Lung metastasis is cancer that started in another part of the body and spread to the lungs. Lung metastasis is not the same as cancer that starts in the lung called primary lung cancer. Some kinds of cancer are more likely to spread to the lung than others.
Lung metastases are cancerous tumors that start somewhere else in the body and spread to the lungs. Metastatic tumors in the lungs are cancers that developed at other places in the body or other parts of the lungs. They then spread through the bloodstream or lymphatic system to the lungs.

Although it can spread anywhere, breast cancer spreads to the bones in nearly 70 percent of people with metastatic breast cancer, estimates the Metastatic Breast Cancer Network. Other common sites are the lungs, liver, and brain. About 6 to 10 percent of breast cancers in the United States are diagnosed at stage 4.
At the U-M Rogel Cancer Center, treatment of bone metastasis takes place in the clinic where the originating cancer is treated. For example, if prostate cancer has metastasized into the bone, it is treated in the Urologic Oncology Clinic. Call the Cancer AnswerLine at for help finding the clinic you need.
Instead, a tumor might be first discovered on an imaging study done as part of treatment follow-up, such as a chest CT computed tomography scan.

If your doctor suspects lung metastasis, he or she is likely to order imaging tests such as a chest CT or a PET positron emission tomography scan.

Breast cancer has been confirmed by gene expression analysis to be a heterogeneous disease 12 that may be divided into biologically distinct subtypes. In clinical practice, the cancer subtype is determined using immunohistochemistry 34 and a therapeutic plan is designed according to the subtype 5. Lung metastasis is commonly observed in breast cancer patients at the time of relapse.
What does it mean if your breast cancer spreads metastasizes to your lungs? What kind of symptoms might you expect, and what treatments are available? Whether you're worrying that your cancer may have spread, or if you've learned that it has, you probably have a lot of questions.
