Understanding the Causes of Lung Cancer

Lung cancer can develop due to a variety of factors. Here’s an overview of some common causes and risk factors:


Smoking is the leading cause of lung cancer, accounting for approximately 85% of cases. The carcinogens in tobacco smoke damage lung cells, leading to abnormal cell growth. Both long-term smokers and those exposed to secondhand smoke are at high risk.

Secondhand Smoke

Even if you don't smoke, prolonged exposure to secondhand smoke can significantly increase your risk of developing lung cancer. Inhaling the smoke exhaled by smokers or from burning tobacco products introduces harmful chemicals into your lungs.

Radon Gas

Radon is a naturally occurring radioactive gas that can accumulate in homes, particularly in basements and lower levels. It's the second leading cause of lung cancer, responsible for about 10% of cases. Radon exposure is particularly hazardous because it's invisible and odorless, making it difficult to detect without proper testing.

Asbestos and Other Carcinogens

Occupational exposure to asbestos and other harmful chemicals such as arsenic, chromium, and nickel can increase lung cancer risk. These substances can cause lung damage and cellular mutations over time. Workers in construction, manufacturing, and mining industries are particularly vulnerable.

Genetic Factors

Family history and genetic predisposition also play a role in lung cancer development. Certain genetic mutations can increase susceptibility to lung cancer, even among non-smokers. These genetic factors can interact with environmental exposures to heighten the risk.

Air Pollution

Prolonged exposure to high levels of air pollution, especially in urban areas, has been linked to an increased risk of lung cancer. Fine particulate matter and other pollutants can damage lung tissue over time.

Previous Lung Disease

Individuals with a history of lung diseases such as chronic obstructive pulmonary disease (COPD) or tuberculosis have a higher risk of developing lung cancer. These conditions can cause long-term inflammation and damage to lung tissues, creating an environment conducive to cancer development.

Understanding these factors can help in recognizing symptoms early and taking preventive measures. Our AI-powered Symptom Checker assists in identifying potential lung cancer causes based on your symptoms, guiding you toward the next steps for further evaluation and treatment.

Treatment Options and When to Seek Medical Advice

Lung cancer treatment varies based on the stage and type of cancer. Here’s an overview of common strategies:


Removing the tumor surgically is often the first line of treatment for early-stage lung cancer. This may involve removing a small section of the lung (wedge resection), a larger portion (lobectomy), or an entire lung (pneumonectomy).

Radiation Therapy

High-energy radiation is used to kill cancer cells or shrink tumors. This is often employed when surgery is not an option, or to destroy any remaining cancer cells post-surgery. It can also be used to relieve symptoms in advanced stages.


Drugs are used to destroy cancer cells, often in combination with other treatments. Chemotherapy can be administered orally or intravenously and is typically used for more advanced cancers or when cancer has spread to other parts of the body.

Targeted Therapy

These drugs target specific genes or proteins that contribute to cancer growth. Targeted therapy can be more effective and cause fewer side effects compared to traditional chemotherapy.


This treatment boosts the body’s immune system to fight cancer. Immunotherapy has shown promise in treating advanced lung cancer by helping the immune system recognize and attack cancer cells.

Palliative Care

For advanced lung cancer, palliative care focuses on providing relief from symptoms and improving quality of life. This can include pain management, nutritional support, and emotional counseling.

When to Seek Medical Advice:
If you experience persistent coughing, chest pain, shortness of breath, coughing up blood, or unexpected weight loss, it’s crucial to consult a healthcare professional immediately. These symptoms may indicate lung cancer or other serious conditions that require prompt attention. Early detection significantly improves treatment outcomes.

The Docus AI Symptom Checker is your first step toward understanding your lung health by identifying symptoms and potential causes. This tool can guide you in deciding whether you need to seek immediate medical attention, helping you take proactive steps for your health.
