6. Persistent Cough or Hoarseness
A cough lasting more than three weeks or hoarseness that doesn’t go away can be an early sign of lung cancer or throat cancer.
7. Changes in Bowel or Bladder Habits
Constipation, diarrhea, or changes in stool color or shape can be signs of colorectal cancer. Frequent urination or pain while urinating can signal prostate or bladder cancer.
8. Swelling or Lumps
A lump under the skin, especially in the breast, testicles, or lymph nodes, should never be ignored. Early detection of lumps can make treatment far more effective.
9. Difficulty Swallowing
Trouble swallowing or the feeling of food getting stuck can indicate esophageal, throat, or stomach cancer.
10. Indigestion or Persistent Heartburn
If indigestion or heartburn continues for weeks despite treatment, it could be a sign of stomach, throat, or pancreatic cancer.
11. Night Sweats or Fever
Frequent fevers or drenching night sweats without infection could point to lymphoma, leukemia, or other cancers.
12. Slow-Healing Sores
Mouth sores that don’t heal could indicate oral cancer. Ulcers or wounds on the skin that won’t heal might be skin cancer.
✅ When to See a Doctor
If you experience any of these symptoms for more than two weeks, schedule a medical check-up. While these signs can be caused by non-cancerous conditions, it’s always better to rule out serious illness early.
