The symptoms of metastatic lung cancer depend on the location of the metastasis and the extent of the spread to other organs in the body. Many times patients experience no symptoms even though tests have revealed advanced lung cancer. The most common areas for lung cancer to metastasize are the opposite lung, chest lymph nodes, liver, adrenal glands, the bones, and the brain. As metastatic lung cancer develops, some symptoms may arise.
Jaundice is a condition that can occur if a tumor blocks the common bile duct. This blockage may lead to yellowing of the skin and eyes, darker urine, and lighter stool. It is typically associated with metastatic lung cancer in the liver.
Pain in the backbone, thighs, or ribs is a common symptom of metastases in the bones. Many patients find this pain difficult to describe. Lung cancer that has spread to the bones can also lead to fractures.
Lung cancer can often times invade the adrenal glands. When this occurs, the patient can experience easy bruising and muscle weakness. Patients may also find themselves feeling weaker and wanting more sleep.
If lung cancer spreads to the nervous system, it may cause several symptoms. Unsteadiness, headaches, altered motor function and seizures may occur as a result of metastases in the brain.
