Colorectal Cancer

Colorectal Cancer is cancer that develops in the colon (the longest part of the large intestine) and/or the rectum (the last several inches of the large intestine before the anus). In the United States, it is the fourth most common cancer in men and women. Caught early, it is often curable.

New biological feedback loop helps the immune system attack colorectal cancers

A subset of cancers, known as microsatellite instability (MSI) and deficient DNA mismatch repair (dMMR) cancers, are more visible to the immune system than others.

Six-gene signature predicts colorectal cancer recurrence after liver metastases

Researchers at The University of Texas MD Anderson Cancer Center identified a six-gene signature in microscopic colorectal cancer (CRC) liver metastases that may help predict recurrence after treatment.

Nine gut bacteria linked to future type 2 diabetes risk

Research identifies specific gut microbes associated with future type 2 diabetes risk, emphasizing the impact of dietary fiber on microbiome health.

Sexual and gender minority populations are less likely to receive cancer screening

A study reveals significant disparities in cancer screening rates among sexual and gender minorities, highlighting the need for equitable healthcare access.

Yogurt, prebiotics, and probiotics link to lower colorectal cancer odds in U.S. adults

A national NHANES analysis of 9,405 U.S. adults aged 50 and older found that any yogurt, prebiotic, or probiotic consumption was associated with about 50% lower odds of self-reported colorectal cancer. Because the study was cross-sectional, it cannot prove causation but supports further research into microbiota-targeted dietary strategies.

Microbiome science merges with oncology for better cancer treatments

Cancer remains notoriously difficult to treat, partly because tumors co‑opt their surrounding environment, including the resident microbiota, to evade immune surveillance and resist conventional therapies.

Persistent disparities found in preventive cancer care for sexual and gender minority populations

New research has uncovered persistent disparities in preventive cancer care across different sexual orientation and gender identity (SOGI) populations.

New study highlights noninvasive biomarkers for colorectal cancer detection

Emerging discoveries in liquid biomarker research promise to transform early detection, diagnosis, and treatment monitoring of colorectal cancer (CRC), according to a new study, offering less invasive alternatives to traditional methods that often require surgical interventions or tissue biopsies.

Allergies show a small but significant link to later cancer risk

A systematic review and meta-analysis of 28 cohort-based studies found a weak but statistically significant association between allergic diseases and later cancer incidence. The signal was strongest in the Western Pacific region and among people with asthma, but high heterogeneity and limited subgroup evidence mean the findings require caution.

Blood test may predict which colorectal cancer patients benefit from chemotherapy

A blood test may help identify which patients with colorectal cancer that has spread to the liver are most likely to benefit from chemotherapy after surgery, according to research presented today at the ESMO Gastrointestinal Cancers Congress 2026.

German study identifies therapeutic Achilles' heel for advanced colorectal cancer

A team led by researchers from the German Cancer Research Center (DKFZ) and the HI-STEM* Stem Cell Institute has discovered a promising new approach to treating advanced colorectal cancer.

New AI framework outperforms conventional biomarkers in predicting cancer survival

Digestive system cancers, including hepatobiliary and gastrointestinal malignancies, remain a major global oncological burden. Although immune checkpoint inhibitors have changed the treatment landscape for some patients, their overall efficacy remains limited, with only about 15% to 30% of patients achieving durable clinical benefit.

Could your birth characteristics influence colorectal cancer risk?

A California study links birth and parental factors to early-onset colorectal cancer risk, highlighting male sex and Hispanic ethnicity as key contributors.

Scientists find a universal gut microbiome pattern linked to colorectal cancer

Researchers analyzed 6,779 stool microbiome profiles and 906 tissue samples to identify a colorectal cancer microbial signature that remained consistent across age groups, populations, and sequencing methods. The signature aligned with tumor-resident microbes, showed weaker detection for adenomas, and was inversely associated with dietary fiber intake.
