The human body is an amazing system consisting of more than 60,000 billion cells. These cells make up the organs in our body and each cell will live different lengths of time, being about four months on average for red blood cells, and over a year for white blood cells. In order for our body to keep living, each cell multiplies into two cells before it dies. However, sometimes the cell won’t properly divide and die, which can cause many problems, including cancer. So what exactly is causing the cells to not properly divide and die? Well the cells center, the nucleus, is responsible for commanding the cells functions, but it doesn’t always send the right orders. So the question know becomes, why doesn’t the nucleus send the right commands?
Throughout life, many individuals experience difficulties due to growing up in everyday life. While going in depth of the human life, it is discovered that there are many diseases and disorders that affect humans’ everyday functions. A very popular disease that has traumatically affected the human body is cancer. Cancer is a disease that spreads throughout your body in many ways. The purpose of cancer is to attach to a blood cell in your body and cause a plague within itself, causing the body to initially shut down and die. This disease contains many forms and have many causes to it. However its main goal is to destroy the human body.
b. Our cells are programed to know when to grow, divide, and when to die, with that said just like any other machine, if these “parts” within our DNA do not work then that is when our machine goes off track and starts breaking down.
Cancer is described as the abnormal growth of cells. Normal cells are replaced with abnormal cells in which their deoxyribonucleic acid (DNA) has been damaged or augmented (McCance & Huether, 2014). Cancer cells with their various DNA changes are characterized by growing uncontrollably, being immortal with an unlimited lifespan
When cells in the body start dividing and regenerating uncontrollably, they lead to cancer – and this is true for all the cells in the body. If the cancer is not nipped in its bud early on, it can spread to other parts of the body. This presents the common question asked regards cancer; how can it be stopped early on? The same can be said for cancers that start from the bone marrow such as multiple myelomas.
Human life starts from a fertilized cell which breaks down, again and again, an adult human body is composed of the abundance of cells and each one have their own specific function to perform. During adulthood, most of the cell does not duplicate except some cells continue to divide to replace the old or damaged cell in blood, skin and intestine. This growth is very controlled and no excessive cell growth takes place. But sometimes when a mutation occurs in one or more genes which causes unnecessary cell reproduction and as a conclusion, there is no control over the growth of cells. It is called malignant transformation and this is the starting of cancer (Hosick et al., 2015). There are many different types of cancer but the early stage diagnosis
Besides fetal stem cells, adult stem cells are also researched for new therapies yet are not as effective. According to the National Institutes of Health (2015), the stem cells obtained from an embryo are analyzed in order “to identify how undifferentiated stem cells become the differentiated cells that form the tissues and organs.” Many diseases are caused by an abnormality of cell division and cause the body to decline in health over time. The most common disease of abnormal cell growth is cancer, which destroy body tissues. Although there are
This measure is effective in destroying harmful mutations before divisions can cause the mutation to spread and harm vital organs. Furthermore, while normal cells have a finite life span, such that after approximately 50 to 60 divisions they become senescent, cancer cells continue growing indefinitely, and are thus called immortal.
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).
There are many type of cancer, once the abnormal cells grow out of control all cancers are starting. Cancers can cause serious illness and death if it is untreated. Trillions of living cells are made up in the body. Normal cells have the ability to grow, divide to produce new cells, and then die in a systematic way. During the early years of life, the normal cells confer the person to grow by dividing faster then the cells divide only to change worn-out or dying cells or to reform injuries when the person becomes adult.
The body is made up of trillions of living cells; producing new ones constantly while others die. Normal body cells grow, reproduce, and die in an orderly way. During the early years of a person’s life, normal cells divide faster to allow the person to
Cancer is without a doubt a scary and deadly disease to have, but is it solely responsible for killing the patient? The term cancer is a term used for a several related diseases. All cancer has the similar abnormality where cells grow at an uncontrollable and exponential rate. In a healthy person “cells grow and divide to form new cells as the body needs them” (Institute). As the cells age they naturally become damage and degrade, these damaged cells die, and new cell are produced to replace them. This is the natural process of the cell. In the case of cancer cells, these natural functions mutate and become abnormal. Instead of old damaged cells
Researchers discovered another factor that would put people at risk of getting cancer. Poor lifestyle choices and inherited genes are known to increase a person’s risk of developing cancer, but research concludes that stem cells division are a major contributors to cancer overall. Stem cells are one of the human body's master cells because they are able to maintain the ability to divide throughout life, give rise to cells that can become highly specialized, take the place of cells that die or lost and renew and repair any body tissue. However, there is a risk that genetic mutations will randomly appear as our stem cells divide. The cancer risk varies in the tissue since they are the only cell type with the ability to carry a tumor. Habibul
One in five deaths today is a result of some form of cancer. This terrible disease stems from mutations in body cells, which interfere with the cells’ normal regulation of growth, division, and death. Cells can make occasional mistakes and divide too early or not destroy themselves at the right time (Alberts et al. 2014). The Hayflick limit, described in 1961 by Leonard Hayflick, states that normal human cells can divide for about 50 times (Watts 2011). In cancers, though, this limit does not exist, and cells continually divide. Occasional mistakes do not have tremendous consequences on large, multicellular organisms, however. When many cells begin to make these mistakes, though, tumorigenesis and cancer can occur.
At this stage patients can control the disease by protecting the remaining cells from further damage.7
