Hi, Thanks for writing in. Cancer in brain and lung is an advanced or stage 4 cancer. In this stage, the survival of a patient is maximum up to 2 years under best treatment and supportive care. Since he has ten tumors in various places, it will be best to provide him with supportive care. Pain relief is the most important concern right now. He must be provided with a pain relief combination that will reduce his pain and discomfort. He can be given higher pan relief medicines and that can be taken when required. Since he also has brain tumors, it cn cause indesired brain swelling that will lead to discomfort symptoms and this might require measures to reduce brain edema or swelling. Brain swelling is suspected if he has headaches, vomiting, nausea, dizziness among other symptoms. If there has been enough chemotherapy and radiation that he has received with persisting progression of disease then the expected surviva might vary from 6 months to a year with good supportive care. Please do not worry.
