I’ve read that there are some emerging theories of a bacterial component of colon cancer, which I find interesting [1][2][3]. A friend, also in his 30s, recently was diagnosed with colon cancer and it seems like doctors are really noticing an increase in colon cancer among a younger population. It just seems so young to be dealing with it. Regardless, I’m glad the author is recovering and found it early enough!
