Recently led to a product called Immunocal by an RN who claims it has helped members of her family withj their cancer. My wifes oncologist has no opinion either way and the group feels that if it keeps the cancer at least busy then her chemotherapy will be more effective. We began this progam 7 days ago. Draw your own conclusions about use. I initially looked to Chinese medicine but am afraid of the interraction between chemo and the herbs used.
