If colon cancer was causing pain RUQ wouldn't it be big enough to show on CT of abdomen and pelvis? 31 yo- fecal occult blood negative

In brief: Not likely colon Ca

Classic colon cancer causes pain via colon obstruction, so in that case, CT would see it.
But this would not be expected in a 31 yo w/ occult neg stool. RUQ pain can be any number of causes in young adult. Need to know more history and clinical exam by a Dr. to advise work up. Best screen for colon Ca is colonoscopy, but unless strong family history, may start around 50 yrs old.
