How can the lymph system reduce the spread of cancer? a. by producing lymphocytes, which attack and kill cancer cellsb. by producing lymphocytes, which create antibodies against cancer cellsc. by producing lymph nodes, which attack and kill cancer cellsd. by producing lymph nodes, which create antibodies against cancer cells

The answer is; A

In the lymph vessels,  a few lymphocytes ‘ patrol’ the tissues as they scan for antigens. When they detect an antigen, including surface antigens of rogue cells (cancer cells), the antigen-presenting cells (APCs) present this to the cognate lymphocytes turning them to effector cells (such as effector T-cells). The effector T- cells bind to the cancer cells and induce apoptosis.
