Lung Cancer: Understanding the Disease
Lung cancer is a type of cancer that begins in the lungs. It is the leading cause of cancer death for both men and women worldwide. Each year, more than 220,000 people are diagnosed with lung cancer, and over 150,000 people die from the disease.
Risk Factors
The most common risk factor for lung cancer is smoking. Other risk factors include:
- Exposure to second-hand smoke
- Asbestos exposure
- Radon exposure
- Family history of lung cancer
- Certain genetic mutations
- Certain occupational exposures, such as exposure to arsenic, chromium, nickel, and vinyl chloride
Symptoms
The early symptoms of lung cancer are often vague and may not be noticeable. As the cancer grows, it can cause more noticeable symptoms, such as:
- A persistent cough
- Chest pain
- Shortness of breath
- Wheezing
- Unexplained weight loss
- Fatigue
- Coughing up blood
Diagnostic Tests
If you have any symptoms of lung cancer, it is important to see a doctor right away. The doctor will perform a physical exam and ask about your medical history. They may also order one or more of the following tests:
- Chest X-ray
- CT scan
- MRI scan
- PET scan
- Bronchoscopy
- Biopsy
Treatment Options
The treatment for lung cancer depends on the stage of the cancer and the patient's overall health. Treatment options may include:

- Immunotherapy
- Targeted therapy
Side Effects
The side effects of lung cancer treatment can vary depending on the type of treatment received. Common side effects may include:

Follow-Up and Outcomes
After treatment, it is important to have regular follow-up appointments with your doctor. These appointments will help monitor your health and detect any recurrence of the cancer early. The survival rate for lung cancer depends on the stage of the cancer at the time of diagnosis. For early-stage lung cancer, the survival rate is about 50%. For late-stage lung cancer, the survival rate is about 10%.
Prevention
