What stage of lymphoma is indicated by swollen lymph nodes in the right axilla and right side of the neck?

Swollen lymph nodes in the right axilla and the right side of the neck indicate a specific pattern of lymphatic involvement that corresponds with Stage II lymphoma. In Stage II lymphoma, the disease is localized to two or more lymph node regions on the same side of the diaphragm. In this scenario, the right axilla and right side of the neck both represent lymph node areas that are affected by the disease, and since they are on the same side of the diaphragm, it confirms that the lymphoma is categorized as Stage II.

In contrast, Stage I would involve involvement of a single lymph node region, while Stage III would indicate lymph node involvement on both sides of the diaphragm. Stage IV represents widespread involvement, often including extralymphatic sites. Thus, the description of swollen lymph nodes in two areas on the same side of the diaphragm aligns with the characteristics of Stage II lymphoma.
