Health anxiety. Advise what to do!

Hi What you’re describing fits very closely with health anxiety, not a physical illness. Your fear didn’t start randomly it was conditioned by repeated exposure to cancer-related losses (your friend’s grandfather, a YouTuber you admired). Your brain learned to associate cancer = sudden danger, and now it stays on constant alert, scanning your body for threat. The fear around touching your chest, repeated reassurance-seeking, and Googling symptoms are all anxiety-driven safety behaviors. Even though a doctor has already ruled out lumps, anxiety keeps asking, “What if they missed something?” this keeps the cycle alive. The solution is not more medical checks or Googling, because reassurance only gives short-term relief and strengthens the anxiety long-term. What actually helps is therapy focused on health anxiety especially CBT techniques like reducing body-checking, stopping symptom-searching, learning to tolerate uncertainty, and gradually retraining your brain to stop treating normal sensations as danger signals. With the right approach, this fear is very manageable and reversible. Take therapy. You can connect with me on nine two six six seven two six zero six five.
