Introduction

Tobacco use remains one of the leading preventable causes of cancer worldwide. Millions of people continue to use tobacco in various forms despite growing awareness of its harmful effects. Whether smoked, chewed, or consumed in smokeless forms, tobacco exposes the body to numerous harmful chemicals that can damage cells and increase the risk of developing cancer.

According to global health studies, tobacco is responsible for a significant percentage of cancer-related deaths. The good news is that quitting tobacco can substantially reduce cancer risk and improve overall health.

What Is Tobacco?

Tobacco is a plant product containing nicotine, a highly addictive substance.

Common forms of tobacco include:

Smoking Tobacco

  • Cigarettes
  • Bidis
  • Cigars
  • Pipes
  • Hookah

Smokeless Tobacco

  • Gutka
  • Khaini
  • Zarda
  • Pan Masala with tobacco
  • Chewing tobacco

Regardless of the form used, tobacco exposes the body to harmful chemicals that can increase cancer risk.

How Tobacco Causes Cancer

Tobacco smoke contains thousands of chemicals, many of which are known carcinogens (cancer-causing substances).

These chemicals can:

  • Damage DNA
  • Cause genetic mutations
  • Promote abnormal cell growth
  • Trigger chronic inflammation
  • Weaken the body's natural repair mechanisms

Over time, repeated exposure can increase the likelihood of cancer development.

Cancers Linked to Tobacco Use

Tobacco is associated with multiple types of cancer.

Lung Cancer

Lung cancer is one of the most strongly tobacco-related cancers.

Smoking damages lung tissue and significantly increases the risk of developing lung cancer.

Common symptoms include:

  • Persistent cough
  • Breathlessness
  • Chest pain
  • Coughing up blood
  • Unexplained weight loss

Oral Cancer

India has one of the highest rates of oral cancer, largely due to smokeless tobacco use.

Risk factors include:

  • Gutka
  • Khaini
  • Tobacco chewing
  • Smoking

Symptoms may include:

  • Non-healing mouth ulcers
  • White or red patches
  • Difficulty swallowing

Throat Cancer

Tobacco use increases the risk of cancers affecting:

  • Throat
  • Voice box (larynx)
  • Pharynx

Symptoms may include:

  • Hoarseness

Esophageal Cancer

Smoking and tobacco exposure increase the risk of esophageal cancer.

Common symptoms include:

  • Difficulty swallowing
  • Weight loss

Bladder Cancer

Many people are unaware that tobacco use is a major risk factor for bladder cancer.

Cancer-causing chemicals from tobacco enter the bloodstream and are filtered through the kidneys into urine, affecting the bladder lining.

Pancreatic Cancer

Research has shown that smoking increases the risk of pancreatic cancer.

The risk generally rises with long-term tobacco exposure.

Kidney Cancer

Tobacco use is also associated with increased kidney cancer risk due to long-term exposure to harmful chemicals.

Cervical Cancer

Smoking may increase the risk of cervical cancer and may contribute to poorer outcomes in some patients.

Second-Hand Smoke and Cancer

Tobacco use does not only affect the smoker.

Second-hand smoke exposure may affect:

  • Family members

Passive smoking has been linked to several health risks, including increased cancer risk.

Protecting family members from tobacco smoke is an important preventive measure.

Smokeless Tobacco Is Not Safe

Tobacco and Young People

Nicotine addiction often begins at a young age.
