Reduced lymphocyte levels would be the most plausible explanation for the rapid spread of malignant tumors. Lymphocytes are a type of white blood cell that play a key role in the immune system's response to cancerous cells. When lymphocyte levels are reduced, the body may not be able to effectively identify and target cancer cells, allowing them to spread more quickly. Cortisol and oxytocin levels are hormones that are associated with stress and social bonding, respectively, but they are not directly involved in the immune system's response to cancer. NK cells (natural killer cells) are a type of lymphocyte, but having an elevated count of NK cells is not necessarily a protective factor against cancer.
