Sally Has a Tumor

Question

Sally has a tumor. In an effort to fight the cancerous cells her body increases the production of
A) neutrophils.
B) NK cells.
C) suppressor T cells.
D) memory B cells.
E) plasma cells.

Accepted Answer

NK cells, or natural killer cells, are a type of immune cell that plays a role in fighting cancer cells. They can recognize and kill cells that are infected with a virus or have become cancerous. Neutrophils, suppressor T cells, memory B cells, and plasma cells are important components of the immune system, but they do not play as significant a role in fighting cancer cells as NK cells do.
