https://phys.org/ en-us Latest news from The JAMA Network Journals After a stable 15-year trend, local-stage colorectal cancer (CRC) incidence increased steeply in adults aged 45 to 49 from 2019–2022, including a 50% relative increase between 2021 and 2022. This trend contrasts with consistent increases of distant-stage diagnoses in this age group and likely reflects the diagnosis of prevalent asymptomatic cancer through first-time screening due to recommendations for adults to begin screening at age 45 instead of age 50. https://medicalxpress.com/news/2025-08-lowering-bowel-cancer-screening-age.html Health Mon, 04 Aug 2025 14:50:03 EDT news673537802 Dads with poor mental health may be impacting the development of their kids, with Australian research linking mental distress in fathers to poorer social-emotional, cognitive, language, and physical development in their kids. The review, which pooled together the results from 84 studies across 48 groups of people, found that these impacts were generally stronger for mental distress after birth than before birth, suggesting that a father's mental state may exert a more direct influence on the developing child after birth. https://medicalxpress.com/news/2025-06-dad-mental-health-linked-kid.html Psychology & Psychiatry
