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.
Most of the tests that doctors use to diagnose cancer -- such as mammography, colonoscopy, and CT scans -- are based on imaging. More recently, researchers have also developed molecular diagnostics that can detect specific cancer-associated molecules that circulate in bodily fluids like blood or urine.
Writing in the July 12, 2021 online issue of Nature Communications, researchers at University of California San Diego School of Medicine describe a new approach that uses machine learning to hunt for disease targets and then predicts whether a drug is likely to receive FDA approval.
The numbers of cancer screening tests rebounded sharply in the last quarter of 2020, following a dramatic decline in the first months of the COVID-19 pandemic, at one large hospital system in the Northeastern United States. These findings were released in a study published in Cancer Cell.
A colonoscopy might cost you or your insurer a few hundred dollars — or several thousand, depending on which hospital or insurer you use.
Black people have a higher risk of colorectal cancer than white people, but this risk is likely not due to genetics.
New technology that will marry probes that can detect cancer tumors through the skin with high-precision robotic surgery is to be developed for use in hospital settings for the first time in a project led by the University of Warwick.
Colorectal cancer rates among young adults are steadily increasing over the years. The United States Task Force has long recommended that people aged 50 to 75 get screened. Now, the U.S. Preventive Services Task Force updated its 2016 recommendation of colorectal screening for people aged 50, down to 45 years old. The five-year earlier screening can save many lives by allowing earlier diagnosis and treatment of the condition.
A landmark work that details the strengths and weaknesses of the U.S. health insurance system, including how it lags behind those of other wealthy countries in measures that include mortality from both preventable and treatable causes, has been published.
Cancer of the colon and rectum is one of the deadliest forms of cancer, and has in recent years affected growing numbers of young people.
Patients with one or more health conditions are more likely to be screened for colorectal cancer than those without comorbidities, according to new research in the Journal of Osteopathic Medicine.
A UCLA-led study shows that physicians frequently order preventive medical services for adult Medicare beneficiaries that are considered unnecessary and of "low value" by the U.S. Preventive Services Task Force -; at a cost of $478 million per year.
A new Mayo Clinic study bolsters evidence that colorectal cancer is often imprinted in family genes and passed on from one generation to the next.
Experts have uncovered a new molecular reason why faecal transplants are highly effective in treating infections such as C. difficile (a nasty bacteria that can infect the bowel), which could lead to more targeted treatments for this and other similar diseases.
Today, the U.S. Food and Drug Administration authorized marketing of the GI Genius, the first device that uses artificial intelligence (AI) based on machine learning to assist clinicians in detecting lesions (such as polyps or suspected tumors) in the colon in real time during a colonoscopy.
Statistical modeling developed by Oregon State University researchers has confirmed that changes to melanoma patients' gut microbiome led them to respond to a type of treatment capable of providing long-term benefit.
Colorectal cancer screening rates jumped by more than 1,000 percent when researchers sent take-at-home tests to patients overdue for testing at a community health center that predominantly serves people of color.
Researchers at UPMC Hillman Cancer Center and the National Cancer Institute demonstrate that changing the gut microbiome can transform patients with advanced melanoma who never responded to immunotherapy-;which has a failure rate of 40% for this type of cancer-;into patients who do.
Colorectal cancer is the second most common cause of cancer-related mortality among men and women in the United States, according to the American Cancer Society. At-home tests, which measure blood in stool as a potential marker for colon cancer, are often used for colorectal cancer screening.
A new Veterans Affairs study finds that delays in undergoing colonoscopy following an abnormal stool test increase the risk of a colorectal cancer diagnosis and cancer-related death.
New research has demonstrated that a simple, cheap test can help identify who is at risk of developing colorectal cancer, aiding early diagnosis and potentially saving lives.
