Tobacco is a known enemy of human health, responsible for a significant portion of cancer cases worldwide. Whether smoked or chewed, tobacco increases the risk of several types of cancer. Dr. Rajib Bhattacharjee, a renowned oncologist in Kolkata, emphasizes the importance of understanding the link between tobacco and cancer and taking actionable steps to reduce its devastating effects.
How Tobacco Causes Cancer
Tobacco contains thousands of chemicals, many of which are carcinogenic (cancer-causing). The most harmful substances include nicotine, tar, carbon monoxide, and benzene. When tobacco is smoked or chewed, these chemicals enter the body, causing genetic damage to cells. Over time, these damaged cells can multiply uncontrollably, leading to cancer. The process may take years, but the risk increases significantly with prolonged use.
Cancers Linked to Tobacco Use
- Lung Cancer:
- Smoking is the leading cause of lung cancer, accounting for 85% of cases. The harmful chemicals in tobacco directly affect the lungs, damaging their delicate tissues and leading to tumor formation.
- Mouth and Throat Cancer:
- Smokeless tobacco (chewing tobacco) is a significant cause of oral cancers, including cancers of the mouth, throat, tongue, and lips.
- Esophageal Cancer:
- Smoking and chewing tobacco both increase the risk of esophageal cancer due to prolonged exposure to harmful chemicals that irritate the esophagus.
- Bladder Cancer:
- Chemicals from tobacco are absorbed into the bloodstream and filtered by the kidneys into the bladder, where they damage bladder cells over time.
- Pancreatic Cancer:
- Both smoking and smokeless tobacco are associated with a higher risk of pancreatic cancer.
- Stomach and Colon Cancer:
- The carcinogenic substances in tobacco can affect the gastrointestinal tract, increasing the risk of stomach and colon cancers.
The Role of Passive Smoking
Even if you don’t smoke, being around tobacco smoke (secondhand smoke) increases your risk of developing cancer. Passive smoking is known to cause lung cancer and can increase the risk of other cancers, especially in non-smokers who live with smokers. Children and spouses are particularly vulnerable to the harmful effects of secondhand smoke.
Preventive Measures: Taking Action Against Tobacco
Dr. Rajib Bhattacharjee emphasizes that the most effective way to reduce cancer risk is to quit tobacco. Here are steps to take action:
- Quitting Smoking:
- Quitting smoking at any stage dramatically reduces the risk of cancer. Within just a few years of quitting, the body starts to heal, and the risk of developing tobacco-related cancers decreases.
- Avoiding Secondhand Smoke:
- Stay away from environments where smoking is prevalent. Secondhand smoke is also harmful and poses a significant risk, especially for children and pregnant women.
- Routine Screenings:
- Early detection is crucial in cancer prevention. For smokers and former tobacco users, routine screenings such as lung CT scans, oral cancer exams, and other diagnostic tests can detect cancers early, improving treatment outcomes.
- Healthier Alternatives:
- Embrace healthier lifestyle choices such as maintaining a balanced diet, exercising regularly, and avoiding all forms of tobacco use.
- Support for Quitting:
- Seeking professional help to quit tobacco is one of the most impactful steps you can take. Various programs, medications, and counseling services are available to help individuals overcome tobacco addiction.
