Doctors Highlight Persistent Cough and Other Early Signs of Lung Cancer

In India, persistent cough is often linked to tuberculosis (TB), but medical experts warn it can also signal early lung cancer. Doctors emphasize that a cough lasting more than three to five weeks, especially if worsening, accompanied by symptoms like coughing blood, breathlessness, wheezing, or fatigue, requires prompt medical evaluation. Early detection of lung cancer, which may initially present with mild symptoms, can improve treatment outcomes, particularly for smokers and high-risk individuals.
