Final answer:
Identifying cell-surface antigens is important in diagnosing and treating lymphoma because the immune system uses antigens to distinguish between self and non-self and to launch immune responses.
Step-by-step explanation:
The subject of this question is Biology. Identifying cell-surface antigens is important in diagnosing and treating lymphoma because the immune system uses antigens to distinguish between self and non-self and to launch immune responses.
Cancerous cells often change their cell-surface antigens, and the immune system can identify and destroy these cells. Additionally, the presence of specific cell-surface antigens can help physicians identify cancer cells and determine the specific subtype of cancer, which can guide treatment options.
