Lung cancer commonly metastasizes (spreads) to various organs and tissues in the body. The most common sites for metastasis in lung cancer include:
1. **Lymph nodes:** Lung cancer often spreads to nearby lymph nodes in the chest, including those in the mediastinum.
2. **Liver:** The liver is a common site for metastasis in many types of cancer, including lung cancer.
3. **Bones:** Lung cancer can spread to bones, leading to bone pain and an increased risk of fractures.
4. **Brain:** Metastasis to the brain is relatively common in lung cancer. Symptoms may include headaches, seizures, and neurological deficits.
5. **Adrenal glands:** Lung cancer may metastasize to the adrenal glands, which are located on top of the kidneys.
6. **Other lung:** Metastasis can occur in the other lung, leading to the development of additional tumors.
7. **Kidneys:** Although less common, lung cancer can spread to the kidneys.
8. **Pancreas:** Metastasis to the pancreas is less common but can occur.
9. **Skin:** Skin metastases are rare but can manifest as lumps or nodules on the skin.
The likelihood of metastasis depends on the type and stage of lung cancer. Advanced stages of lung cancer are more likely to have spread to distant organs and tissues. It's important to note that early detection and treatment can improve outcomes and reduce the risk of metastasis. If someone has been diagnosed with lung cancer, their healthcare team will closely monitor for signs of metastasis and tailor treatment accordingly.
