Lung metastasis is the spread of cancer to the lungs from any other part of the body. Due to the proximity of the lungs to the abdomen and the breast, breast and certain types of stomach cancers are primarily responsible for lung metastasis. The place where the cancer originates is called as primary cancer.
For example, if the cancer originates in the breast and spreads to the lungs, it is called as primary breast cancer with lung metastasis. At times, the primary cancer is very baffling and doctors cannot find out where the cancer initially originated. In such cases, the cancer is known as unknown cancer with lung metastasis.
Symptoms of Breast Cancer Metastisis To Lung
Once the cancer spreads to the lungs, the person begins to experience a persistent, racking cough that does not respond to medication. The cough only gets more and more severe with time.
Blood In The Sputum
The cough may also be accompanied by blood or blood in the sputum, which indicates the presence of cancer in the lungs. Coughing up blood can be very frightening and one tends to get confused whether the blood originates from the throat and lung passages or from the stomach.
Coughing up blood does not always indicate the presence of cancer but could also mean something else. However, it is wise to get yourself tested to be on the safer side. Lung cancer is one of the leading causes of coughing up blood.
However, people with severe infections are also known to cough up blood so it is better to simply consult your doctor.
Pain In The Chest
A chronic throbbing pain begins in the chest, shoulders and back when people are afflicted with lung cancer. This is true even in the case of metastatic lung cancer.
Shortness of Breath
As the metastatic lung cancer advances, the person may start to experience a shortness of breath and difficulties in breathing which is not relived through normal medication and may become more profound with the passage of time. This happens because of excessive fluid build up in the lungs due to the spread of the cancer.
Weakness and Weight Loss
Like any other cancer, metastatic lung cancer can lead to general malaise, fatigue, weakness and weight loss. In case the cancer has spread, this feeling of weakness only gets exacerbated. There may also be a loss of appetite and in inability to carry out or perform routine activities.
Metastatic lung cancer is very difficult to treat. While some of the tumours from the lungs can be removed through surgery and chemotherapy, the cancer has spread to other organs also and becomes very difficult to eliminate.
The person may have to undergo years and years of drug therapy and chemotherapy and still not remain cancer free. Metastatic lung cancer has a poor prognosis especially when it is detected late and has a very low survival rate.
