Final answer:
Hodgkin lymphoma is diagnosed through an excisional biopsy and staging tests. Treatment involves chemotherapy and radiation therapy. The cure rate is 90% for stage I or II.
Step-by-step explanation:
Hodgkin lymphoma is a cancer that affects the lymphatic system. The best test to diagnose Hodgkin lymphoma is an excisional biopsy, which involves surgically removing a lymph node or a piece of a lymph node for examination. To determine the extent of the disease, staging tests such as CT scans or laparoscopy may be performed. The treatment for Hodgkin lymphoma typically includes a combination of chemotherapy and radiation therapy. If the disease is diagnosed at stage I or II, there is a 90% cure rate.
