A recent study published in the American Journal of Roentgenology found that virtual colonoscopy is equally effective for detecting both flat and non-flat types of lesions. The study detected 80% of flat lesions and 81% of non-flat lesions, with no diminutive flat lesions showing histological advanced lesions.
Researchers found that calcium supplementation slightly decreases the risk of all types of colorectal polyps, with a greater effect on advanced lesions. A diet high in fiber and low in fat also shows promise in increasing the preventive effect of calcium.
Researchers studied 40 patients with 42 adrenal masses and found that MRI was more sensitive than CT in characterizing lipid-rich adenomas. The study's findings suggest that MRI may be the preferred imaging modality for detecting adrenal adenomas, particularly in cases where symptoms are present or a history of cancer is known.
A new study found that beta-carotene supplementation increased colorectal adenoma recurrence risk among smokers and heavy drinkers. Randomized trials showed a significant decrease in adenoma recurrence risk without smoking or drinking, but paradoxical results when exposed to these lifestyle factors.
A new randomized study found that beta-carotene supplementation increased cancer risk in smokers and drinkers, while decreasing risk in non-smokers and non-drinkers. The study's findings highlight the complexity of designing safe and effective chemopreventive strategies for any cancer.
A new study uses computational tools to track human cancer development, suggesting that adenoma and carcinoma lines can arise from a common precursor but develop in parallel. This challenges the conventional model of cancer progression, which assumes a linear process from normal cell to polyp to cancer.
Researchers found that relatives of individuals with colon polyps have a slightly less than doubling of risk compared to the general population, rising to about 10-12% over a lifetime. The study suggests that these individuals should receive colonoscopy instead of sigmoidoscopy for screening.
