Yes, easily. My partner died of cancer at 30 despite exercising, avoiding alcohol, going for the screening, and generally trying her best.
Chances are it won't happen to you and your close ones. Perhaps try being grateful rather than dismissive?
[Edit: perhaps we have a misunderstanding as to the word "easily". I'm not saying it's likely, I'm saying it can and does happen without any warning signs and no amount of planning/preparation can save you.]
Nah, not even. I have a mutation called CDH1 that happens to be pathogenic and predisposes me to a greater than 40% chance of stomach cancer. It's a dominant gene which means it has a 50% chance I've passed it onto my daughter as well.
That cancer is what's known as a Hereditary Diffuse Gastric Cancer gene (HDGC). It just so happens that the E-cadherin control that suppresses those cancer cells is not processed properly. The diffuse part is what makes it particularly tricky. It's on the surface of the stomach epithelial cells and progresses from there. The only solution is a total gastrectomy (prophylactic if you do it early). No carcinogen necessary. It's found in populations all over the world and pathogenic lines don't even have to be related. The mutation can occur independently in the germline and is passed on. As long as you reproduce before it kills you nature really doesn't care.
Fun side fact. It also predisposes carriers to 70% chance of breast cancer. As a result many of those diagnosed are women who then find out they need to also have their stomachs removed.
Ouch, that’s a raw deal. Very very very sorry about you. If you don’t mind me asking, what are the consequences and mitigations necessary to live with a total stomach removal?
