Lung Cancer Awareness
With rising pollution levels and unhealthy lifestyle habits, the risk of lung cancer is increasing rapidly. Recognizing early signs of lung-related problems and lung cancer is essential for timely diagnosis and treatment.
Lung cancer occurs when abnormal cells begin to grow uncontrollably in the lung tissues. If not detected early, these cells can spread to other parts of the body. Here are the early symptoms that may help you identify lung cancer at its initial stage.
A long-lasting cough is one of the most common early symptoms. In some cases, it may come with mucus or phlegm.
While coughing up mucus is common, the presence of blood is not normal. It can be an indication of a serious lung condition, including lung cancer.
Lung-related problems often affect the respiratory system, making breathing difficult.
Pain in the chest while breathing, laughing, or coughing is another warning sign.
Lung cancer can cause hoarseness or changes in the voice.
Unexplained tiredness and sudden weight loss can also be associated with lung cancer.
Several risk factors can increase the chances of developing lung cancer:
Smoking is the biggest cause of lung cancer.
Passive smoking (being around a smoker) can also increase risk.
Air pollution is another major contributor.
Radiation exposure, especially during treatments for previous cancers, may also elevate risks.
Diagnosis usually includes:
Physical examination
Blood tests
Chest X-ray
CT scan
Biopsy (in some cases)
