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.
A new study by Johns Hopkins researchers found that older men have more extensive prostate disease even if their PSA levels are the same as younger men. The study suggests that age should be an additional guide in deciding whether to do further testing for non-palpable prostate cancer.
Women in their 40s benefit more from annual mammography screening due to detectable cancers being larger and more aggressive. Mammograms for younger women are less effective compared to breast palpation, which also faces similar limitations in denser pre-menopausal breasts.
Research reveals that positive feedback from law enforcement can distort eyewitness memories, making them more confident and accurate. The study suggests that this distortion can lead to innocent convictions, highlighting the need for supervised lineups and confidence assessments.
