5. Unexplained Fatigue: More Than Just Tiredness
Everyone gets tired, but a deep, unexplainable fatigue that doesn’t improve with rest can be a sign of lung cancer. It’s not the run-of-the-mill tiredness that comes from a long day or lack of sleep. It’s a profound, persistent fatigue that seems to have no origin and doesn’t go away with sleep.
This fatigue isn’t just confined to the body; it seeps into your mental state, too. You might find it hard to concentrate, make decisions, or even carry out simple tasks. The fatigue can be so debilitating that it affects your ability to lead a normal life, yet it’s a symptom often overlooked because, well, life is exhausting sometimes.
Interestingly, the fatigue might come and go in waves, almost like phases of the moon. There could be periods where you feel relatively normal, interspersed with stretches of intense fatigue. It’s this inconsistent pattern that often makes people underestimate the severity of the symptom. (5)
