Is small bowel lymphoma curable?

Yes, but: Yes, lymphoma can be cured, especially if diagnosed and treated appropriately/early enough. Cure in cancer typically means cancer free for 5 years, and not forever. The success rate depends on the type of cancer and stage(how advanced it is) at the time of diagnosis. I know this is vague, but hope it gives you some answer.. Good luck.

It is rare as: Hens teeth, hard to diagnose, but cure rates depend on its size, location, spread to nodes or extra-nodal tissues. At presentation, may need a surgeon, but the curative treatment usually depends on the way it looks under the microscope, its markers, and chemo- bio- therapy.
