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…
Lung cancer is the uncontrolled growth of abnormal cells that start off in one or both lungs. It usually happens in the cells that line the air passages in your lungs. These cells that form in the lungs do not develop into healthy lung tissue, but it divides rapidly and forms tumors. When these tumors grow they make it such a problem that it slowly stops the lungs ability to provide the bloodstream with oxygen. The tumors that remain stable in one spot and do not spread throughout the lungs are called benign tumors. Preventing cancer is such a necessity and an essential component to cancer control plans because an estimated number about 40% of all cancer deaths could have or can be prevented.…
Anal malignancy and colorectal disease are two distinctive sorts of cancer. The colorectal tumor influences the colon and the whole rectum, while anal tumor…
1. Cancer is the disease caused by an uncontrolled division of abnormal cells in a part of the body. Biopsy is an examination of tissue removed from a living body to discover the presence, cause, or extent of a disease. Tumor is swelling of a part of the body, generally without inflammation, caused by an abnormal growth of tissue, whether benign or malignant. Malignant Melanoma is a type of cancer arising from the melanocyte cells of the skin. Melanocytes are cells in the skin that produce a pigment called melanin. Malignant melanoma develops when the melanocytes no longer respond to normal control mechanisms of cellular growth. They may then invade nearby structures or spread to other organs in the body (metastasis), where again they invade…
When people hear the word cancer, they think of a terrifying, life threatening disease. Have they ever thought of how it even started? Cancer cells grow and spread throughout the body in many ways, and sure you can catch it early but not usually. Cancer spreads to many things in and on the body, not just where the cancer is, but especially all of the bloodstreams in your body.…
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.…
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…
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 the name for a group of 100 diseases in which abnormal cells in a part of the body begin to grow out of control. Lung cancer occurs when this uncontrolled cell growth begins in one or both lungs – American Cancer Society…
The stages of pancreatic cancer are used to describe how advanced the cancer is in your body. The higher the stage number, the more widespread the cancer is. These stages are important when choosing the best treatments for you.…
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).…
A disease is ‘an abnormal condition affecting the body of an organism.’ Diseases can be long term and can even cause death. Individuals may have a disease but not show any symptoms, not feel ill and even have a disease without them realising. Examples of diseases can be cancer, cholera, tuberculosis etc. Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer can spread to other parts of the body through the blood and lymph systems; this shuts down the body. There are more than 100 different types of cancers. The different types of cancer are named from which organ the start in. For example cancer that begins in the colon is called colon cancer.…
There are roughly around 200 types of cancer. They are usually named after where they start. Some cancers are bone cancer, lung cancer, blood cancer, and skin cancer. Bone cancer, which is also called sarcoma often starts in the leg and arm. Terry fox had bone cancer in his right leg. Lung cancer starts in the lungs. It is also called mesothelioma and is mostly caused because of smoking. Even if you don’t smoke, but live in an area where many people smoke you can get lung cancer. Blood cancer which is also called leukemia starts in the tissue that forms blood. Skin cancer is cancer that is formed on your skin. Excessive use of sunlight on your body can cause skin cancer. Skin cancer can be removed by getting surgery. Some of the effects of cancer are death, anger, sadness, depression, stress, fear, and anxiety. Cancer can be caused by many things. A common cause is smoking. Smoking is very harmful to your body. Even if you don’t smoke and you’re with someone who is smoking can get you cancer. Eating fat foods can also get you cancer. You should eat a lot of vegetables and fruit.…
Cancer is a disease caused by normal cells changing, so that they grow in abnormal and uncontrolled way. The uncontrolled growth of cells form a lump called tumour. Once the tumour has become cancerous it can cause problems in the following ways:…
There are many different kinds of cancers. Cancer can develop in almost any organ or tissue, such as the lung, colon, breast, skin, bones, or nerve tissue. It is caused by the uncontrolled growth of abnormal cells in the body. Our daily lifestyle is one of the risk factors why malignant cells grow. Drinking excess alcohol, excessive sunlight exposure and obesity are some of the bad habits we practice.…
