12 early warning signs that your body may be developing cancer cells

7. Changes in Bowel or Bladder Habits

Sudden constipation, diarrhea, blood in the stool, or changes in urination frequency can indicate colon, bladder, or prostate cancer.

8. Difficulty Swallowing

Difficulty swallowing, a feeling that something is stuck in the throat, or frequent choking can be related to esophageal or throat cancer.

9. Frequent Infections or Slow Healing

When your immune system is weakened by cancer cells, wounds take longer to heal, and infections are more common. Leukemia and blood cancers often present with this symptom.

10. Abnormal Bleeding or Discharge

Unexpected bleeding—such as coughing up blood, blood in the urine, or unusual vaginal bleeding—should never be ignored. This is a common early sign of cancers of the reproductive organs, bladder, or digestive tract.
