Thank you for posting your query.
Based on the information you have provided, your brother in law seems to have cancer of the lung with metastases, where the cancer spreads to several other parts of body, usually through the blood.
This generally makes the prognosis for recovery poorer. I suggest you discuss this issue with his oncologist
Please get back if you require any additional information.
