Researchers delving into the timing of subsequent colonoscopies found that for some people, the risks are no different if they wait 15 years instead of 10. The invasive and expensive nature of colonoscopies makes determining how to maximize their usefulness—particularly when it comes to follow-up screenings—a prominent topic of research. It’s undisputed that the surgical-based test can save lives, but the timing remains a moving target. Three years ago, the U.S. Preventive Services Task Force lowered the recommended age for the first colorectal cancer screening by five years—from 50 years of age to 45. Now, the gap between the first and second tests is being scrutinized. Long-term data used in a JAMA Oncology study published May 2, 2024 suggests it may be time to move the follow-up screening back five years in certain circumstances. Specifically, the study indicates that anyone who doesn’t have a family history of colorectal cancer and whose first colonoscopy was free of polyps—abnorm...

Introduction: Why Oxygen Matters in Cancer A  thorough understanding of the problem is half of the solution —and in cancer, one of the most overlooked problems is  tumor hypoxia  (low oxygen levels inside tumors). Hypoxia isn’t just a byproduct of tumor growth. It actively drives: Treatment resistance Metastasis Immune suppression Aggressive tumor behavior At the center of this process is Hypoxia-inducible factor 1-alpha (HIF-1α), a master regulator that helps cancer cells adapt and survive under low-oxygen conditions. This is where  hyperbaric oxygen therapy (HBOT)  comes in. Credit (1) What Is HBOT and How Does It Work? Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen at elevated pressure, dramatically increasing oxygen delivery to tissues. Key anticancer mechanisms: Reverses tumor hypoxia Increases reactive oxygen species (ROS) → cancer cell stress Enhances radiotherapy effectiveness Improves drug penetration Reduces hypoxia-driven resistance...
