More to it than just checking your poo, it often begins with mild stomach discomfort, which comes and go's, how many of us have stomach ache on and off but think it will go away eventually, back ache, is another symptom, not bad but niggly, tiredness, easy to brush off if you are a busy person. Its easy to dismiss all the symptoms as everyday niggles, the problem is that the screening is not totally reliable and blood tests can miss it, the only reliable diagnosis is a colostomy which is not the most pleasant experience.
Bowel cancer is a silent killer, most people put up with the mild ? symptoms until the cancer has spread to the liver and the lungs , even then you just feel a bit off colour.
There are a lot of effective treatments out there but they are brutal on the body, far worse than the original illness, chemo and associated treatments can hold it back, but at a price.
If you have the symptoms be insistent with your doctor, don't just settle for a blood test.
