Hello! Thank you for the query. 1. Small GB polyp - this one should not be left alone as polyps can be misdiagnosed with gallbladder cancer. That is why every gallbladder with polyps should be surgical removed. 2. Mild fatty liver - this can be caused by alcohol abuse or by obesity and fatty foods intake. Fatty liver is reversible condition, however it leads to liver cirrhosis (which is not reversible) and can cause liver failure 3. Mildly enlarged prostate is not anything to worry about, however it should be observed and consulted with urologist to have tranrectal ultrasound with biopsy if necessary Your PSA level is fine and so is CEA, however CEA is not a good way to check if there is colon cancer or not. It elevates in about 50-80% of colon cancers mostly in late stages. Better way to check colon cancer risk is fecal occult blood and the best way is colonoscopy. Hope this will help. Regards.
