I want to confirm a few technical details about my diagnosis and treatment and clarify whether any complementary approaches raise concerns.

1. Tumor Classification (Confirmation)
Can you confirm that my tumor classification is correct?
-- MMR status: MSS / pMMR
-- Meaning: Microsatellite stable; mismatch repair proficient

2. Immunogenetics
What is my HLA (human leukocyte antigen) type?
-- Has this already been tested?
-- If not, is there value in testing it now?

3. Compatibility With Eastern / Chinese Medicine Herbs
Are there any concerns, interactions, or contraindications with using the following herbs alongside my current treatment?
-- Mai Men Dong (Ophiopogon root)
-- Bai Shao (White Peony root)
-- Chen Pi (Aged Tangerine Peel)
