1.1 Summary and Aims

According to Cancer Research UK, 1 in 2 people born after 1960 will be diagnosed with a form of cancer in their lifetime. Every two minutes someone is diagnosed with cancer. Every four minutes someone dies from cancer.
Above are some hard-hitting facts about cancer; it is rare to have not known anyone in your lifetime who has contracted the disease.
Because cancer is so prominent and deadly, it is understandable why a lot of research is undertaken into the causes and the process of cancer. Understanding the manner in which tumours invade and destroy normal tissue in the body, could lead to more efficient treatments and improve the results for those who have suffered the disease. Biologically experimenting

Despite cancer being a very mysterious and misunderstood disease, scientists have discovered certain behaviours that all of the forms display – these are referred to as Hallmarks.
Tissue Invasion and Metastasis is the sixth Hallmark on this list – Metastasis is the ability cancer possesses which allows the disease to spread.
During the growth of a cancer, the tumour will produce cells that are able to leave the original cluster to invade nearby tissues and form new groups; once these new groups are complete they are referred to as metastases.
These cells are able to leave the tumour by hijacking normal bodily processes in order to spread and settle at a new foundation.
Many cancerous tumours contain stem cells in them, meaning that these stem cells could potentially migrate from the original tumour, completely new tumours could be formed at a different origin. Worryingly it only takes as little as one of these cells in order for a new tumour to begin growth.
Early research believed metastasis was one of the final stages of cancer growth, however it is now believed it can happen any time during the process; a development researchers would like to stop as quickly as possible.

    A Harvard University researcher, Dr. Judah Folkman, pursued an indication made by many oncologists (researchers of cancer). This indication being that when removed from the primary tumor, the secondary tumor habitually begins to grow at quite a shocking rate. Dr. Folkman then rationalized that the primary tumor may be producing a certain substance that restrains the growth of the secondary tumor.…

    Normal cells are governed by the body systems and have limited life spans but eventually cease growing and dividing then die. Cancer cells are usually immortal, having an unlimited lifespan, constantly growing and dividing. Cancer cells experience anaplasia, the absence of differentiation, causing disorganization in size and shape, mutating them from the normal cells of the body. Cancer can grow rapidly or slowly, progressing from normal cell tissue to neoplasm. Cancer forms a sequence of cellular and tissue changes progressing from dysplasia to carcinoma in situ and then to invasive cancer. Presence of anaplastic cells and loss of normal tissue architecture signify the development of cancer. This progression is easily seen in the squamous epithelium. The high rate of cell division, local mutagens, and inflammatory mediators all contribute to the accumulation of genetic abnormalities that lead to cancer. The mutation of these cells can happen at a chromosomal or genetic level and once it happens it can continuously happen as that originally mutated cell divides (cancer stem cell), making other cells…

    The place where cancer starts to grow is called the primary site. Although some cancers may spread to more than one area of the body to form multiple secondaries or metastases. In order to spread, some cells from the primary cancer must break away, travel to another part of the body and start growing there. Cancer cells don't stick together…

    Cancer is caused by abnormal behaviour in cells, so it's helpful to understand the difference between a healthy cell and a cancerous cell. Cancer cells are set apart by a few characteristics, including unchecked growth and reproduction. Healthy cells will stop reproducing when they receive signals from nearby cells to do so; cancer cells no longer respond to these signals. Most cells will also cease dividing and reproducing if there's an error in their DNA (known as a mutation). Cancerous cells, by contrast, reproduce despite the damaged DNA and take on powers of immortality instead of dying off. And, finally, while healthy cells will stay put, cancerous cells will move randomly around the body, spreading cancer and making it more difficult to treat. If the reason behind why cancer cells do this would be known, a cure for cancer could be made: the chemical that causes the cancer cells to react could be avoided, and therefore cancer would…

    Based on the data gathered from observation differences in normal cells and cancerous ones have revealed themselves. Most notably in normal cells is there’s much less multiplying and a more even spacing among the cells. One of the fundamental characteristics of cancer cells is their uncontrolled growth and through the microscope this behavior is seen in an increased rate of cell division and in the failure of tumor cells to die (Cancer, 2011) Having unlimited growth means that cancerous cells could potentially invade everywhere in your body causing fatal complications.…

    Despite advances in treatment and care the public continues to have a great deal of anxiety and fear when diagnosed with cancer. Partially because people do not understand what having cancer means. Every living organism is made up of cells. These cells divide at a controlled rate with a specific function and multiply to replace damaged cells. While cancer cells grow and multiply with no control, destroying healthy cells in its’ path, and ultimately invading parts of the body inhibiting its’ function. Biologists have labeled cancer cells as any invading cell that can control proliferation and differentiation. Proliferation is the lifecycle of normal cells, to include regeneration of new cells as cells die. One of the phenomenon’s of normal proliferation is that the cells remain in their territory and do not inhibit cellular growth to surrounding cell membranes (Lewis, 2007). Differentiation is when a stem cell is coded to perform a specific function and under normal conditions these cells are unable to change their function. However, cancer is able to alter these naturally occurring processes. Cancer begins are a mutation in replicating DNA, either by genetics or a chemical, radiation, or viral exposure. The mutated DNA then starts proliferation and develop mutated…

    Everyone goes through suffering at some point in life. Some suffer from diseases and physical pain, while others suffer from emotional and mental pain. Sometimes, the suffering stops, in others it just keeps on going. As stated by Jimmy Whales, the founder of Wikipedia, “suffering is an individual's basic affective experience of unpleasantness and aversion associated with harm or threat of harm.” In other words, no one likes to suffer, yet, when life makes you, there is nothing you can do about it. In the play, “Death of a Salesman,” by Arthur Miller, Biff Loman, Willy Loman’s son suffers the most from Willy’s illusions and imaginations by having Willy lack parental guidance since the beginning, Willy thinking appearance in the key to success,…

    Cancer is a term used for diseases in which irregular cells divide without any control and have the capability to penetrate and infect normal body tissue through the blood and lymph system. Cancer is the second leading cause of mortality in the United States, exceeded barely by heart disease. According to the CDC Cancer Statistics and Data, there were more than 1.45 million people diagnosed with various kind of cancer between 1999 and 2007 and out of those more than 562,000 people died due to cancer (cdc.gov, 2012). Currently there are more than 200 different types of cancer that have been discovered. Cancer could be developed in any organ of the body. There are more than 60 different organs in the body where cancer cells can form and invade body tissues. While the origin of several cancers remains unknown, there are several cancers that are caused due to various reasons like exposure to chemicals, great alcohols intake, smoking, atmosphere poisons, sunlight disclosure, inherited, radiations, and illness. This paper will talk about the approach to, diagnosing of and staging of cancer, as well as the symptoms, side effects of treatment, and methods used to diminish physical and psychological effects of cancer and treatment.…

    Because the term “cancer” encompasses a broad range of diseases, diagnosing this disease will vary according to the affected tissues or regions from which it originates. According to Webster’s, the definition of cancer is “a malignant tumor of potentially unlimited growth that expands locally by invasion and systemically by metastasis.” It is this unlimited growth and the subsequent invasion of healthy tissue that makes cancers so deadly and aggressive treatment so vital.…

    Although all equal to the importance of current USA, the original 13 colonies had many differences, but more importantly, had much in common. England was mainly responsible for developing the 13 colonies. One of the first English attempts at an American colony was in 1607 by a group of English settlers, led by John Smith. They created the Jamestown colony in what we now know as Virginia. Surrounding colonies of Virginia include Maryland, Virginia, North Carolina, South Carolina, and Georgia and all makeup the Southern Colonies. Some of the most fertile land was apart of the Middle Colonies, which included Pennsylvania, New York, New Jersey, and Delaware. The New England Colonies included the colonies of Connecticut, Rhode Island, Massachusetts, and Province of New Hampshire.…

    Cancer, known medically as a malignant neoplasm, is a large group of different diseases, all involving unregulated cell growth. In cancer, cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. The cancer may also spread to more distant parts of the body through the lymphatic system or bloodstream. Not all tumors are cancerous. Benign tumors do not grow uncontrollably, do not invade neighboring tissues, and do not spread throughout the body.…
