To answer the question and pose a hypothesis, we must first understand the fundamental difference between normal and cancer cells: cancer cells do not mature, do not age, and do not undergo cell death like normal cells do. Aging is the deterioration of functions over time,…
As a female child ages into a woman, the hips gradually become broader to permit the mature female to carry the growing fetus in her womb. The breasts become well-developed to allow her to provide the best nutrition possible once she delivers the conceived child. And since each multicellular organism is a composite of many cells, what we see happening to it is a reflection of what is happening inside the body, within the cells.
The aging process of a multicellular organism such as a human is a reflection of division, development, and programmed cell death of its somatic cells. For a cell, the earliest physiological process to disappear once it is developing is its ability to produce daughter cells. Because once a cell is developing, it steps out of the cell cycle and enter a nondiving state, the Go phase. Most of the cells in a developed human body are in Go. Most common examples of these are the specialized neurons, which do not divide (Campbell and Reece, 2002, p. 226). So on the onset of life, a fertilized egg cell divides into many, and will be grouped according to what their functions will be once they develop defining characteristics that make them different from others.
However, normal cells cannot multiply forever. Not only will development not permit them, as is the case once a cell dies before the organism, but mortality is engraved in the DNA. Since DNA replication mechanism only makes a daughter strand by adding nucleotides at the 3’ end, its 5’ end, which an RNA primer filled during the course of DNA replication, is left unfilled once the primer is removed, and the resulting DNA is shorter after every replication. The good thing is, the 5’ ends of DNA strands, called telomeres, do not actually code for a gene and are thus dispensable. But since telomeres are of defined length, DNA replication and cell division can only go through a defined number of cycles as well (Campbell ...

As genes are the basic control machine of the cells, alteration of any kind may bring devastating consequences, or malignancy. When compared with the normal cells, where damage of any kind is taken care by the repair system, tumor cells do not have any repair mechanism for the damaged DNA and there is a constant proliferation of cells without displaying senescence, hence, generating a series of abnormal cells, with altered cellular pathways for uncontrolled proliferation, figuring malignant tumors (Alberts et al., 2007; Katzang et al., 2009).
Over the last several decades, an increase in the incidence of these cancers has been observed which has several implications for the health care system, as these cancers are not only associated with significant morbidity and mortality but also pose an economic burden since they incur enormous health care related costs.
Even though scientists and medical researchers have been searching for a cure for cancers, it is hard to pinpoint the cause due to the fact that some cancers can be caused by genetic factors, while others are caused by environmental factors; some just occur randomly.
Another way that healthy cells differ from cancer cells is that healthy white blood cells can detect damaged cells, such as viruses, and attack them, stopping them before they spread the virus to the rest of the body. Cancer cells, however, can pass through this system without being detected, which means that the immune system is not notified to their presence (Skehan 15).
There are several reasons why a person is inflicted with this disease though a very definitive cause has not been established for all cancers and it is also known that not all forms of tumors are malignant and dangerous. When cancer really spread in the body, they may also enter through the lymphatic system or bloodstream to sites other than the major organ where these cells lie (Cairns et al 2011).
Physicians in those early days may not have known what the condition was, but they knew that something destructive was taking place. Unfortunately, breast cancer was considered a taboo, more of a punishment than an uncontrollable illness, which meant that very few diagnoses were made before the individual succumbed to the devastation of cancer.
This situation is called metatsic cancer of the lungs. It is considered one of the fatal cancers among all the other types of cancers. Just like any other types of cancer, lung cancer can spread to other parts of the body. Furthermore, lung cancer
This paper concerns the observing and studying with the revolutionary prospectus in pharmaceutical perspectives, snake venom could pay the way for the fresh age of medicines, as well as the research for treatment of cancer among other illnesses. Snake venoms are often studied by scientists and researchers for its therapeutically/remedial application.
