Your concern is quite natural and understandable. And hyou are right, lymphoma is not the worst news in the world. However, the best news in the world is that you have a very good chance of beating it if need be, and not just living a long time with it. The first thing to look into is finding a way to beat it that does not rely on the failed mainstream treatment methods of trying to cut away, burn away or poison away the symptoms of cancer - such as tumors, malignant lymph nodes, cysts and other cancer cell masses. That does nothing to address the underlying causes that let cancer gain a foothold and will do little or nothing to prevent it's return - and in fact may do just the opposite due to the damage left behind in the wake of cutting on the body, removing needed lymph nodes or other needed body parts, and damage to major organs and the immune system from radiation and/or chemo.
I suggest reading the following:
Modern Medicine versus Nature in Treating Cancer
A Natural Anti-Cancer Protocol
Moderm medicine has had over half a century of failure in the war on cancer. Nature has been there all along - just not patentable or profitable for mainstream medicine and the pharmaceutical companies.
Those who think otherwise, let me ask you when did God (or Nature if you prefer) become a quack?
