The Leading Cause Of Cancer

Cancer is ultimately the result of cells that uncontrollably grow and do not die. Normal cells in the body follow an orderly path of growth, division, and death. Programmed cell death is called apoptosis, and when this process breaks down, cancer begins to form a tumor.

Cancer starts with the normal cells in our bodies. Normal cells divide in processes called Mitosis and Meiosis which is how our bodies grow, heal and repair and when cells become old or are damaged, they die and new cells are created. However, when this cell division process goes wrong the cells become abnormal. Cell abnormalities occur when the cell makes errors whilst copying the genes. As the cell becomes more abnormal, the old and damaged cells do not die when they are supposed to but the new cells, that are supposed to go in place of the dead cells, are still produced. The extra cells divide uncontrollably which is how a tumour is formed.

There are a wide variety of cancer types. They all have several things in common, however. Each cancer starts with cells that become abnormal or cancerous. These cells reproduce and form a mass of cancerous cells. This mass is called a tumor. When the cancerous cells spread, or metastasize, they can impact other tissues, organs, and systems of the body. A second commonality among cancers is that when they are detected early, they are easier to treat and the treatments are more likely to work. In many cases, a cancer that is caught early can be completely destroyed.

There are many types of cancer but they all start the same way. Breast cancer is mostly common among women. The body is made up of millions of cells. When one cell dies the body creates a new cell to replace it. These cells will normally grow, multiply,and die according to a schedule that keeps your body functioning. Inside

When someone says the word “disease” or “illness” the most common association with these words are Cancer. Cancer is so frighteningly common that it is expected by The American Cancer Society to have 564,800 people die of cancer this year which is a little more than 1,500 people a day. Cancer is the second leading cause of death. With these statistics to back up Cancer one will see walks supporting cancer, media discussing possible new found cures, nfl football players wearing pink to support breast cancer awareness, the Susan G. Komen foundation and so many other big foundations raising millions of dollars towards a cure. Where are the walks or large foundations to raise awareness of diseases for psychosis such as Schizophrenia? Schizophrenia

Cancer is one of the most lethal diseases that greatly contributes to the death toll of millions people around the globe. Cancer is a class of diseases characterized by out of control cell growth. There are over 100 different types of cancer, and the type of cell that is initially affected classifies each. In most cases, cancer harms the body when damaged cells divide uncontrollably to form lumps or masses of tissue called tumors. Untreated cancers can cause serious illness and death.

Cancer harms the body when altered cells divide uncontrollably to form lumps or masses of tissue which is called tumors (except in the case of leukemia where cancer prohibits normal blood function by abnormal cell division in the blood stream). Tumors can grow and

Cancer is the most prevalent public health challenge worldwide, hence becoming the second leading cause of death in 2013 (cite!). The illness develops when abnormal body cells survive and new cells grow, which are to replace old and damaged ones (cite!). Healthcare professionals associate cancer prevalence with risk factors such as smoking and obesity (cite pg#87) and according to research studies, one in every three individuals will develop cancer (cite!). Such statistics correspond to the occurrence of cancer in the United States, with prostate cancer affecting 105.3 per 100,000 people nationwide (cite!). For the past decade, cancer drugs have increased from $10,000 in the 1990s to $100,000 by 2012; therefore, many patients may die because

By definition, a cancer is a disease that is characterized by “controlled growth and spread of abnormal cells,” (Laini, online). According to Laino, cancer forms when there is a growth of abnormal cells. The abnormal cells also known as the cancer cells grow and forms a tumor in which will began to attack nearby body tissues and organs. Depending upon the various types of cancer, the cancer cells attacks different tissues and organs. As the tumor spreads, some

Cancer is a disease caused by an uncontrolled division of abnormal cells. In a cancerous cell cycle, the cell ignores the signals that tell them to stop, and it just keeps dividing. Normal cells stop dividing when your body do not need anything else, but cancer cells just continue to go through cell cycle to make more copies. Also, cancer cells do not need anything to stimulated their growth, and it can spread to other parts of the body. The most common causes of cancer are tobacco, alcohol, overweight, obesity, dietary factors, physical inactivity, chronic infections, radiation, sun and UV exposure. The most common types of cancer are lung (158,080 deaths per year), liver (27,170 deaths per year), stomach (10,730 deaths per year),colorectal

“Cancer”, its a disease that have claimed the lives of millions, its a disease that has not been cured, and its a disease that have many different forms. There are many types of cancer. It can develop in almost any organ or tissue, such as colon, lung, skin, bones, breast or nerve tissue. Cancer is defined as “a malignant growth or tumor resulting from the division of abnormal cells.” Some of the body cells begin to divide without stopping and spreading into surrounding issues. As cells become abnormal, old and damaged cells survive somehow when they should die, and the new cells form when they are not needed. Cancers of the blood, such as leukemias generally do not form solid tumors. These cells can divide without stopping and may form growths called tumors.

In our body we have trillions of cells that have different functions. All parts of the body, organs, muscles, skin, and even bones and blood are composed of these cells. Cells are constantly growing and multiplying to replace old damaged cells. Cancer starts in our cells that are tiny building blocks that make up the organs and tissues of our body. Each cell has a controlled center called a nucleus. The nucleus receives signals from the body to say when the cells should divide and grow and when they should stop. These molecules can work inside the cells or on their surface. The nucleus then tells the cell what to do. Usually cells divide in a controlled way to make new cells, they eventually die and then the body sends a signal to the cell to repeat the process. When cancer is present, the cells do not get these signals from the body, therefore the cells keep dividing and make more and more abnormal cells. These cells form excess tissue or lump called a tumor. These tumors invade and destroy surrounding tissues and nearby organs. Eventually cancer cells break off and spread through the blood to form new tumors in other parts of the body. This process is called Metastasis and it can be a slow process occurring over a number of years, or can happen rapidly within a few weeks. Cancer harms a person in two ways by physically blocking or pressing organs, and by reproducing instead of normal healthy cells. The cancer can cause pain and illness by pressing against nerves or blocking nearby

Human body is made up of trillions and trillions of cells and cancer cells can grow in any part of the body. In natural human body process all the cells keep breaking and new cells keep taking their places and that’s how the body work properly but when cancer cells grows the old cells keep becoming abnormal and the natural process disturbs.

Cancer cells are cells that disregard some needs and limitations of the body. Cells like this are also called malignant cells. However, they can also reproduce. This is when the problem comes in. Daughter cells that are produced by the previous generation of cancer cells are also cancer cells. As time passes, these cancer cells will gather together in clumps and spread into the other parts of the body. These clumps are called metastases. If the cancer cells are not exterminated quickly enough, they can continue to increase in numbers and eventually destroy the part of the body where they are located.

The body is affected on a cellular level by cancer. Going more into detail, cancer is caused by an error in the replication process of a cell. The cell is changed to rapidly and relentlessly reproduce more replicas of its’ mutated self. These cancer cells, along with the power to multiply quickly, have the innate ability to ignore commands from the body about destruction. If there are ever too many cells in the body, messages are sent to perform apoptosis. Apoptosis is where the cell commits suicide, but cancer cells can become immune to this signal. Together the two combine to make an unstoppable cell growing factory.
