What I described as "par for the course" is about what they are going to start with, +- maybe LDH, and unrelated stuff like thyroid and cholesterol tests.
You may get them to get the CA19-9, expand CHEM12 or 14 to a "Super Chemistry
" (packages vary) with the "extra" GGT, LDH, BILI (rubin), hsCRP, ESR and ferritin, maybe fasting insulin. Quantitative d-dimer, any family history of clots or embolisms you might be able claim to dr. If he won't give you 25 hydroxy vitamin D for a colorectal cancer dx, (s)he's behind other doctors here. Remember this is for a baseline or a benchmark and for initially spotting anomalies, you won't use this many panels everytime.
US doctors WILL look askance about all the extra markers (CA19-9, AFP, CA125, CA72-4), it's outside their training and your insurance's guidelines. Also d-dimer may flip ordinary doctors out, so self order only may be best. Some countries' labs will do 6-12 cancer markers, "cancer screen", all together at one time, cheaply, but I haven't seen it for the US yet. Be prepared to advocate and argue for them, then have to order them yourself online.
Because of the inflammation markers, and consistency, it is best if you can get everything together at once, especially if you are able to get the same lab for the next year or two.[I just realized you're in Canada, I believe they are stickier about "standard", you'll need even better narrative skills, but let us know]
