A nurse is caring for a client who is newly diagnosed with breast cancer.
The client asks the nurse, "What is the difference between benign and malignant tumors?" Which of the following statements should the nurse include in her response to the client?
Malignant tumors do not spread into, or invade, nearby tissues.
Benign tumors do not spread into or invade nearby tissues.
Benign tumors spread and invade nearby tissues.
There is no difference between benign and malignant tumors.
The Correct Answer is B
Choice A rationale
Malignant tumors do spread into or invade nearby tissues. This invasive nature allows cancer cells to spread to other parts of the body through the blood or lymph systems.
Choice B rationale
Benign tumors do not spread into or invade nearby tissues. They may grow larger but do not spread to other parts of the body. Benign tumors can be serious if they press on vital structures such as blood vessels or nerves.
Choice C rationale
Benign tumors do not spread and invade nearby tissues. This statement is incorrect and contradicts the true nature of benign tumors.
Choice D rationale
There is a difference between benign and malignant tumors. Malignant tumors are cancerous and invade nearby tissues, whereas benign tumors do not.

Correct Answer is D
Explanation
Choice A rationale
Tumor enhancer genes are not typically a recognized category in cancer genetics. Proto-oncogenes and DNA repair genes are relevant to cancer development.
Choice B rationale
This choice is incorrect as there are genes like proto-oncogenes, tumor suppressor genes, and DNA repair genes that play roles in cancer.
Choice C rationale
This choice is partially correct but incomplete without including DNA repair genes, which are also crucial in cancer prevention.
Choice D rationale
This choice is correct as proto-oncogenes can become oncogenes, tumor suppressor genes prevent uncontrolled cell growth, and DNA repair genes fix DNA mutations that can lead to cancer.
