someone you know has just been diagnosed with stage 3 lung cancer. explain what this means in terms of treatment and prognosis

When lung cancer reaches stage 3, the cancer has spread to other cells and the lymph nodes. The prognosis (or five year survival rate) is 36%. As far as treatment goes, if the doctor is unable to remove the tumor they will recommend chemotherapy treatments. Chemotherapy and radiation treatments are often paired together for these treatments as well.

The alveoli are what give the lungs so much space, and if they are big, there is more gas exchange than if they are small.

Yes but it depends where you want to go
