Stage 2 and 3 lymphoma refer to the different stages of non-Hodgkin lymphoma, which is a type of cancer that affects the lymphatic system. Stage 2 lymphoma is also known as intermediate-grade lymphoma, and is characterized by having a higher rate of growth and spread than stage 1 lymphoma. It is also more likely to cause symptoms, such as enlarged lymph nodes, fever, night sweats, and fatigue.
Stage 3 lymphoma is also known as high-grade lymphoma, and is considered more advanced than stage 2. It is characterized by having an even higher rate of growth and spread than stage 2, and is more likely to cause symptoms such as fever, night sweats, weight loss, and fatigue. It is also more likely to have an aggressive response to treatment.
In summary, the key difference between stage 2 and stage 3 lymphoma is that stage 3 lymphoma is more advanced than stage 2, and is associated with a higher rate of growth and spread, as well as more severe symptoms. As such, it is generally more difficult to treat and requires more aggressive treatment.
