“Doctor, is there a vaccine to prevent cancer?”
This is one of the most common questions patients ask.
👉 The answer is YES—but not for all cancers.
According to Dr. Deenadayalan T, some cancers are directly linked to infections, and these can be prevented through vaccination.

🧠 What is a Vaccine?
A vaccine is a medical injection that helps your body:
✔️ Build immunity
✔️ Fight specific infections
✔️ Prevent future disease
You’ve already seen this in childhood vaccines.
👉 The same concept applies to certain cancers caused by infections.
📊 The Shocking Truth: 15% of Cancers Are Preventable
Let’s break this down clearly.
👉 Out of 100 cancer cases, nearly 15 are caused by infections.
These infections come from:
- 8 viruses
- 3 parasites
- 1 bacterium
👉 That’s 12 microorganisms responsible for infection-related cancers.
Key point:
👉 This 15% is largely preventable.
🦠 Major Infections That Cause Cancer
Among all infection-related cancers, a few major culprits stand out:
1. Human Papillomavirus (HPV)
- Responsible for ~100% of cervical cancers
2. Hepatitis B & Hepatitis C
- Cause 50–75% of liver cancers
3. Helicobacter pylori (H. pylori)
- Causes ~90% of distal stomach cancers
👉 These few infections alone contribute to most infection-driven cancers.
⚙️ How Do Infections Turn Into Cancer?
It doesn’t happen overnight.
👉 These infections cause long-term (chronic) inflammation
Over time:
- Cells get damaged
- The body responds abnormally
- Pre-cancerous changes develop
- Eventually → cancer
👉 Chronic infection = long-term risk
💉 Which Cancer Prevention Vaccines Are Available?
Here’s the important part.
✅ Available vaccines:
✔️ HPV Vaccine
- Prevents cervical cancer
- Recommended for adolescents and young adults
✔️ Hepatitis B Vaccine
- Protects against liver cancer
- Part of routine immunization
👉 Currently, these are the most effective cancer-prevention vaccines available.
🚫 Important Reality Check
Let’s not oversell this.
👉 Not all cancers can be prevented by vaccines.
But:
👉 A significant portion CAN be prevented
👉 And that’s a huge opportunity most people ignore
🛡️ What You Should Do Now
Simple, practical steps:
✔️ Get vaccinated (HPV, Hepatitis B)
✔️ Follow healthy lifestyle habits
✔️ Go for regular health checkups
👉 Prevention is always easier than treatment.
⚠️ When to Consult a Doctor
If you are unsure about:
- Vaccination eligibility
- Cancer prevention
- Symptoms or risks
👉 Don’t guess—consult a specialist.
