Cancer Cells Vs Healthy Cells
The characteristics of a healthy cell and a cancer cell is very different. Healthy cells stop reproducing when there are enough cells, however, cancer cells continue to reproduce. Due to this continued growth a tumor, which is a cluster of cancer cells, is formed. Cancer cells do not interact with other cells like the healthy cells. Healthy cells stop growing when they hear signals from the nearby cells, in contrast, cancer cells do not respond to these signals. When healthy cells get old or damaged they either get repaired or die. On the other hand, cancer cells do not repair or undergo apoptosis. Healthy cells have a special function to perform, however, cancer cells have no specialized function. Cancer cells do not do anything that benefits

    1. Cancer is a group of diseases in which cells grows and divide out of control, it is caused by a change in DNA that controls the cell cycle. This DNA change causes for cells not to stay in interphase for the normal amount of time, and some of the checkpoints fail and cause the cells to divide uncontrollably. The uncontrollable division rate can create a massive group of cells called a tumour. The cells of the tumour may stay together and have no other effect on the tissues around it, this is known as a benign tumour. There is also a tumour known as a malignant tumour, which causes interference with functioning of neighbouring cells and tissues. Malignant tumours could even destroy surrounding tissues, but malignant…

    The Role of Hela Cell in Medical Development

    Long times ago, even during the 19th century, scientist all over the world had started to find the cure for cancer, one of the most feared disease you can ever imagine, simply because you don’t know what the cause and how to turn it off. Cancer started off with something very simple- when they cannot stop dividing. Normally, a healthy cell, when they are matured and ready to divide, will send some kind of information to the neighboring cells that it is going to undergo mitosis- a process of cell division and completed in different stage. In every stage, there will be a checkpoint where the cells are going to be self-examined and in order to pass the checkpoint; they have to be in the completely good condition. The responsible gene to destroy or recycle the damaged cells at the checkpoint is called the tumor suppressor genes. There are many known tumor suppressor genes; the first one discovered by human is Retinoblastoma but the most renowned one is p53. In the damaged cells, however, the tumor suppressor genes are turned off by mutation, which may change, add or delete some of the alleles in the genes, as a result, the gene cannot function in proper manner. In the absence of the tumor suppressor genes, damaged cells can proceed to the next step in mitosis and divide uncontrollably. When the damaged cells divided successfully, the process is repeated in the every daughter cell over and over again and these cells will form a lump of tissue called tumor. The overgrowing of tumor…

    Essay On Carcinogenesis

    The term "cancer" refers to a large group of very different diseases. They have one thing in common: the uncontrolled division of cells of an organ or tissue. These cells do not grow old and die not from spite of many changes in how healthy cells. They disguise themselves so the immune system does not recognize them as ill or injured. It can malignant tumors arise, as in cervical cancer: He is one of the "solid" tumors, as opposed to "systemic" diseases of the blood or bone marrow, in which cancer cells can spread throughout the body from the very beginning.…

    The Process of Cell Multiplication

    Cancer is caused by abnormal behaviour in cells, so it's helpful to understand the difference between a healthy cell and a cancerous cell. Cancer cells are set apart by a few characteristics, including unchecked growth and reproduction. Healthy cells will stop reproducing when they receive signals from nearby cells to do so; cancer cells no longer respond to these signals. Most cells will also cease dividing and reproducing if there's an error in their DNA (known as a mutation). Cancerous cells, by contrast, reproduce despite the damaged DNA and take on powers of immortality instead of dying off. And, finally, while healthy cells will stay put, cancerous cells will move randomly around the body, spreading cancer and making it more difficult to treat. If the reason behind why cancer cells do this would be known, a cure for cancer could be made: the chemical that causes the cancer cells to react could be avoided, and therefore cancer would…

    Esophageal Cancer

    In August 2011, my grandmother died of esophageal cancer. Cancer is the uncontrolled growth of abnormal cells in the body, and cells divide rapidly. Cancer starts as a tumor located in a specific part of the body. A tumor is an abnormal growth of body tissue. There are two types of tumors; benign and malignant. A benign tumor is a tumor that is not cancerous, so it has not yet spread to other parts of the body, but is localized in one area. They grow slowly and until they become a malignant tumor, they are not very harmful. A malignant tumor is one that is cancerous, where the cancer cells start traveling to other parts of the body. Cancer cells invade and damage tissues and organs, and can enter the bloodstream. Proto-oncogenes, a gene in normal cells, both promote and inhibit cell division at the same time. In cancer cells both of these functions are stopped, and cells stop entering G0, the period of the cell cycle where a cell rests and completes basic functions, instead of dividing. Because of this, cells start dividing rapidly. These rapidly dividing cells start off located in a specific location of the body, and as they divide, create a lump, or a tumor. This is known as the benign stage. As the tumor grows, overtime the tumor becomes attached to blood vessels, and travels throughout the rest of the body. Once this happens, the tumor becomes malignant, and is very hard to cure.…

    Cancer is a group of diseases that deal with the uncontrolled growth of cells. A tumor refers to a collection of abnormal cells; some of them are known as benign tumors. Benign tumors do not become a cancer unless they start spreading and growing. Once these tumors begin to grow and multiply they become a cancer. There is screening for cancer available but only colon, breast, cervical and prostate cancer screenings have been known to be effective. Colon cancer or colorectal cancer is the leading cause of deaths in Americans younger than 85 years old. This type of disease develops in the rectum or colon, a person might not know when the tumors grow or begin to spread without screening. For this reason it is recommended that all people over the age of 50 get checked, (Bernard, 2006).…

    Stomach Cancer Research Paper

    Cancer is a dangerous disease that is caused by an uncontrolled group of abnormal cells in the body. Cancerous cells, also known as malignant tumors or neoplasm, begin to divide without stopping and invade surrounding tissues. The body is made up of trillions of cells, which means cancer can start from almost anywhere in the body. Human cells grow and divide to form new cells continuously. When cells grow old or become damaged they die and new cells are formed to take their place. This process is not the same when cancer starts to develop. As cells become more and more abnormal, old, or damaged instead of dying, they survive and these mutated cells no longer exhibit their original behavior. These new cells have the ability to divide without…

    However, cancer cells are also clever enough, and, particularly due to accumulated genetic mutations, they excel in adapting to harsh conditions. The constant immune system assault is highly unfavourable factor for cancer cells. Therefore, cancer cells by various means try to evade the immune system, which seeks to destroy them or weaken their activity. The more malignant and aggressive tumor cells are (this depends on the set of mutations within the cell genome), the more abilities it has to fight the immune system.…
