Lung cancer is one of the leading causes of cancer-related deaths in the world. However, it's not necessarily lethal. If detected in the early stages, the symptoms may be contained, and its progression may be stemmed immediately. For diagnosis in the initial stages, you need to be aware of the warning signs. If any of the following symptoms are present, consult a doctor and get yourself checked for lung cancer.
When a cancerous growth is in one or both lungs, the breathing function of the body is naturally compromised. This often manifests as breathlessness, especially in the aftermath of mild physical exertion. If you find yourself panting hard after climbing a few stairs or incredibly breath-starved in cramped spaces like elevators, these are signs that your respiratory system is not functioning optimally.
