Symptoms depend on where the tumour and metastases are located. Lung cancer typically spreads to other parts of the lungs, and to the bones, liver, and brain. Read on for more information about the most common symptoms caused by metastases. Physical symptoms most commonly experienced by those with lung cancer include shortness of breath, coughing, and pain.
Shortness of breath and other respiratory symptoms
Shortness of breath and coughing are often caused by tumours in the lungs, concurrent chronic obstructive pulmonary disease (COPD), or a build-up of fluid around the lungs. Fluid from around the lungs (the pleura) can sometimes be removed either with a one-time procedure using a small catheter, or repeatedly, with a more permanent drainage catheter (a thin tube). Sometimes radiation therapy can be used to shrink tumours, while endoscopic procedures may relieve obstruction of the airways.
The most effective medicines include morphine or other opioids; some patients also find inhaled bronchodilators (medicines that widen the airways) beneficial. Other things that may be helpful include correct breathing technique and position, physical therapy exercises, and producing a stream of air (for example, by using a fan). Coughing up blood (haemoptysis) can often be relieved either with medication or with radiation therapy.
Pain
The patient may experience pain as lung cancer progresses into the chest wall, the bones, or other organs.
Bone metastases tend to cause pain, especially when moving, whereas those in the chest wall often cause pain when the patient is breathing deeply. Opioids, as well as many other kinds of pain medication, provide effective pain relief. Radiation therapy is helpful especially in the case of pain caused by bone metastases, as well as some other situations. In addition, non-medication pain management methods should be applied as well.
Symptoms caused by metastases in the liver
In many cases, individual metastases in the liver don’t cause any major symptoms. Symptoms usually appear once there is a large number of metastases and liver function starts to suffer. A common symptom experienced at this point is increasing fatigue. Corticosteroid medicines may be helpful.
Brain symptoms
Brain metastases cause symptoms such as headaches, nausea, and various neurological symptoms including vision problems, loss of balance, and paralysis. These symptoms can be relieved with corticosteroid medicines and radiation therapy. If the cancer is in the early stages, surgery might also be an option.
Psychological strain
Feelings such as anxiety and depression are understandable and fairly common symptoms in those with lung cancer. Time, talk support, and presence offered by both the care staff and the patient’s loved ones can support the patient, even during a bad day. Psychological symptoms can also be managed with medication. Treating these symptoms is especially important because they can make shortness of breath as well as other physical symptoms worse. Peer support may also be helpful.
