Can the fluid injected into you during an MRI give a good idea as to whether or not a tumor is cancerous?

Question

I have a tumor in my lower spine. They just checked out the rest of the spine and head and didn't see anything else. But I was told by the tech. that what the tumor looks like with the fluid injected in my arm can help tell whether or not it is cancerous. Is this accurate?

An oncologist told me if cancer cells are present, the dye illuminates them.

Answer 2

No, a biopsy is needed to determine whether it is cancerous or not .
