[|Human|] My father is 83 and has had previous large b cell lymphoma that he recovered from. the other day during a scan by his heart m.d. a large mass showed up on his liver. he has had nausea and vomiting the last several weeks. he was told he has lymphoma again and a biopsy of his liver is to be done next week. What is the possible prognosis and survival rate. Thanks so much!!!
[|AI|]  Thanks for your question on Chat Doctor. Lymphomas have two phases in all patients. 1. Remission2. Crisis. Your father is having crisis phase right now. Appearance of new lesion in liver indicates worsening of disease. And biopsy is must. Usual five year survival with B cell lymphoma is 60%. And life expectancy is at least 4-5 years with regular chemotherapy sessions. So start chemotherapy again and continue with maintenance therapy for better life expectancy.
