yourself about lung cancer:
Metastatic cancer to the lung
Metastatic lung cancer is cancer that starts somewhere else in the body and spreads to the lungs.
See also: Lung cancer
Metastatic tumors in the lungs are malignancies (cancers) that developed at other sites and
spread via the blood stream to the lungs. Common tumors that metastasize to the lungs include
breast cancer, colon cancer, prostate cancer, sarcoma, bladder cancer, neuroblastoma, and
Wilm's tumor. However, almost any cancer has the capacity to spread to the lungs.
- Bloody sputum
- Shortness of breath
- Weight loss
- Rib cage pain
Note: Sometimes, there are no symptoms.
Exams and Tests
- Chest x-ray
- Chest CT scan
- Cytologic studies of pleural fluid or sputum
- Lung needle biopsy
- Surgical lung biopsy
In most cases, metastatic cancer to the lung is a sign that the cancer has spread into the
bloodstream. Usually cancer will be present even in places not seen by CT scans. In these
circumstances, removing the visible tumors by surgery is usually not beneficial. Chemotherapy
is usually the treatment of choice.
Cure is unlikely in most cases. Patients with testicular cancer or lymphoma, however,
have a higher likelihood of long-term survival and cure compared with those with most other
In some circumstances in which the primary tumor has been removed and cancer has spread
to only limited areas of the lung, the lung metastases can be removed surgically with the
goal of long-term survival or, occasionally, cure.
Radiation therapy, the placement of stents inside the airways, or laser therapy are sometimes
used but are less common than surgery or chemotherapy.
The stress of illness can often be helped by joining a support group where members share
common experiences and problems. For this condition, see cancer support group.
Living more than 5 years with metastatic cancer to the lungs is uncommon. Rarely, patients
with certain types of cancer (sarcoma, renal cell carcinoma, bladder cancer, colon cancer,
or melanoma) that has only spread a limited amount to the lung can be cured with surgery.
In some cases, cancer (particularly lymphoma or testicular cancer) that has spread to
the lung can be cured with chemotherapy. But in general, lung metastases are a sign of widespread
cancer with a poor survival rate.
- Side effects of chemotherapy and radiation therapy
- Further spread of the cancer
- Pleural effusions (fluid between the lung and chest wall),
which can cause shortness of breath
- Pericardial effusions (fluid around the heart), which
can cause shortness of breath
When to Contact a Medical Professional
Patients with a history of cancer who develop persistent cough, bloody sputum (coughing up
blood), shortness of breath, unexplained weight loss, or other significant changes in their
health should contact their health care provider.
Not all cancers can be prevented, but many can be by not smoking, eating a healthy diet,
exercising regularly, and keeping alcohol consumption moderate.
