Milton - I'm not Stage I, so I can't answer your main question -- which seems to be a question about recurrence for Stage I patients.
However, I do have a couple of comments to make, but these comments are not about cancer
recurrence but about long-term effects of cancer
treatments. As others have already said, the long-term or delayed effects of cancer treatments such as chemo or radiation can seriously affect a patient's quality of life (QOL) for the remainder of life. But since you won't be taking either chemo or radiation, this doesn't affect you.
However, you
did have two surgeries as part of your cancer treatment -- a Low Anterior Resection (LAR) and an ileostomy. Then later on you will have a third surgery -- an ileostomy reversal surgery. It turns out that these three surgical "treatments" can also have long-term adverse effects. In the case of LAR, the long-term effects relate to difficulties in bowel control (and perhaps also difficulties in bladder control or sexual function) due to whatever surgical maneuvers were done in the pelvic area during the operation. This collection of problems is called "the
LAR Syndrome" or
LARS for short. So, since you did have a Low Anterior Resection, you can expect that you will have a period of bowel re-training necessary after you have had your ileostomy reversal. You may need to work closely with your doctor(s) to work out a solution for overcoming whatever difficulties you may experience once you have had your reversal and once you are in the 5-year surveillance period.
Then there is another non-cancer problem to deal with, and that is the possibility of an
incisional hernia occurring either where your LAR incision was made or where your ileostomy incision was made (or possibly in both locations). This can happen if you lift very heavy weights or do something that produces a great deal of sudden pressure or tension in the abdominal area -- for example by coughing or sneezing very violently. If this happens and a hernia occurs, then there is no solution but to eventually have a hernia repair operation to try to fix the situation. As others have already mentioned on this forum, an incision like a LAR incision never heals completely. Even after months or years there is the possibility of a hernia occurring because there is one layer in the incision that does not, and cannot ever repair itself completely. This means that from now on your incision sites represent a weak point in your abdomen, so you must be careful about any abrupt abdominal movements or excessive pressures. This includes excessive pressure straining while on the toilet when dealing with constipation, etc.
I'm mentioning these things not to scare you but to alert you in advance to such facts, and to say that there are ways to prevent, avoid, or manage these kinds of things.
For example, to help with LARS you could try doing Kegel exercises, or pelvic floor exercises to strengthen your sphincter muscle response, which might, in turn, help reduce you bowel management difficulties. Then, for hernia prevention, you could invest in an abdominal binder (hernia belt) to use if and when you need to do heavy lifting (like lifting big suitcases) etc.
