All About Lung Cancer

Lung cancer remains one of the most common and deadliest cancers worldwide. Increased awareness about this disease, its causes, and prevention can help individuals recognize early symptoms and seek timely medical advice. 

What is Lung Cancer?

Lung cancer is a type of cancer that starts in the lungs, where abnormal cells grow uncontrollably and can form tumors. These cells can potentially spread to other body parts (metastasize), making the disease harder to treat. There are two main types of lung cancer:

  • Non-Small Cell Lung Cancer (NSCLC): The most common form, accounting for 80-85% of cases. It includes subtypes like adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.
  • Small Cell Lung Cancer (SCLC): Less common but more aggressive and likely to spread faster. SCLC is mostly linked to smoking.

Lung cancer accounts for 12% of all cancer diagnoses but leads to over 18% of all cancer deaths globally.

Who is at Risk? 

Several factors increase the risk of developing lung cancer. Some key risk groups include:

  • Smokers and Ex-Smokers: Around 85% of lung cancer cases are linked to smoking, although non-smokers can also develop lung cancer.
  • Family History: Individuals with a family history of lung cancer are more susceptible.
  • People Exposed to Secondhand Smoke: Even non-smokers regularly exposed to secondhand smoke have a 20-30% increased risk.
  • Occupational Exposure: People exposed to asbestos, radon, or other harmful substances at work have a higher risk of lung cancer.
  • Individuals with Previous Radiation Therapy: Those who have had chest radiation therapy, particularly for other cancers, may be at higher risk.

If you fall into any of these risk categories, getting screened can make a crucial difference in detecting lung cancer early. Click here to get yourself screened. 

Places at Risk 

Air quality significantly impacts lung health. Here’s a quick look at how air quality indexes (AQI) in different regions contribute to lung cancer risk:

  • High-Risk Areas: Cities with consistently high pollution levels (AQI over 150) — like Delhi, Beijing, and Lahore — see an elevated risk of lung conditions, including cancer. 
  • Rural Areas with Specific Pollutants: Some rural areas may have poor air quality due to industrial plants, pesticides, or biomass burning, all of which emit carcinogenic compounds.
  • Indoor Air Quality: Many cases of lung cancer are connected to radon exposure in homes. Radon is an odorless gas released from soil and rocks that can accumulate indoors.

Monitoring local AQI and taking precautions on high-pollution days is crucial, particularly for those at higher risk.

Does Vaping Cause Lung Cancer?

The long-term impact of vaping on lung cancer risk is still under study, but here’s what we know so far:

  • Chemical Exposure: While vaping does not produce tar-like cigarettes, many e-liquids contain potentially harmful chemicals, such as formaldehyde, which has carcinogenic properties.
  • Nicotine Addiction: Some vape products contain nicotine, which may not directly cause cancer but can increase the likelihood of addiction, which is a risk factor for lung-related diseases.

Prevention Tips

Reducing your risk of lung cancer involves a combination of lifestyle choices and proactive measures:

  • Avoid Smoking: The most effective way to prevent lung cancer is to avoid smoking or quit if you currently smoke. Even long-term smokers see health benefits after quitting.
  • Avoid Exposure to Radon: Test your home for radon and use ventilation systems to reduce radon exposure if levels are high.
  • Reduce Exposure to Carcinogens: Minimize exposure to harmful substances like asbestos and certain chemicals in industrial settings.
  • Stay Physically Active: Regular exercise helps improve lung function and overall health.
  • Monitor Air Quality: On days when the AQI is high, especially if it’s over 100, try to stay indoors or wear masks when going outside.

  • Early Detection: When detected early, the 5-year survival rate for localized lung cancer is around 60%. However, most cases are diagnosed at advanced stages, with a 6-8% survival rate.
  • Gender Difference: Men are generally at higher risk, but cases among women have been increasing due to smoking and environmental exposures.
  • Screening Impact: Regular screening of high-risk individuals can reduce mortality by up to 20% by catching the disease at earlier stages.

Lung cancer is a severe disease with a high mortality rate, but awareness and proactive health measures can make a difference. Reducing exposure to risk factors, monitoring air quality, and staying informed about early symptoms are critical. And for those at higher risk, remember to get tested immediately through reliable health services, to ensure timely detection and intervention.
