In general how large would the lymph node swelling be in cases of hodgkin's disease. i've heard it can be as little as an inch on nodes of neck?

The size may vary: As a rule, the larger , the more and the harder the nodes are, the more chances of them to be malignant. But anything is possible so don't rely on the size alone. Only a biopsy can confirm a diagnosis of lymphoma. Fever. Night sweats and weight loss indicate a more advanced stage. Take care!

Any size: Hodgkin's disease can cause lymph node enlargement of any size. I have seen conglomerations of lymph nodes fill over half of the chest, and I have seen tiny lymph nodes (the size of a pea.).
