Johns Hopkins study detects cancer in blood 3 years before diagnosis

While promising, this research raises serious concerns about premature implementation and potential harm. The study involved only 52 participants, making it far too small to draw definitive conclusions about effectiveness. Rolling out unproven screening tests to healthy populations could lead to unnecessary anxiety, overtreatment, and false positives without proven benefits.
