Question from Salad Eater: What happens if I lose lymph nodes to surgery or my white count drops dramatically because of chemotherapy? Is my immune system weakened, and will I become vulnerable again to cancer and infection?
Answers - Marisa Weiss, M.D. There are many hundreds of lymph nodes throughout the body. When some are removed from under the arm during breast cancer surgery, usually lymph nodes in the surrounding areas pick up the slack. These days, there is a tendency to take out as few lymph nodes as possible to avoid disruption of lymph fluid drainage, as well as to keep your immune system as undisturbed as possible. Yes, chemotherapy does reduce immune cell count. Standard dose chemotherapy drops the count down only temporarily. Almost always, your body is able to recover completely within a short period of time. Bone marrow transplant patients, a procedure used mostly in the past, did knock down your immune count beyond what your body could normally recover from. That is why, after the chemotherapy was all finished, you needed to transplant new bone marrow cells back into your body. These are the cells that make your blood count. But a low immune cell count does not increase your risk for recurrence of cancer.
