Many of the colon cancers in younger people are related to mismatch repair mutations ie. Lynch syndrome. It may need inherited or it might be sporadic, but the progression to colon cancer is much faster in these patients than the traditional pathway. I'd be curious if OP knows the MMR status of their tumor

Most chemo regimens are quite standardized. Depending on the type of cancer, there may be additional more targeted therapeutics available, but some of this will depend on patient demographics. The chemo/oncology route is rough. My recommendation is to find an oncologist that your mom feels comfortable with and genuinely likes; they will be spending lots of time together and there needs to be mutual trust. While the regimen may be the same, I think the doctor-patient relationship is also crucial to healing.

Hey OP, do you know the MMR (mis-match repair) status of your tumor? Those with MMR mutations tend to present at a younger age but have better prognoses.
