Question

question 7 of 10
some cancer treatments have a side effect of killing white blood cells. which best describes a person undergoing this treatment?
a. they would be more likely to be harmed by common bacteria.
b. they would be less likely to catch a cold or a flu.
c. they would have more lymphocytes than a normal person.
d. they would have better protection against viruses than bacteria.

Explanation:

White blood cells play a crucial role in the immune system. They help the body fight off infections, including those caused by bacteria. If a cancer treatment kills white blood cells, the body's ability to defend against bacteria is weakened. So, a person undergoing such treatment is more likely to be harmed by common bacteria. Option B is incorrect because a weakened immune system (due to fewer white blood cells) makes it more likely to catch colds or flu. Option C is wrong as the treatment reduces white blood cells (including lymphocytes). Option D is also incorrect as the overall immune - defense (against both viruses and bacteria) is compromised when white blood cells are killed.

Answer:

A. They would be more likely to be harmed by common bacteria.
