Can kidney cancer spread to the lungs?

Yes, kidney cancer can spread to the lungs, and this type of spread is called metastasis. When cancer moves from its original location to another part of the body, it's still considered the same type of cancer - so kidney cancer that has spread to the lungs is still treated as kidney cancer rather than lung cancer. This is an understandably concerning situation, and connecting with others in cancer support communities who have faced similar experiences can provide valuable emotional support alongside medical care.
