Since the early 1970s, incidence rates for non-Hodgkin’s lymphoma have nearly doubled. Incidence rates for Hodgkin’s disease have declined about 60%. Better means of diagnosis has also increased the number as doctors better understand cancer of lymphocytes verses other diseases.
To put your mind at ease, please err on the side of caution and see your doctor. It was approximately 2 to 3 months in between my daughter's bouts of grossly swollen neck glands. She was diagnosed with Low Grade B-Cell Malt Lymphoma after two bouts of swollen neck glands and diffuculty swallowing. She was first given two rounds of antibiotics by her priamary physician and then saw an ENT who prescribed steroids to shrink her grossly swollen sublingual tonsils. That treatment was also ineffective so the ENT took a biopsy of the sublingual tonsils. That is when she was diagnosed with lymphoma.
