What Is Stage IV Lung Cancer With Anaplastic Lymphoma Kinase (ALK) Rearrangement?
This type of lung cancer is rare, and it often happens to people who aren't smokers. Although there isn't a cure, there are treatments for it that can slow down your cancer and help you feel better.
"Stage IV" means that the cancer has spread beyond the lung where it started. It may be in your other lung, too, or in the fluid around your lungs, or somewhere else in your body.
The "ALK rearrangement" part of the name is about a gene called ALK. If you have this type of lung cancer, your ALK gene got rearranged and joined with another gene. This causes cancer cells to grow and spread.
