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.

What Causes Colorectal Cancer?

Cancer occurs when a normal cell divides and multiples uncontrollably. Normally cells are regulated in their growth, maturity, division and death by the DNA present in their nucleus. With damage to the DNA the cells may become rogue and multiply uncontrollably to give rise to tumors.

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.

Colorectal cancer cases rise among younger adults in Germany

Colorectal cancer is generally considered a disease of older adults. However, a new analysis of German cancer registries shows that the number of new colorectal cancer cases among younger adults has risen slightly over the past two decades.

Accelerated biological aging may drive rising early-onset cancer risk

Cancer is often considered a disease of aging. Older adults are at higher risk because they have had more time to accumulate cellular damage that can trigger tumor formation.

Study identifies risk factors for early-onset colorectal cancer

A recent study found that factors such as a person's birthweight, sex, ethnicity, and father's age may affect the risk of being diagnosed with colorectal cancer at a young age.

GATA6 loss transforms colorectal cancer cells into metastatic states

Loss of GATA6-a transcription factor that controls which genes are turned on or off-can reprogram colorectal cancer cells into more primitive, adaptable states that can then spread to the liver and establish new tumors, according to Weill Cornell Medicine and Massachusetts Institute of Technology researchers.

Researchers advocate local data strategies for early cancer detection

Researchers are calling for the application of locally driven strategies, supported by stronger regional evidence, to improve early cancer detection and precise care.

Synthetic gut communities reveal how diet rewires the microbiome

Synthetic microbial communities give researchers controlled models for testing how diet reshapes gut microbial ecology, metabolism, and host-relevant responses. The review highlights how SynComs can strengthen causal inference, improve intervention testing, and support future precision nutrition, while noting major challenges in stability, standardization, and ecological realism.

Targeting immune cells could improve colorectal cancer treatments

Researchers at the Medical University of Vienna have described a mechanism in metastatic colorectal cancer that has received little attention to date: a key target of existing therapies, the so-called epidermal growth factor receptor (EGFR), is likely to affect more than just the cancer cells themselves.

Higher BMI raises risk for 19 cancers as global review expands the obesity-cancer link

A major systematic review and meta-analysis links higher BMI to increased risk of 19 cancer types, including leukemia, non-Hodgkin lymphoma, bladder cancer, and glioma, which were not previously recognized in major consensus reports. The study also reveals regional and sex-based variation in cancer risk, with genetic evidence generally supporting many observational links while highlighting the need for more diverse global cohorts.

Novel analysis identifies unique proliferation gene alterations in diverse cancer patients

New research to be presented today (Monday) at the annual conference of the European Society of Human Genetics shows that a cancer patient's genetic ancestry can have a significant effect both on how their disease progresses and their survival. In the largest study of its kind, researchers examined nearly 1,900 specific genetic changes in tumors in order to measure whether certain mutations were more common in patients with different historic geographic origins.
