14. Changes in Voice or Speech
Persistent hoarseness, slurred speech, or changes in vocal tone may signal cancers affecting the voice box (larynx), thyroid, or even the nervous system. This is particularly urgent if voice changes occur without any known cause like a cold.
15. Nagging Headaches or Neurological Symptoms
Frequent headaches, vision changes, seizures, or coordination loss may indicate brain tumors or neurological cancers. While many conditions can cause these symptoms, they should not be dismissed—especially when they appear suddenly or worsen over time.
When to See a Doctor
Early detection saves lives. If you experience any of these symptoms for more than two weeks—especially if they are unexplained, persistent, or worsening—seek immediate medical attention. Most symptoms listed can also be caused by non-cancerous conditions, but only a proper medical evaluation can determine the cause.
