Question

What is the purpose of excision of the left external iliac, hypogastric, and obturator lymph nodes?

1) To remove cancerous lymph nodes
2) To treat lymphatic infections
3) To prevent the spread of lymphatic diseases
4) To improve lymphatic drainage

Answer 1

The excision of these specific lymph nodes is primarily done to remove cancerous nodes, aiming to halt the spread of cancer within the lymphatic system.

Step-by-step explanation:

The purpose of excising the left external iliac, hypogastric, and obturator lymph nodes is primarily to remove cancerous lymph nodes. Lymph nodes function as filters of the lymph system, trapping debris and pathogens, including cancer cells. Surgery is a common method to treat isolated solid cancers, and it can involve removing both the tumor and the local lymph nodes to prevent the spread of the disease. By removing these nodes, medical professionals aim to ensure that cancer cells do not disseminate further into the lymphatic system or the rest of the body.
