Skin Changes
Look for:
Changes in moles (size, shape, color)
Yellowing or darkening of skin
Sores that don’t heal
6. 
Difficulty Swallowing or Eating
Trouble swallowing or persistent indigestion can signal throat, esophagus, or stomach cancer.
7. 
Frequent Infections
Getting sick often may indicate weakened immunity, sometimes linked to blood cancers.

Changes in Bowel or Bladder Habits
Watch for:
Long-term constipation or diarrhea
Painful urination
Changes in stool size or color

Persistent Cough or Hoarseness
A cough that lasts more than 3 weeks or voice changes can be a warning sign of lung or throat cancer.
10. 
Lumps or Swelling
Any new lump (breast, neck, armpit, or elsewhere) should be checked by a doctor.
Important Reminder
These signs don’t always mean cancer, but they should never be ignored—especially if they last more than 2–3 weeks.
Early detection can save lives. If you notice any of these symptoms, consult a qualified doctor promptly.
