With this finding, it is imperative to learn about the complexities of the disease, including the causes and risk factors, pathology, clinical manifestations, diagnostic studies, and treatment modalities. Causes and Risk Factors Several causes have been attributed to cancer. It points out that there is no single factor that can cause cellular aberrations at the level of the lower gastrointestinal tract. Currently, medical research literature is saturated with its possible involvement in genetic, environmental, dietary, lifestyle, and overall health status. Some people are at increased risk because they have inflammatory bowel disease, a personal or family history of colorectal polyps or colorectal cancer, or genetic syndromes like familial adenomatous polyposis (FAP) or hereditary non-polyposis colorectal cancer (also known as Lynch syndrome) (“Screen for Life” 2). Advancing age is also a significant factor in the development of tumors that could later develop into colorectal cancer. Overall, 91% of new cases and 94% of deaths occur in individuals 50 and older. Based on the most recent data by the Surveillance Epidemiology and End Results (2008), the incidence rate of colorectal cancer is more than 14 times higher in adults 50 years and older than in those younger than 50. Furthermore, gender is considered as a risk factor for colorectal cancer. According to SEER (2008), colorectal cancer incidence and mortality rates are 35% higher in men than in women. The reasons why risk is higher for men than for women are not completely understood, but may reflect higher frequency of abdominal obesity, smoking, and drinking in men, as well as hormonal differences (American Cancer Society 3). In the same research data by SEER (2008), race also plays a role in the statistics of mortality rates in colorectal cancer. Colorectal cancer incidence and mortality rates are highest in African American men and women. Moreover, several studies have documented that African American patients are more likely to be diagnosed after the disease has spread beyond the colon. In addition, African Americans with colorectal cancer are less likely than white patients to receive recommended surgical treatment and adjuvant therapy (Du et.al. 2007). Nevertheless, having a past medical history of colorectal cancer is a significant finding in redeveloping the disease. Precancerous and cancerous tumors surgically removed can reemerge due to irritation in the area. Also, virtually not every tumor is removed in a single operation, and smaller tumors may grow after the removal of the larger and most obvious ones. Lifestyle- related factors, including physical inactivity, smoking, high fat diet, obesity, alcohol- intake are also significant factors in developing cellular and tissue malignancy aside from colorectal cancer. Pathophysiology Like any other types of cancer, alteration in the normal physiologic process in the lower gastrointestinal tract is the culprit of colorectal cancer. Deletion of genes is linked to the transformation of normal colon epithelial cells to benign and malignant adenomas. Normally, the cell regeneration rate should occur at a rate almost equal to cell death. However, mutations of tumor suppressors, oncogenes, and repair genes cause an increase of underdeveloped and undifferentiated cells transforming gradually into tumors and ...Download file to see next pagesRead More

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).

Cancer, also known as malignant neoplasm, the hallmark characteristic involves uncontrolled proliferation of cells. Under normal conditions cell grow, divide and die, but in cancer cells the defect takes place at the gene level leading to the formation of an abnormal DNA.

Pancreatic Cancer Research Paper
It is the fourth leading cause of cancer deaths in men and women. According to the American Cancer Society, nearly 43,920 new cases and 37,390 deaths will occur in the United States in 2012 as a result of pancreatic cancer. This disease has been increasing at a rate of 1.5% every year with a survival rate of only 4% in patients five years after diagnosis.

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).

The limited availability of the management options also add to the misery of medical physicians trying to combat with this deadly disease along with the patients. Much research has been conducted to understand the exact mechanisms involved in the development of malignant cells.

Thus, thyroid gland is vitally involved in the metabolic and growth regulation of the body (Norman, 2009). Thyroid cancer or carcinomas is rare however, its prevalence rates are increasing. Incidence: Research indicates about 75% of the population having thyroid nodules, yet not all nodules are cancerous.

The pathological findings sought to link the pathological data after death, to the patient’s illness. Consequently, it laid the foundation on the study of cancer known as oncology. However, it was the renowned surgeon known as John Hunter from Scotland who hypothesized that cancer could be cured through surgery.
