Can other cancers metastasize into lung cancer?

Other cancers may also metastasize to lung cancer, such as gastrointestinal cancer, bone cancer, ovarian cancer, etc. Therefore, in the early stages of lung cancer, treatment should be carried out, which can be mainly surgery, supplemented by radiotherapy and chemotherapy to improve the quality of life. After the cancer cells spread, a combination of treatment methods should be adopted.

Lung cancer is a malignant tumor. As we all know, it is divided into four stages. Generally, in the fourth stage, the treatment effect is often not very good, which is very harmful to the patient's body and mind. In fact, it is not only the primary tumor that is terrible, but the metastasis of other cancers is even more terrible and takes longer to treat. So can other cancers metastasize into lung cancer?
The relationship between lung cancer and other cancers <br/>As people smoke more and more, or are exposed to radiation or drink more frequently, normal cells will mutate, and after multiple mutations, cancer will occur. Cancer cells will proliferate indefinitely, and compared with their homologous normal tissues, their adhesion is reduced, so they are prone to metastasis. When cancer cells metastasize to a specific location, they will not affect other organs. For example, breast cancer will metastasize to the lymph nodes or lungs and liver. Lung metastasis comes from breast cancer, gastrointestinal cancer, bone cancer, ovarian cancer, kidney cancer and lung cancer.
Treatment of lung cancer
1. Surgery <br/>Surgery is a common method to remove the tumor and nearby lymph nodes with negative margins. If the tumor is close to the middle of the chest cavity, a complete resection is required. Doctors will generally preserve lung function as much as possible so that the patient can eat and digest food.
2. Radiotherapy <br/>Radiotherapy is also a common method. First, it is used for auxiliary treatment. Second, when the patient is tolerant of surgery, radiotherapy is used to kill cancer cells in the body. Note that this method will also kill normal cells, so nutritional supplements are needed after radiotherapy.
3. Chemotherapy <br/>Chemotherapy uses drugs to kill cells. If you take the drugs regularly, it can improve your quality of life and prolong your survival.
4. Targeted therapy <br/>Targeted therapy is a symptomatic treatment method. Commonly used drugs include bevacizumab, erlotinib, and gefitinib. Generally, first-line drug resistance is relatively strong, so second- and third-line drugs are needed.
5. Immunotherapy <br/>This method uses drugs to enhance immune function. Because during radiotherapy, the body's resistance is greatly reduced, so more immunity is needed to support it.
