Cancer-Research Paper-Chapter 1

Cancer is an agent that causes deaths in a global level. Actually the health of the human is considered one of the most important factors in the growth and development on the population; this is the reason why many people want to save their health when cancer appears. Cancer consists in every malign and benign tumor; every single person has cancer cells, these cells do not appear in the standardanalysis (tests) until they have multiplied by billions. When a person has cancer it indicates the person has multiple nutritional deficiencies. These may be genetic, environmental, food or lifestyle factors. The investigation for this disease has taken place when the president of United States Richard Nixon had cancer, the investigation of cancer had begun and many technology invents came with it.After years of research, cancer can be cured with natural alternatives and synthetic treatments.

I. What is cancer?
There are many ways to defined cancer, but the National Cancer Institute of United States at the National institute of health, which is one of the most important institutes of cancer, tell us that cancer is a term used for diseases in which abnormal cells divide withoutcontrol and are able to invade other organs (tissue, cells). Cancer cells can spread to other parts of the body through the blood and lymph systems (Cancer Topics).
Jesse Stoff, MD, past editor of Journal of Anthroposophic Medicine and author of Chronic Fatigue Syndrome, said that the tumor is not a part of human organism, but represents a rebellion of the cells against the human organism.(17).
A. Types of cancer
Cancer is not only one disease, because cancer produces more diseases when it appears. There exist more than 100 different types of cancer. Cancers are named for the organ or type of cell in which they start for example, cancer that begins in the colon is called colon cancer; cancer that begins in basal cells of the skin is called basal cell carcinoma.There are many cancer’s types, but NCI grouped into broader categories. The main categories of cancer include: carcinoma, which is the cancer that begins in the skin or in tissues that line or cover internal organs; sarcoma: cancer that begins in bone, cartilage, fat, muscle, blood vessels and other tissues. Leukemia: cancer that starts in blood-forming tissue such as the bone marrow and causeslarge numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and myeloma: those are cancers that begin in the cells of the immune system and the central nervous system cancers: cancers that begin in the tissues of the brain and spinal cord (Common Cancer Types).
B. Origins of Cancer
All cancers begin in cells that are the body's basic unit of life. The body is made upcells; the cells grow and divide in a controlled way to produce more cells as they are needed to keep the body systems that controls our healthy, the cells are replaced with new cells, when they become old or damage (they died). However, sometimes this orderly process goes wrong.
The genetic material the DNA of a cell can become damaged or changed, producing mutations that affect normal cellgrowth and division. When this occurs, cells don’t die when they must do and new cells form when the body doesn’t need them.
The extra cells may form a mass of tissue called a tumor which continues to grow. As it grows, it may damage and invade nearby tissue. If a cancerous tumor outgrows its birthplace when it passes is called the primary cancer site and moves on to another place this iscalled the secondary cancer site, it's referred to as metastasizing. Not all tumors are cancerous; tumors can be benign or malignant. The benign tumors are not cancerous. They should often be removed, and, in most cases, they do not come back. Cells in benign tumors do not spread to other parts of the body; and the malignant tumors are cancerous. Cells in these tumors can invade nearby tissues...
