Question

which of the following statements is true of leukemia?
leukemia causes blood cells to be malformed.
leukemia affects blood or bone marrow.
leukemia is a type of bone cancer.
leukemia prevents blood cells from carrying oxygen.

Explanation:

Leukemia is a cancer that affects blood - forming tissues, including the bone marrow. It is not a bone cancer (so the statement “Leukemia is a type of bone cancer” is false). While some blood disorders can cause malformed blood cells (e.g., sickle - cell anemia), leukemia is mainly about the abnormal production of white blood cells in the bone marrow. And it is not directly about preventing blood cells from carrying oxygen (that is more related to disorders like anemia).

Answer:

Leukemia affects blood or bone marrow.
