Q re- Liver Polyp for Cancer Reg.?

There are strict guidelines and measurements that are made to evaluate if the polyp requires further attention or not, based on very accurate large-scale studies. If the doctors say you shouldn't be worried, there isn't a reason to be, there is a reason they spend over a decade learning what they do. If you are concerned then this is a subject to take up with your family doctor as he can explain this in more detail.
