But I remember at the time nearly having a heart attack over Stage
4 is when the cancer
in the colon
has spread outside the walls and goes to other organs. So, yes, she has Stage 4.
I can only guess why you ask, that perhaps you're thinking since it hasn't gone to the lungs or liver, it's not as serious. But once the cancer goes anywhere beyond the original site, it has to be considered a scary situation, to be sure.
