Stage 4 here and my doctors told me they estimate it had been there for roughly 2 years....BUT>>>>>> The best description I heard and simply the best reason to check it out was this...
He said that you can have a tumor the size of a pea and it be stage 4, spread to everything and have you on death's door.......or you can have a tumor the size of a basketball that is no harm at all and not even cancer.
As many have said, and this hold true for every post on this site, get checked out if you are having trouble. Since my diagnosis everyone in my family has been checked....brothers, parents, aunt, even my wife.
There are people that care about ya and we want the best for everyone, to make sure you take care of yourself.
