomic state and electromagnetic charge is held by the atom until diluted in water and consumed. Check for active clinical trials using this agent. However, because the kidneys remove metformin, contrast medium can greatly increase the level of metformin in the blood because damaged kidneys are not as effective at removing metformin from the body. Gadolinium is a heavy metal and even a small amount is toxic to humans. You may be able to have the scan performed without contrast media or have an alternative imaging exam.
