The Pathology Of A Newly Diagnosed Cancer Patient Than The Well Differentiated Ones

Cancer is a defined as a group of cells in the body that begin to divide without stopping and

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

die. What is differentiation? Differentiation is when a cell stops dividing to perform a special function

Cell differentiation- All cells contain the same genes. Cell differentiation is the development of cells that become specialised for different functions. Cells that aren’t specialised can advance into specialised cells, this process is called cell differentiation and this can be seen in different organisms. Specialised cells can only be one certain gene and although genes for other specialists are present they are switched off.

Cancer is defined by the National Cancer Institute as ?the title given to a group of related diseases. All types of cancer are categorized by uncontrollable growth of cells that metastasize to surrounding tissues.? Cancer can develop at almost any part of the human body and anyone can develop cancer, although risk typically increases with age because most cancers tend to require many years to develop. ?Typically, human cells tend to grow and divide and ultimately form new cells as the body needs them. When an organisms cells grow old or get damaged, the cells die, and new ones replace them. However when cancer

Cancer is defined by the National Cancer Institute as the title given to a group of related diseases. All types of cancer are categorized by uncontrollable growth of cells that metastasize to surrounding tissues. Cancer can develop at almost any part of the human body and anyone can develop cancer, although risk typically increases with age because most cancers tend to require many years to develop. ?Typically, human cells tend to grow and divide and ultimately form new cells as the body needs them. When an organisms cells grow old or get damaged, the cells die, and new ones replace them. However when cancer develops, this orderly process gets reformatted. As cells increasingly get more irregular, old or damaged cells begin to survive when they should die, and new cells develop in the body when there is no need for them. These abnormal cells have the ability to divide without stopping and tend to result in growths called tumors?(cancer.gov). Cancerous tumors are defined as malignant meaning that they can spread to nearby tissues or metastasize to distant places in places within the body and form new cancerous tumors. There are over 100 forms of cancer and they are usually named after the organs or tissues where the cancers originate. Staging of cancer is used when describing the severity of a person?s cancer and is based upon the following

The difference between stem cells and a differentiated cell is the fact that stem cells have the ability to become any kind of cell once they are more developed. Differentiated cells already have a purpose set for them and will fulfill that one purpose once they have developed and matured fully. Stem cells are basically cells that haven’t differentiated yet. Stem cells are important to science because of their

The body is made up of hundreds of millions of living cells. Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person’s life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out or dying cells or to repair injuries. Cancer begins when cells in a part of the body start to grow out of control. There are many kinds of cancer, but they all start because of out-of-control growth of abnormal cell (American Cancer Society, 2010).

The type of cancer I chose to write about is called acute lymphoblastic leukemia. Acute lymphoblastic leukemia is developed through damaged bone marrow and blood cells. Stem cells form blood cells, these stem cells that form white cells start out as cells then generate into blast cells, or also known as lymphoblast. Lymphoblast then produce a cell a type of white blood cell known as lymphocytes. This damaged cell then becomes a leukemic cell and multiples into billions of cells leukemic lymphoblast cells. This then causes the number of healthy blood cells to drastically lower. The origin of the word "acute" comes from the fact that the disease progresses rapidly and creates immature blood cells, rather than mature ones. It also can be called acute lymphocytic leukemia. Acute lymphoblastic leukemia is a

Cancer is described in the Merrium-Webster dictionary as: a serious disease caused by cells that are not normal and that can spread to one or many parts of the body. That does not begin to describe the changes in the histology of the cell or to the body’s systems that cancer causes. Cancer is a small word that describes an all encompassing and ever changing disease. Neuroendocrine cancers are rare, so rare that there are only a handful of oncologists that specialize in them. (Newly…, n.d.) Carcinoid lung tumors are even more uncommon. How can science identify and treat a cancer so unique?

     The cells are then sent out to a laboratory for testing. This generally takes two weeks. Most labs use the Bethesda System SIL to measure the amount of cell changes, if any. This system measures “normal” at one end of the chart, to “invasive cancer” at the other end. Generally it is difficult to determine the stage or grade of cell changes which occur. This often means diagnosis and treatment are difficult to make. (623).

To perform this task, however, the cells must specialize by a process called cell differentiation. Cells that are

Tumor markers and cancers cells are both produced by cancer that is the tale tell sign for the appropriate diagnosis. Tumor markers can help detect, diagnose and treat certain kinds of cancer. Doctors will biopsy, measure and test tumors to discover whether or not it is malignant or benign (“Tumor Markers). Tumor markers can reveal the stage along with the prognosis of the patient. Tumor markers not the only sign that can be used to discover cancer in a patient. Circulating tumor cells is also a useful tool. It is defined by the CellSearch assay, that CTC is a cell that is “EpCAM positive, cytokeratin positive, CD45 negative, and nuclear stain positive (Zhao et al., 2013).”

Cell differentiations is how generic embryonic cells become specialised cells. This occurs through a process called gene expression which is a specific combination of genes that are turned on and off and this is what dictates how a cell functions. This is in order for the cell to perform a specific function. Cell differentiation is presented during multiple stages of development. During this process the cell size and shapes changes dramatically as its ability to respond to signaling molecules. Differentiated cells can be red and white cells, sperm cells, egg cells, bone cells, hair cells and muscle cells. Differentiated cells are specific to suit their function in the body and they work together in a particular organ or an organ system. Cell

There are various differences between cancerous and normal cells. Normal cells stop growing when enough cells are present; whereas in contrast, cancer cells do not stop growing when there are a sufficient number of cells. This can this can result in a tumor being formed. Cancer cells don’t cooperate with other cells as normal cells do. Normal cells respond to signals sent from other nearby cells. When normal cells receive these signals, they stop growing, cancer cells, however do not respond to these signals. When normal cells are damaged or get old they are either repaired or die. Cancer cells are either not repaired or do not undergo apoptosis. Another difference is the ability to spread, normal cells stay in a specific area of the body where
