New City Osaki Clinic homepage > Frequently asked questions > Question 5
Lymphocytes are damaged immediately after the treatment with anticancer agents or radiation therapy. When they are incubated, the efficiency in proliferation is very poor.
When the treatment schedule is available, we recommend that you have the blood necessary for at least about four times of administration collected and frozen for preservation before the treatment starts.
Some types of anticancer agents, however, do not influence the proliferation of lymphocytes. Please consult us.
