In one or two, well-crafted paragraphs in your laboratory journal, summarize the process in which normal cells become cancer cells. your paragraph (s) must include each of the terms listed below. underline each term in your paragraph (s) : apoptosis blood vessels cell cycle cell division metastasis mutations oncogenes proto-oncogenes regulated signals tumor suppressor genes

In homeostasis fashion, cells undergo balanced cell division and programmed cell death (apoptosis) through regulated signalling. This maintains tissue integrity. On the one hand, Proto-oncogenes promotes cells proliferation. On the other hand, tumors suppressors inhibit cell growth and division especially in cells with damaged dna.

Therefore mutations on these oncogenes could result to uncontrolled cell proliferation. Cancer cells also overexpress angiogens that results to proliferation of blood vessels in tumors. This contributes to their metastasis in the body.
