Congratulations with your good results and I wish you fast recovery.
In Belgium every +50 individual receives a sample tube automatically in his postbox for a preventive research of intestinal cancer. It is free of charge. I also have sent my sample and been contacted by a doctor after 2 weeks. There was some inflammation found and a colonoscopie was needed to search the reason behind it.
It is indeed an embarassing test by thoughts. But in practice you don't even feel it or know that it has happened under sedation. Finally they have found and removed a polyp. Further they have found a piece of bamboe stick stuck in my intestine wall which has caused the inflammation. Polyp was tested and no cancer risico found. Advice they gave was being more carefull at BBQ times🤣.
Luckily I had no issues. But even being contacted for a colonoscopie, going through it and waiting for the results is scary enough.
