To summarize: The roles of proto-oncogenes, oncogenes, and tumor suppressor genes in carcinogenesis. Introduction: Cancer is caused due to abnormal cell growth. This occurs due to several genetic and epigenetic alterations that cause uncontrolled proliferation of cells. The clinical manifestations of cancer are numerous and depend on the variety and intensity of symptoms. The word tumor is used to refer swelling, but now it is used to describe the new growth or neoplasm (cancerous growth).

What are biofertilizers and mention the significance

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
