Cellular Structure, Function, And Organization

The cell is the basic unit of life. Cellular structure, function, and organization are imperative factors to its existence. At the microevolutionary scale, the dynamically collaborative coordination of cell proliferation exists to maintain the social controls of beings (1Alberts, p. 1205). The expression, response, signaling, and survival of normal human cells allows for the progression of mankind. Nevertheless, on a constitutional level, mutations in the body allow for a vast range of genetic possibilities to transgress among multicellular organisms without much integrity. A mass of tumors may ultimately lead to uncontrolled, malignant growth from such abnormal cells known as the merciless disease of cancer. Taking into consideration…show more content…
Invasions result in the destruction of healthy tissue among one’s central physique. Moreover, such invasive cells may even allow for the generation of capillary blood vessels from those that are existing as a source for their survival through the process of angiogenesis. The tissue and/or organ in which the tumor has derived from or originated allows for cancer classification and characterization. Derived from epithelial cells, carcinomas exist to be one of the most common forms of cancer that lead to mortality. For instance, the primary tumor that arises among the breast is also known as breast cancer, while metastatic cells derived from the female reproductive organ would be classified as gynecologic/ovarian cancer. Rather than by mere unfortunate chance, the metastasis of tumor cells is conceived by way of its growth environment and cell interactions. Among the most prevalent cancer incidences amidst women, these forbidding diseases arise typically on account of inherited genetic mutations [in BRCA1/BRCA2], as well as through the inevitable process of aging. According to I.J. Fidler and J.J. Killion’s research article “Immunobiology of Cancer Metastasis,” it is believed that a multitude of biological factors including “the display of cell-surface receptors, enzymes, karyotypes, cell morphologies, growth properties, sensitivities to various therapeutic agents” allow for the progression of tumor growth throughout the human body (215).
