The rate of mutation /genetic change is constant during tumor progression D. Nutrition/diet may effect rate of tumorigenesis E. All cells within a tumor are biologically equivalent and equally capable of high levels proliferationarrow_forwardWith regard to cancer cells, which of the following are true? A. Cancer cells are clonal, meaning that they are derived from many different cells that all underwent the same clonal mutation. Cells usually accumulate many mutations over time, and this results in cancerous growth. B. Almost all cancers are caused by oncogenic viruses. no Benign tumors are dangerous because they can easily invade surrounding tissue and spread to other locations in the body. DE. Cancer cells are unable to control their division.arrow_forward
- Which of the following accurately compares tumor suppressor genes and proto-oncogenes? A. Both tumor suppressor and proto-oncogenes prevent the spread of cancer by targeting and destroying existing cancer cells. B. A person who has both tumor suppressor and proto-oncogenes will always develop cancer. C. Proto-oncogenes code for growth factors, while tumor suppressor genes inhibit cell division of damaged cells.
