The AGA Institute concludes that CT colonography is a viable colorectal cancer screening option, detecting 90% of large polyps. However, small polyps are less detectable, and radiation risks are still uncertain. Colonoscopy remains the definitive test for early detection and prevention.
A new study found that people with an initial negative colonoscopy have a very low risk of developing colorectal cancer within five years. Based on this study, rescreening may not be necessary sooner than five years after the initial screening. The study's findings confirm what many gastroenterologists already believed.
Researchers at UC Davis have developed an interactive multimedia computer program to provide personalized education on colorectal cancer screening. The program aims to increase screening rates among Hispanic patients, who are less likely to receive screenings compared to non-Hispanic whites.
Regular breast cancer screening programs in developed countries show promise for reducing mortality in India. A new study estimates that annual or biennial clinical breast exams can lower mortality rates by 8.2% and gain life years at a cost-effectiveness of $1,135 per life-year gained.
A new analysis reveals that fewer than half of older patients with colorectal cancer receive the recommended screening schedule to detect any recurrence. The study found that some patients may not meet guideline standards due to other procedures, while others receive testing that goes beyond guidelines.
A study published by researchers at Duke University Medical Center found that only one-fifth of men under age 50 reported undergoing a PSA test in the previous year. Black men and men with a family history are disproportionately affected, highlighting the need for increased awareness and screening efforts.
A study found that one in five men in their 40s have undergone a PSA test within the previous year. Young black men are more likely than young white men to have been screened. The study also revealed that younger Hispanic men and those with higher household income and education level were more likely to undergo testing.

A new study reveals that mammography rates have declined significantly in the US between 2000 and 2005, with a notable decrease among women aged 50-64 and higher socioeconomic levels. The decline in screening rates coincides with a reduction in reported breast cancer incidence, raising concerns about potential impact on mortality rates.
A lung cancer screening regimen has been found to identify patients with early-stage cancer, allowing for curative treatment. The study suggests that annual repeat screenings can detect lung cancer at its earliest stage, resulting in a high proportion of patients having no evidence of metastases.
