6. Persistent Cough or Hoarseness
A cough lasting more than three weeks, especially with blood, could point to lung or throat cancer. Hoarseness that doesn’t improve may also be a warning sign.
7. Changes in Bowel or Bladder Habits
Sudden constipation, diarrhea, blood in the stool, or changes in urination frequency may signal colon, bladder, or prostate cancer.
8. Difficulty Swallowing
Trouble swallowing food, feeling like something is stuck in your throat, or frequent choking could be related to cancers of the esophagus or throat.
9. Frequent Infections or Slow Healing
If your immune system is compromised by cancer cells, wounds take longer to heal and infections occur more often. Leukemia and blood-related cancers often show this symptom.
10. Abnormal Bleeding or Discharge
Unexpected bleeding—such as coughing up blood, blood in urine, or unusual vaginal bleeding—should never be ignored. This is a common early sign of cancers in reproductive organs, bladder, or digestive tract.
