The human body is endowed with a special trait: a uniqueness and distinction from one person to another. Unfortunately, this condition does not give it any upper hand to diseases and disorders it experiences in a lifetime. In this case, all persons possess a general outline of disease process. This is regardless of the magnitude of the disease, disorder or dysfunction. Generally diseases are caused by toxins from either outside the body or inside because of its own reactions and those of the bacteria in it.
Apart from these causes, there exists other more case specific disease pre-disposing factors. These are genetic and environmental conditions. This research paper explores the link between genetic predisposition and environmental conditions that trigger the onset of breast cancer. Breast cancer is the second killer of all forms of cancer after lung cancer (Walker, 2001). For a long time, this disease has been viewed as an all female affair but this misconception has long been challenged by growing cases of male infections.Causes of Breast Cancer Sample
What exactly is breast cancer and what causes it? Cancer, the deadly killer is a genetic disease caused by mutations within a genome leading to development of tumor suppressor genes (TSGs) that in return cause proliferation of cells in opposite ways. Body organs grow by the multiplications of cells at different rates depending on the body organ (Servan, 2008). This process is controlled by genes that are entrusted with the role of coding for proteins that accelerate or decelerate the rate of replication. Mutated genes contain abnormal genetic material that translates into non-functional products causing the cells to multiply uncontrollably. In breast cancer, a mutant inactivation of TSGs leads to a proliferation of cells that form a hard mass of tissue on the breast. The tumor can be felt on self-examination.
