- Masking: None
- Phase: None
- Number of Arms: None

Eligibility Criteria:
Inclusion Criteria:~* Age 50-80~* with a signed Informed Consent Form~* able to comply with the protocol requirements AND~* Confirmed primary diagnosis of colorectal cancer (stage I (1), II (2) and III (3)), or pre-- cancerous polyps, including tubulovillous or villous adenomas, with a biopsy available for study assays OR~* CRC-free and polyp-free colon using colonoscopy~Exclusion Criteria:~* Diagnosis of CRC relapse at the time of enrollment~* Inflammatory bowel disease~* Irritable bowel syndrome (IBS), confirmed at enrollment~* Pregnant, planning to become pregnant during the study timeline or nursing~* Cholecystectomy (gallbladder removal)~* Bariatric/gastric surgery~* Partial colectomy (colon removal)~* Partial bowel resection~* Pancreatic surgery~* Lynch syndrome~* Familial polyposis~* Patients from which the healthcare providers do not collect biopsy at colonoscopy AND undergo neoadjuvant therapy prior to surgery (the microbial composition of the biopsy at the time of surgery may be significantly affected by neoadjuvant therapy).~* Known autoimmune condition or impairment of immunological functions (e.g. HIV infection)~* Medications: Receipt of biologics, systemic immunosuppressive therapy, incl. cancer therapy, or antibiotics in the last 3 months before initial diagnosis~* Any vaccine taken within the last 30 days~* Current receipt of investigational agent

- Gender: ALL
- Minimum Age: 50 Years
- Maximum Age: 80 Years
- Healthy Volunteers: t

Study Arms:
- Cancer-free (Type: None): Have confirmed colorectal cancer-free and Polyp-free colon using colonoscopy
- Pre-cancerous (Type: None): Have benign or precancerous polyps, including tubulovillous or villous adenomas, using colonoscopy
- Colorectal cancer stage I (Type: None): Have confirmed TNM staging of colorectal cancer~The T refers to the size and extent of the main tumor. The main tumor is usually called the primary tumor.~The N refers to the number of nearby lymph nodes that have cancer. The M refers to whether the cancer has metastasized. This means that the cancer has spread from the primary tumor to other parts of the body.
- Colorectal cancer stage II (Type: None): Have confirmed TNM staging of colorectal cancer~The T refers to the size and extent of the main tumor. The main tumor is usually called the primary tumor.~The N refers to the number of nearby lymph nodes that have cancer. The M refers to whether the cancer has metastasized. This means that the cancer has spread from the primary tumor to other parts of the body.
- Colorectal cancer stage III (Type: None): Have confirmed TNM staging of colorectal cancer
