"may have low grade lymphoma or maybe it was inflamed because of inflammation from my arthritis in my spine."

It seems that people are latching on to the "watch and wait" when, in lact's case, that has a meaning other than what we typically think of. This may simply be inflammation, which is drastically different than lymphoma. I sure hope for her sake that that is what she has. Let's not have her needing treatment at some future time, or a lifetime of monitoring, when that may not be the case.
