Cancer was a major problem in the medical field. Most cancer patients died, and the most important reason was that after chemotherapy, the body's immune system would be damaged. How could they recover so easily?
Another thing was that no one could predict whether the place where cancer cells used to grow would no longer house cancer cells when new cells regenerated.
Once the cancer cells grew again and reached a certain number, they would multiply rapidly in the human body.
This was also why it was not easy to get a tumor, but once you got one, it could quickly cause death in a very short period of time, especially in the later stages of cancer.
As Nuannuan performed acupuncture on Feng Shengxuan to kill the cancer cells in his body, she finally understood all that.
