Positive growth factors play an active role in improving host metabolism, and then promote the ability to receive the operation and chemotherapy. However, there are many problems concerning their security. They are able to keep tumor cells survive and proliferate which can increase the number of s-phase cells and the expression of some cancer genes (c-myc, etc).
