A study found that CT colonography can detect cancer lesions and polyps with nearly the same sensitivity as colonoscopy, avoiding fatal perforations but potentially leading to more cancer-related deaths. The method's higher cost is offset by its non-invasive nature and appeal to patients.
The blood test aims to identify individuals with improper control of the growth-promoting gene insulin-like growth factor 2 (IGF-2), which is associated with a higher risk of colon cancer. If successful, the test could help monitor those who need invasive colonoscopy or suggest dietary changes to reduce their risk.
Researchers found that combining interferon with irinotecan boosts IRF5 protein levels in colon cancer cells, leading to increased cell death. The combination therapy may limit side effects and make it harder for cancer cells to build resistance.
Researchers have identified a gene marker called vimentin that detects colon cancer with 46% accuracy using DNA stool tests. The marker has potential to be used in combination with other DNA markers to detect 100% of colon cancers.
Research has found a positive association between body mass index, fat-free mass, and waist circumference with an increased risk of myeloid leukemia. Additionally, modifications of the vimentin gene can be detected in fecal DNA of people with colon cancer, potentially serving as a biomarker for the disease.
A study found that 43% of women prefer female endoscopists, with 87% willing to wait for a female doctor and 14% willing to pay more. This preference may hinder colon cancer screening among women, emphasizing the need for targeted prevention programs.
A study found that 45 out of 500 virtual colonoscopy patients had clinically important extracolonic findings, including kidney cancers and abdominal aortic aneurysms. The study suggests that virtual colonoscopy may be more effective at detecting diseases outside the colon than in the colon.
A recent study found that virtual colonoscopy can detect extracolonic abnormalities in 63% of patients, with clinically important findings detected in 9%. The procedure is potentially cost-effective and can be used to screen for other conditions as well.

The researchers emphasize the need for targeted interventions to increase screening rates in poor and uninsured communities.
A large study of 39,876 healthy women found no effect of vitamin E on total cancer or cardiovascular disease. However, vitamin E supplementation was associated with a reduced risk of cardiovascular deaths among all women and a decrease in heart attacks and cardiovascular deaths among women aged 65 years and older.
A recent study published in The Lancet Oncology has found that keyhole surgery is a safe and effective option for treating colon cancer. Patients who underwent keyhole surgery had less blood loss, shorter hospital stays, and faster recovery times compared to those who received open surgery.
Increased expression of claudin-1 has been found in human primary colon carcinomas and metastases. Claudin-1's mislocalization is associated with higher levels of expression and increased metastatic behavior in colon cancer cells.
