Tobacco and Cancer: A Deadly Link You Can't Ignore

Tobacco use is the leading cause of preventable cancer deaths worldwide. Whether it is
smoked or chewed, tobacco contains harmful chemicals that damage DNA and lead to the
development of cancer. According to WHO, tobacco is responsible for more than 8 million
deaths each year, and a large number of these are cancer-related.



How Tobacco Causes Cancer


Tobacco contains over 70 known carcinogens. These toxic substances enter the bloodstream and
reach every part of the body, not just the lungs or mouth. Here’s how it causes cancer:



  • Cell Damage: Carcinogens in tobacco damage the DNA in your cells.

  • Inflammation: Tobacco use promotes chronic inflammation, which helps
    cancer cells grow.

  • Immune Suppression: Tobacco weakens the immune system, making it harder
    to fight cancer cells.



Cancers Caused by Tobacco Use


Tobacco use is linked to various types of cancer, including:



  • Lung cancer

  • Mouth and throat cancer

  • Esophageal cancer

  • Pancreatic cancer

  • Bladder and kidney cancer

  • Cervical cancer

  • Stomach and liver cancer

  • Blood cancers like leukemia


Even passive smoking (second-hand smoke) can cause lung cancer and other health complications
in non-smokers.



Warning Signs to Watch For


If you use tobacco, look out for the following symptoms:



  • Persistent cough or hoarseness

  • Mouth sores that do not heal

  • Difficulty swallowing

  • Blood in urine or sputum

  • Unexplained weight loss

  • Lumps in the neck or body


Early detection is key. If you experience any of these signs, consult an oncologist
immediately.



Take the First Step Towards a Tobacco-Free Life



Quitting tobacco significantly reduces your cancer risk, even if you’ve been using it for
years. There are support programs and medications available to help you quit.


If you or a loved one has been diagnosed with cancer, choosing the right hospital matters.
