Air Pollution & Passive Smoking: Unveiling Lung Cancer Risks – Insights from Experts

November 24, 2024 Catherine Williams - Chief Editor Health

In 2022, there were 20 million new cancer cases globally, resulting in 9.7 million deaths. One in five people will develop cancer in their lifetime. The mortality rates are one in nine for men and one in 12 for women.

Insights from Oncologists on Lung Cancer

Oncologists Dr. Ankur Bahl, Dr. Devavrat Arya, Dr. Sajjan Rajpurohit, and Dr. Pooja Babbar shared their expertise on lung cancer detection, management, and treatment.

Risk Factors for Lung Cancer

  1. Air Pollution: Increases the risk.
  2. Passive Smoking: Connected to higher cancer rates.
  3. Lifestyle Changes: Important for reducing risk.

Preventative Steps

Dr. Ankur Bahl suggests several steps to lower lung cancer risk:

  • Quit Smoking: This is the most effective prevention method.
  • Healthy Diet: Eat fruits, vegetables, and whole grains. Limit processed foods and red meat.
  • Regular Exercise: Improves lung function and boosts immunity.
  • Limit Pollution Exposure: Use protective gear and ensure ventilation in polluted areas.
  • Avoid Radon: Test for radon in homes, especially in radon-prone areas.

Dr. Babbar recommends similar measures, highlighting the importance of avoiding smoking and getting regular health check-ups. For those at risk, screening options like low-dose CT scans may be advisable.

Types of Lung Cancer

Dr. Sajjan Rajpurohit explains the two main types of lung cancer:

  1. Small Cell Lung Cancer (SCLC):

    • Accounts for about 15% of lung cancers.
    • Grows rapidly and spreads quickly.
    • Often associated with smoking.
    • Treated mainly with chemotherapy and radiation.
  2. Non-Small Cell Lung Cancer (NSCLC):
    • Makes up 85% of lung cancer cases.
    • Grows more slowly.
    • Early detection allows treatment via surgery, chemotherapy, and newer targeted therapies.

Modern Diagnosis and Treatment

Dr. Ankur Bahl highlights advancements in lung cancer diagnosis and treatment:

  • Diagnostic Tools:

    • Low-dose CT scans: More effective than standard X-rays for early detection.
    • PET-CT scans: Help determine cancer extent.
    • Biomarker testing and liquid biopsies: Allow for personalized treatment.
  • Treatment Options:
    • Targeted therapy: Drugs targeting specific cancer mutations.
    • Immunotherapy: Boosts the immune system to fight cancer.
    • Robotic-assisted surgery: Minimally invasive with quicker recovery.
    • Stereotactic radiotherapy: Precise radiation treatment.

Signs and Symptoms of Lung Cancer

Dr. Babbar defines early lung cancer signs which may be mistaken for other conditions. Symptoms include:

  • Persistent cough that worsens.
  • Coughing up blood.
  • Chest pain.
  • Shortness of breath.
  • Hoarseness.
  • Unexplained weight loss or fatigue.

Recognizing these symptoms early can be crucial for effective treatment.
