Study Notes
What is Lung Cancer?
- Lung cancer is a serious disease that occurs when harmful tumors grow and spread in the lungs.
- It happens when cells in the lungs get their jobs mixed up and create cells that hurt the body.
- Lung cancer can be caused by smoking tobacco, exposure to secondhand smoke, asbestos, radon, and genetic reasons.
Causes of Lung Cancer
- The most common cause of lung cancer is smoking tobacco, responsible for about 90% of cases.
- Exposure to secondhand smoke increases the chance of getting lung cancer.
- Asbestos and radon are dangerous substances found in nature that can cause lung cancer.
- Genetic reasons, such as a family history of lung cancer, can increase the chance of getting it.
Signs of Lung Cancer
- Early signs of lung cancer may not always be present, but common symptoms include:
- Hoarse voice
- Trouble swallowing
- Wheezing
- Headache
- Chest pain
- Cough
Treatment Options for Lung Cancer
- Treatment options depend on the size and location of the tumor.
- Common treatments include chemotherapy, radiation, and surgery.
- Chemotherapy uses drugs to kill cancerous cells, but can cause side effects like sickness and hair loss.
- Radiation uses x-rays to shrink or remove the tumor, often recommended for early-stage cancer.
- Surgery involves removing or shrinking the tumor, and is sometimes offered as a treatment option.
