Colonoscopy News and Research

RSS

Colonoscopy is examination of the inside of the colon using a colonoscope, inserted into the rectum. A colonoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue to be checked under a microscope for signs of disease.

Preventing colorectal cancer through lifestyle choices

The evidence is clear - screening for colorectal cancer may save one's life. Today, more and more people are choosing colorectal cancer screening. As a result, there is a steady decline in the number of older people getting and dying from colorectal cancer. Lower rates of smoking among Americans have also contributed to the decline in the past several years.

New gut-on-chip model could revolutionize immunotherapy for melanoma

A team of researchers from the European Institute of Oncology and the Politecnico di Milano, coordinated by Luigi Nezi, Team Leader of the Department of Experimental Oncology, European Institute of Oncology, and Marco Rasponi, Full Professor of the Department of Electronics, Informatics and Bioengineering, Politecnico di Milano, have developed a "gut-on-chip" (a miniature model of the human intestine on a chip-sized device) capable of reproducing the main features of intestinal inflammation and of predicting the response of melanoma patients to immunotherapy treatment.

Anti-TNF drugs proven to prevent perianal fistulas in Crohn's Disease

Early treatment of pediatric Crohn's disease with anti-tumor necrosis factor medications can substantially reduce the risk of perianal fistulas, a particularly debilitating complication of Crohn's disease.

He went in for a colonoscopy. The hospital charged $19,000 for two.

Tom Contos is an avid runner. When he started experiencing rectal bleeding in March, he thought exercise could be the cause and tried to ignore it. But he became increasingly worried when the bleeding continued for weeks.

Strategies to overcome social challenges in cancer prevention

Researchers at University of California San Diego and collaborating institutions have shed light on the ways that social risks, such as housing or food insecurity, pose barriers to routine cancer screenings.

DTI detects precancerous lesions in the pancreas

Precursor lesions of pancreatic cancer are very difficult to characterize with magnetic resonance imaging (MRI). But now, in a new study, researchers led by Noam Shemesh and Carlos Bilreiro – respectively head of the Preclinical MRI lab at Champalimaud Research and a doctor at the Champalimaud Clinical Centre's Radiology Department – have shown, for the first time, that a particular form of MRI, called Diffusion Tensor Imaging (DTI), is capable of robustly detecting pre-malignant lesions in the pancreas.

Accelerated aging linked to early-onset colorectal cancer, study shows

New research from Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine suggests that one's biological age, which can be higher than his or her chronological age – a concept called accelerated aging – may predict who's at risk for developing colon polyps, a known risk factor for colorectal cancer.

45 years of progress: Prevention and screening avert millions of cancer deaths

Research shows that cancer prevention and screening efforts prevented 5.94 million deaths across five major cancer types, highlighting their critical role.

Targeted intervention substantially boosts colorectal cancer screening rates

Colorectal cancer screening is an effective tool for catching the disease early when it's most treatable, yet it is underutilized in patient populations who receive primary care at federally qualified health centers (FQHC).

Research sheds light on how fecal transplants improve gut health

In a novel study that identified male chromosome genetic material in the intestines of female patients undergoing fecal transplants, researchers at Johns Hopkins Medicine say they have significantly expanded scientific understanding of how some of these transplants may succeed and work.

Weighing screening options for colorectal cancer in a changing landscape

Newly available blood tests to screen for colorectal cancer sound far more appealing than a standard colonoscopy. Instead of clearing your bowels and undergoing an invasive procedure, the tests require only a simple blood draw. But are the tests effective?

Earlier colorectal cancer screening can benefit younger adults

The updated national colorectal cancer screening guidelines that recommend screening begin at age 45 - rather than 50 - can benefit younger adults, a new Kaiser Permanente study found.

Innovative sensor material offers non-invasive cancer diagnosis

A research team led by Dr. Ho Sang Jung of the Advanced Bio and Healthcare Materials Research Division at the Korea Institute of Materials Science has developed an innovative sensor material that amplifies the optical signals of cancer metabolites in body fluids (saliva, mucus, urine, etc.) and analyzes them using artificial intelligence to diagnose cancer.
