Lymphadenectomy

Lymphadenectomy was the most energy-consuming part when operating on patients who were suffering from cancer.

Lymph nodes were part of the human lymphatic systems and were spread around various organs. Each lymph node was about the size of a grain of rice, and they were scattered loosely all over the human body. The number and position of lymph nodes varied between people.

We live in a world where some people are born with their hearts on the right side. When you take this into consideration, you can imagine how hard it was to clear all the lymph nodes with cancerous cells of a person's body. It was just like playing hide-and-seek.
