Cancer is one of India's most pressing health challenges, and early detection can dramatically improve survival rates. If you're in Kolkata or West Bengal, understanding the warning signs of cancer is critical. Many people dismiss early symptoms, only to discover cancer at advanced stages when treatment options are limited.
This comprehensive guide covers the early warning signs of various cancer types specific to your region, what you should watch for, and where to seek expert care from the best oncologist in Kolkata for prompt diagnosis and treatment.
Why This Matters for You: Early detection increases survival rates from 30% to over 90% depending on cancer type. Knowing what to watch for could literally save your life.
Part 1: Common Early Signs of Cancer
Unexplained Weight Loss
One of the first warning signs many cancer patients report is sudden, unexplained weight loss—typically 10 pounds or more without trying.
What it means: Cancer cells consume energy rapidly, causing rapid weight loss despite normal eating habits.
When to be concerned: If you lose more than 5% of your body weight in 6 months without diet changes, consult a doctor immediately. Contact the best cancer hospital in Kolkata for evaluation.
Persistent Fatigue
Extreme tiredness that doesn't improve with rest is a red flag often overlooked.
Why it happens: Cancer produces substances that disrupt your body's energy production. Chemotherapy and radiation also cause severe fatigue.
Action to take: If fatigue persists beyond 2-3 weeks, seek evaluation from an experienced oncologist in Kolkata.
Persistent Cough or Hoarseness
A cough lasting longer than 3 weeks, especially if you don't have a cold or flu, warrants investigation.
For lung cancer: Cough may produce blood-tinged mucus. This is a serious sign requiring urgent attention.

Skin Changes
Monitor for:
