About Cancer
Based from worldwide statistics, cancer is the leading cause of most diseases. The estimated number of new cases of cancer is around 14.1 million. Out of that number, the most common cases that occur around the world are lung cancer, female breast cancer, bowel/colorectal, prostate cancer, stomach cancer and liver. If one considers the nature of cancer, most likely the numbers will keep on growing.
Cancer has always baffled researchers due to the nature of the disease. As most of you would probably by now, cancer is a type of disease that involves abnormal cell growth. Cancer is different from most diseases because it’s not directly caused by pathogens. Furthermore, what causes the abnormality of the cell can’t be pinpointed

Each cell contains genes, which is constituted by our DNA. Since DNA is responsible for most of the genetic instructions used in the development, functioning and reproduction of every living organism, it also plays a role on the function of a cell. A cell becomes cancerous if something may have altered the genetic information of that DNA. In time, the cell becomes malignant and performs beyond its normal homeostatic function. It will self-replicate until it spreads throughout your body. If the cancer isn’t treated, it will result to death.
Cancer Risk Factors
While it is impossible to identify the early development of tumors, researchers have managed to list particular cancer risk factors. These factors are usually based on monitoring groups of people and compare those who develop cancer with those who don’t. Through these surveys, researchers would usually track down trends, habits, and other noticeable factors that are common amongst people who acquire cancer.
Age
As you grow older, the more you are prone to having cancer. However, it’s not always true. There are certain types of cancer that develop during childhood. For example, some children and young adolescents have been known to be prone to
Cancer has been an active concern in our society for the past couple decades, since we truly discovered the nature of cancer and the potency it brings along with it. However, it was not until the mid-20th century that scientists were beginning to truly understand the origin of cancer. Scientists dating back all the way to the Renaissance, when they first began performing autopsies to learn more about the human body and form, noticed abnormalities but it never clicked that it was something much worse than it seemed. Research has continued since then, and it has continued to thrive even to this day. When James Watson and Francis Crick discovered DNA and it’s chemical structure in 1962, it opened up doors that even they could not expect. With the understanding of DNA and how it affected the way we look at life, came the beginning of the understanding of mutated DNA (which is a cause of the growth of cancerous cells). In this past century, researching scientists discovered that cancer is linked with the DNA that resides in a cell’s nucleus. By ways of damage to the cells via chemicals or radiation, or even introduction of a new DNA, the cancerous cells begin to form and duplicate. We are learning more and more about cancer and how to fight it, but we still have much more to learn.
Cancer is the term used to describe a group of diseases consisting of hundreds of ailments and although there exists so many different types of cancer, they all begin in a similar way. The body is made up of over a trillion cells, and cancer is the uncontrolled growth of malfunctioning cells in the body (Dawson, 1996). “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” (American Cancer Society, 2012).
The world we live in can be wonderful at times,but can also be dangerous and danger isn’t a good place to start at.The word cancer seems terrifying when someone thinks about it and they should be because there is a lot of types of cancer from all over the word.Cancer is the leading causes of death everywhere you go and it happens from different parts of the body.From someone that doesn’t understand cancer it’s very important to know about the aspects in which they come around.They way a cancer forms,symptons that are caused,and the way each cancer type is treated is very important to consider.
Breast Cancer is a disease that can sometime lead to ovarian cancer and has caused a lot of women’s death. “About five to ten percent of breast cancer cases are thought to be hereditary, meaning that they result from gene defects called mutations inherited from a parent”. Related Risks early menstruation, oral contraceptives and child bearing 20 percent. (1)An environmental risk is that toxins can damage breast DNA. Over time damaged DNA can lead to cancer. Your risk of developing breast cancer increases as you get older. “1 of 8 breast cancer are found when women are younger than 45. 2 of 3 breast cancer are found in women age 55 years or older 75 percent greater chance”.(1) Breast Cancer can lead Peutz Jeghers syndrome the effects of Peutz Jeghgers is spots on your lips and in their mouths. Women with no children or who had a child after age 30 have slightly higher breast cancer risk. “Screening for breast cancer is early diagnosis increases chance of survival and annual mammogram after age 40”. Women who took Diethylstilbestrol while pregnant could have a slightly higher risk of developing breast cancer. Birth control peals also cause higher risks 40 to 50 percent for breast cancer risk calms down after they have stopped taking them.(1) Using combined hormone therapy after menopause increase the risk of getting breast cancer , it also increase women chances of dying from it. If you are over weight or obese after menopause greatly increase breast cancer risk 20 percent. Drinking alcohol can cause a major effect for you to start developing breast cancer the risk increase the more you drink. Tobacco smoke, Night work, Antiperspirants, Bras and Induced abortion. Breast cancer takes a lot of toll on women and men of all races and...
One half of men and one third of women will get cancer in their lifetime. ½ million people are going to die this year, that’s more than 1,500 people per day! One in eight deaths in the world is due to cancer. Cancer causes more deaths than AIDS, tuberculosis, and malaria combined. Cancer is a disease that’s preventable, curable, and deadly.
To begin, cancer starts to form when abnormal cells grow. Abnormal cells form when the DNA, is damaged. The fewer the amount of abnormal cells, the more treatable the cancer will be. In normal cells, the damaged DNA either gets repaired, or dies. In cancer cells, the damaged DNA doesn’t get repaired or dies like normal cells. The damaged cell instead replicates itself. It is difficult to understand exactly why or how cancer starts to grow, but common reasons can be from sun exposure or cigarette smoking. Cancer cells usually form a tumor. A type of cancer where a tumor doesn’t form is Leukemia. On the other hand, not all tumors are cancerous. There are benign and malignant tumors or masses. Benign tumors cannot spread to other organs of the body, but can be on the larger side and press on other organs. Benign tumors are not cancerous, but can still instill problems. Benign tumors can become malignant, or cancerous, after a period of time. Malignant tumors are the ones that are cancerous from the very beginning. This ...
Cancer has become the one of the most feared things for human beings. The various type of cancer have been discovered and there are still a lot of it that undiscoverable. Cancer is a complex disease that have a group of disease. The cancer itself cannot be describe by words. The causes of this cancer is still not being able to be discovered fully. There are only minor factor that can lead to this disease. The carcinogens are believed to be one of the causes that lead to cancer such as asbestos, radon gas, tobacco, PVC and much more from our chemical industries. The environment especially near to the industrial that produce chemical waste can be one of the causes lead to cancer. Cancer also have relation with our age, lifestyle, and diet and also can be genetically inherited. It is believed that older people have higher tendency to get cancer than younger people. Our lifestyle and diet also plays a role causing a cancer by our daily life routine. Smoking tobacco and eating unconsciously (still in research) can also increase the possibility to get cancer especially lung cancer that cause by smoking tobacco. There are several cases, cancer were inherited from their parents. Various type of viruses such as HIV, HPV, EBV and many more virus has a high capabilities to increase the chance a patient to get a cancer because these viruses lower their body immunity to disease.
Cancer has become a very common illness worldwide for any age, but mostly affecting adults. One can get cancer from different places in the body, that is why there are so many people with cancer, because of all the different types. Cancer can affect any gender, female or male, and any age. It varies from ovarian cancer to prostate cancer, skin cancer to lukemia. Cancer has been a problem for many years, yet we have not found a cure to treat and prevent cancer.
Cancer directly affects the lives of approximately 13.7 million Americans. In 2014 alone it is estimated that there will be 1,665,540 patients diagnosed with cancer (Jones). Of these people, 43, 250 people will be diagnosed with oral cancer (Douglas). 585,720 Americans are expected to die of cancer in 2014 at a rate of almost 1,600 people per day. Cancer has become the second most common cause of death in the US. It accounts for 1 in every 4 deaths despite having an 80 to 90% survival rate for oral cancer (Jones).
Cancer is a major public health problem in many parts of the world. Over ten million new cases of cancer, with over six million deaths were estimated in the year 2000 (Parkin, 2001). The estimated numbers of incidence and mortality in 2002 were markedly increased as 10.9 million new cases, 6.7 million deaths with cancer (Parkin et al., 2005). Even developed countries suffering from cancer, in USA it was expected 2677860 new cases of cancer will be diagnosed in 2009. In that same year , more than 562,340 deaths will occur due to cancer, this number represent 25 % of all deaths and makes cancer as a second leading cause of death after heart diseases (Jemal et al.
However most cancers mainly affect older people. Therefore as the average life expectancy in the United Kingdom has almost doubled, the risk of cancer has grown. It is estimated that a third of all cancers are caused by smoking and another third is caused by the diet people choose. These are over two hundred different types of cancer, and all have different causes, different symptoms and require different types of treatment. Some types of cancer are very common, such as breast, lung, bowel, and prostate cancer, whereas some types of blood cancers are very rare.
For years people have tried to figure out one big question. What is the real cause of cancer? After much research, the statistics say that cancer is a disease of the modern world (Stevenson 1). A few main factors that cause cancer are the use of tobacco, industrial agents, and a person’s weight and diet. (Landau 2-4). The modern environment and everyday lifestyle of people contain factors that cause cancer.
Though there are many types of cancers, there are four main cancers that effect today’s society. These cancers include prostate cancer, breast cancer, lung cancer and colon/rectum cancer. Of the 1,529,560 new cases of cancer in 2010, 217,730 were prostate cancer, 209,060 were female breast cancer, 222,520 were lung cancer, and 142,570 were colon/rectum cancer. The majority of people who have cancer will have one of these types of cancer.
Cells are classified as cancerous after a series of mutations that cause them to be abnormal. ...
Family members with breast cancer - A family history of breast cancer may increase your risk of breast cancer. But just because someone in your family has breast cancer does not mean you will have it too. About 75% of patients with breast cancer do not have a family history of breast cancer Early menstruation, late menopause - Menstruation before the age of 12 and menopause after the age of 50 can increase your risk of cancer. Age - Women who are older have a higher risk than women who are younger.
