Metastasis occurs when lung cancer spreads from its original location to other parts of the body. This happens when cancer cells break away from the primary tumor, enter the bloodstream or lymphatic system, and travel to new locations where they form additional tumors. When lung cancer spreads, the new tumors are still considered lung cancer cells, even if they're found in other organs.
The most common places lung cancer spreads to are the bones, brain, adrenal glands, liver, and distant lymph nodes. It can also spread from one lung to the other. About 50% of lung cancers have already metastasized by the time they're diagnosed. This is because symptoms often don't appear until after the cancer has spread. When metastasis occurs, it's considered stage 4 lung cancer, which may require changes to treatment plans.
If you experience new or worsening symptoms, especially severe pain in specific areas, it's important to seek medical attention right away. Your healthcare team can use various imaging tests like PET scans, CT scans, or MRIs to check for metastasis and adjust your treatment plan accordingly.
