⚠️ None of these signs mean someone has cancer — they can be caused by many harmless conditions — but they do deserve medical attention if they are persistent, new, or unexplained.
🛑 15 Common Cancer Warning Signs
1. Unexplained Weight Loss
Losing weight without trying (10+ pounds) can be an early sign of cancers such as pancreas, stomach, lung, or esophagus.
2. Persistent Fatigue
Not normal tiredness — but exhaustion that doesn’t improve with rest.
3. A Lump or Thickening Under the Skin
Breast, testicular, and soft-tissue cancers often begin as painless lumps.
4. Changes in Skin or Moles
Watch for:
-
new moles
-
changes in shape/color
-
bleeding or itching
-
irregular borders
5. Persistent Pain
Pain that doesn’t go away may signal bone, ovarian, or other cancers.
6. Persistent Cough or Hoarseness
A cough lasting more than 3 weeks or a raspy voice may indicate lung or throat cancer.
7. Difficulty Swallowing
Called dysphagia — can be related to esophageal, throat, or stomach cancer.
8. Unusual Bleeding or Discharge
Including:
-
blood in urine
-
blood in stool
-
vaginal bleeding after menopause
-
bloody sputum
9. Changes in Bowel or Bladder Habits
Lasting more than a few weeks:
-
chronic constipation
-
diarrhea
-
narrower stools
-
difficulty urinating
10. Non-healing Sores
A sore in the mouth that won’t heal can indicate oral cancer
— especially in smokers or heavy drinkers.
11. Persistent Heartburn or Indigestion
Long-term reflux that doesn’t respond to treatment can signal stomach or esophageal cancer.
12. Night Sweats (Severe)
Unexplained drenching sweats can be a symptom of some blood cancers.
13. Frequent Infections or Fevers
Blood cancers like leukemia may show up as:
-
repeated infections
-
persistent low-grade fevers
14. Swollen Lymph Nodes
Especially if:
-
painless
-
firm
-
present for more than 2–4 weeks
15. Unusual Bruising
Especially tiny dots (petechiae) or easy bruising can relate to blood cancers.
🟢 Important Notes
-
These signs do not mean someone has cancer.
-
Most are more often caused by non-cancerous conditions.
-
What matters is persistence, change, or symptoms that are new and unexplained.
🧠 When to See a Doctor
You should get evaluated if:
-
A symptom lasts more than 2–3 weeks
-
A lump grows or changes
-
You experience unexplained bleeding
-
Something “just feels wrong”
Early diagnosis makes treatment far more effective.
