Save

A cough that lingers more than three weeks—especially if accompanied by hoarseness or blood—can be a warning sign of lung or throat cancer. From 2022 to 2025, ENT specialists noted an increase in referrals from patients ignoring a “harmless cold” that turned out to be early-stage cancer.

Low-dose CT scans are now covered under many cancer insurance packages and life insurance with early diagnosis clauses. If you smoke or have a family history, these tests are essential. Protect your health and finances by discussing respiratory symptoms with your doctor and updating your cancer-specific insurance plan.. If you have risk factors like smoking or family history, mention these during your consultation.
