Major Warning Signs You Have Lung Cancer

Lung cancer, a formidable disease originating in the lungs, tragically remains the leading cause of cancer death in the United States. While smoking is a primary risk factor, a startling 15,000 non-smokers succumb to it annually, underscoring that no one is entirely immune. Early detection dramatically improves treatment outcomes. This article cuts through common misconceptions, spotlighting twelve crucial warning signs that often go overlooked or are dismissed as less serious ailments. Recognize these subtle yet significant indicators to empower yourself with timely action, regardless of your personal history. Your awareness could be your greatest defense.

1. Persistent Infections & Flu-Like Symptoms

Beyond just a "bad cold," recurring or persistent respiratory infections like bronchitis or pneumonia, especially those that linger or return quickly, warrant immediate attention. Unlike typical viral illnesses, lung cancer can weaken your respiratory system, making you unusually susceptible to infections that don't respond to standard treatments or recur with alarming frequency. If you're constantly feeling run down with prolonged coughs, fevers, or fatigue that mimic flu or cold symptoms but seem more intense or unusually long-lasting for no clear reason, it's a significant red flag that needs professional evaluation, even without overt breathing issues.
