What does coughing blood mean with lung cancer?

When someone has been living for over 2 years with lung cancer, what does it mean when the patient starts coughing up blood? The doctor says there’s nothing they can do.
Tapestry6, I didn’t ask about the symptoms of lung cancer. That’s all you gave.
Just so you know, it’s not me that has cancer, but someone close to me. It is quite advanced, but somehow she keeps going on. Incredibly strong, and doesn’t seem to want to give up. She sometimes improves enough to be able to go for a short walk outside, but this isn’t often.

In my case (Metastatic Kidney cancer that mestastisized to the lung) hemoptasis (sp: coughing up blood from the lungs) meant the cancer was growing near one of the bronchi and that one or more the inferior blood vessels the cancer creates for itself has failed and is bleeding into the bronchi.

This can be remedied, at least temporarily, by an embolization of the bleeding vessels, or a bronchoscopy where they will use a laser to cauterize the bleeding vessels.

Not an MD, just a patient.
