Not all cancers of lung will spread. But if the cancer does spread there are certain areas of the body that it is more possible to go to. The most common areas for lung cancer to spread to are the lymph nodes, the liver, the bones, and the brain. Seeing as the cancer tends to spread or metastasize very early after it forms, it is a very serious cancer and one of the most complicated cancers to treat.
Symptoms of metastatic lung tumors rely on the location and size. Approximately 30%-40% of people with cancer of lung have a number of symptoms or signs of metastatic disease. Metastatic lung cancer in the liver typically does not cause symptoms, minimally by the time of diagnosis.
Cancer of lung can spread locally. It might grow into an airway, or into the chest wall or lining of the lung. Specialists consider it as advanced if you have fluid collecting around the lung and the fluid has cancer cells. This situation is named a pleural effusion.
Advanced (or metastatic) lung cancer indicates the cancer has spread from where it begun in the lung. Your cancer might be advanced when it is first diagnosed. Or it may return some time after you are first treated.
Cancer spread to the liver might lead to pain in your right side, just under your ribs. Or you might feel sick, mainly after eating rich food. A later symptom is frequently jaundice – the whites of your eyes and your skin may look a bit yellow. Your doctor could test how well your liver is working with a blood test. The most common test to take a look at the liver is an abdominal ultrasound.
