The immune system is unable to fight and kill those tumor cells
that have suppressed the expression of MHC class I molecules that
specialize in presenting endogenous antigens on their cell
surface.
The human immune system plays a critical role in fighting
various types of cancer
The success of the immune defenses against infectious agents
depend on the ability to recognize these intruders as foreigners in
the human boy.

2.
How can one rationalize from an evolutionary perspective that
malignant cancer has the property, which sets it apart from most
other diseases, that it can only develop after cancer cells acquire
multiple different mutations in different genes?
Group of answer choices
If a single mutation could transform a normal cell into a
malignant cancer cells, animals with bodies consisting of a very
large number of cells would always die before reaching reproductive
age.
As a person gets older, the number of mutations gradually
increases, and so does the chance of developing cancer.
The development of malignant cancer involves mutations in both
oncogenes and tumor suppressor genes.
This statement is incorrect: most human diseases only develop
after multiple different mutations occur.
