Not yet but...: First, MRI's have no radiation & don't increase cancer risk. CT scans expose you to 150-1100 times the amount of radiation of a regular X-ray but even with 3 in a year the odds you will get cancer from that exposure is extremely small. probably no more than 1-2%, and it would take many years for it to develop.

Extremely unlikely: So unlikely that the likelihood approaches zero. You have more radiation exposure on a cross country flight, or hiking at altitude. That said, WHY did you have all those scans? If you have had unintentional weight loss, night sweats, or other unexplained pain, the scans may be looking for cancer. But the risk of cancer due to the scans is nearly zero. Why did you have them?

I had one worm-shaped blood clot in my urine 2 weeks ago. My urologist wants to perform a cystoscopy and abdom/pelvic CT to rule out cancer. However, Ive had numerous CTs over the years incl. one just 8 months ago. Can MRI and/or US be substituted?
