FINAL THOUGHTS:

If you ask your medical and/or surgical oncologist for some of the tests by type (germline/somatic) or brand name (Invitae, Guardant, Tempus, Caris, etc...) they might think you've done some homework and be a little more willing to order them. (Sad, but true experience based on self, relatives, friends)

If you ask the surgeon for more biopsy tissue than normal, many will hem and haw with some story about why it's not practical or beneficial, when a lot of times it's just extra work (paper and surgical) for them. This can take a couple weeks before surgery to get everything in place for this to happen, so plan on starting early.
