A cough lasting more than three weeks—especially if it produces blood—should never be ignored. Similarly, persistent hoarseness, loss of voice, or difficulty speaking can indicate lung, throat, or laryngeal can.cer. These symptoms often start subtly and are mistaken for infections like bronchitis, delaying diagnosis. If your cough or voice changes don’t improve, schedule a medical evaluation promptly.
6. Sores or Wounds That Do Not Heal
A sore, cut, or ulcer on the skin, mouth, or tongue that heals very slowly, enlarges, or bleeds easily may point to skin, oral, or cervical can.cer. Can.cer cells interfere with normal healing and reduce tissue regeneration. Any sore that does not heal within two to three weeks should be checked by a healthcare provider.
