5 treatment settings, 4 with more than one named option. Each section lays out the options the standard of care names, what each is for, the trials behind them with their recorded results, the side effects and cautions on record, and questions to ask. Built from the cancer page's standard-of-care rows; nothing here is advice for your case.
Average-risk screening from age 45 (colonoscopy, faecal immunochemical test, stool DNA or blood test); earlier and more frequent colonoscopy for family history or a known syndrome; investigate rectal bleeding and iron deficiency promptly at any age.
Finding and removing polyps before they become cancer. Colonoscopy prevents cancer; stool and blood tests catch it early and get more people screened.
The first FDA-approved blood test for colorectal cancer screening (2024), now optionally reporting other cancers too.
A home stool test done every three years that looks for cancer DNA and hidden blood; a positive result means you need a colonoscopy.
No trial record is attached to this row yet. The trials tab lists what is recruiting and the landmark trials for this cancer.

Germline multigene testing for every patient; mismatch repair, RAS, BRAF and HER2 testing; fertility counselling before treatment.
A test of the DNA you were born with, to find inherited risk genes such as BRCA or Lynch syndrome.
Histopathology means looking at cancer cells under a microscope, and immunohistochemistry stains them for specific proteins. Together they are still the foundation of every diagnosis.

As for colorectal and rectal cancer by stage: surgery, adjuvant FOLFOX or CAPOX for stage III, total neoadjuvant therapy or organ preservation for rectal tumours; no escalation on the basis of age alone.
FOLFOX is the workhorse chemotherapy combination for bowel cancer, used after surgery to cure and in advanced disease as the backbone that targeted drugs are added to.
CAPOX pairs the oral fluoropyrimidine capecitabine with intravenous oxaliplatin as a pill-based alternative to FOLFOX. For low-risk stage III colon cancer three months after surgery works as well as six and halves nerve damage; it is also standard in gastric cancer, with hand-foot syndrome as its price.
Averages across everyone diagnosed, often years ago. A median is the middle of a group: half the people counted lived longer than the figure shown, and some lived far longer. Your stage, subtype, age, fitness and the treatment you receive matter more than the average, and the numbers are improving quickly.
No side-effect rates or interaction flags are recorded for these options yet. The side-effect lookup and interaction checker cover the products that have them.

Genotype-directed therapy as for all metastatic colorectal cancer: checkpoint blockade if mismatch-repair deficient, encorafenib-cetuximab for BRAF V600E, HER2 or KRAS G12C combinations, otherwise chemotherapy with bevacizumab or an anti-EGFR antibody by sidedness.
Pembrolizumab is a PD-1 blocking antibody approved in more than 40 settings, from melanoma and lung cancer to the first tumour-agnostic approval for mismatch-repair-deficient tumours in 2017, and before and after surgery in triple-negative breast cancer. A subcutaneous form arrived in 2025, and it is the backbone partner for ADCs and personalised neoantigen vaccines.
Encorafenib is a BRAF inhibitor that, with cetuximab and chemotherapy, became first-line standard for BRAF-mutant colorectal cancer in 2026.
A HER2-selective pill that works in the brain, for HER2-positive breast cancer with brain metastases.
Sotorasib (Lumakras) was the first drug to hit KRAS, approved in 2021 after four decades of failure.
Bevacizumab is a humanised antibody that soaks up VEGF-A, the signal tumours use to grow new blood vessels. Approved in 2004, it partners chemotherapy in colorectal, ovarian, cervical, lung, kidney and liver cancer and glioblastoma, and adds to trifluridine/tipiracil in late-line bowel cancer; hypertension, protein in the urine and bleeding are its characteristic side effects.
Cetuximab is a chimeric antibody that blocks the EGFR growth receptor. It is used with FOLFIRI or FOLFOX in RAS wild-type, left-sided bowel cancer, with encorafenib in BRAF V600E disease, with KRAS G12C inhibitors, and with radiation or chemotherapy in head and neck cancer; RAS-mutant tumours gain nothing and may be harmed, so RAS testing comes first.
