Does anyone know how serious lymphoma is as far as aggressive or if a person can recover with chemotherapy or just tell me more about it. My grandmother had a cancerous tumor in her stomach and she was 88 and she couldn't take the chemo anymore. It was really horrific to see. But she did get better and the tumor was down to the size of a nickel but she couldn't take it anymore at her age and when she stopped she didn't last very long. I think the chemo shortened her life by not finishing her treatments. But he is a good bit younger looks pretty healthy. I'm just wondering if it's something he can Live through or will eventually kill him down the road
