Cancer Essay - 614 Words

Cancer Cancer is a disease in which cells grow out of control and invade, erode, and destroy normal tissue. Damaged genes cause this development of cancer. These damaged genes are often a factor caused by such things such as the environment, and can be influenced by inherited factors. As the very early damaged cells divide they can evolve into a malignant cell population, and lose the control mechanism that govern normal cell division. These malignant cells can then go on to form solid tumours that start to destroy normal tissue. These can then spread to other parts of the body by releasing these tumour cells. Once these cancer cells spread, they grow in other parts of the body and then form†¦show more content†¦These are known as mutagens. These carcinogens can cause errors, duplication or rearrangement in DNA sequences that contribute to the progression of cancer. An example of a carcinogen is tobacco. Tobacco smoke contains at least twenty carcinogens, which are known to caus e lung cancer. Age can be a factor when asked what causes cancer. This is because cancer becomes more common as we get older. 85% of cancers are diagnosed in patients over fifty-five. This is because as we get older we become more susceptible to some types of carcinogens. Age is also a cause as it takes a long time for a cell to become cancerous, as there has to be a number of changes to the genes within a cell, before it turns into a cancerous cell. Therefore the longer we live; the more time there is for us to become susceptible to these mistakes in our genes. Our genetics are also another cause of cancer. If we are born with one of these genetic mutations, which can cause cancer, we are said to be genetically predipositional. This is known as many of the genes that control cell growth, and DNA repair are associated with inherited cancer susceptibility. The genes, which are susceptible to leading to cancerous mutations, are called proto-oncogenes. They are called oncogens as the word onco means cancer. An example of this is the faulty genes, BRCA1 and BRCA2. If a woman carries one of these genes, she isShow MoreRelatedCancer : Cancer And Cancer1673 Words   |  7 PagesCancer Cancer is one of the leading causes of morbidity and mortality worldwide, with approximately 14 million new cases in 2012.2 The amount of new cases is expected to rise by about 70% over the next 2 decades. Cancer which causes nearly 1 in 6 deaths, is the second leading cause of death globally, and was responsible for 8.8 million deaths in 2015. Approximately 70% of deaths from cancer occur in low- and middle-income countries. In 2012 about 14.1 million new cases of cancer occurred globallyRead MoreOvarian Cancer : Cancer And Cancer988 Words   |  4 Pages Ovarian cancer is a disease in which malignant or cancerous cells are found in the ovaries. The ovaries are two small organs that are located on each side of the uterus. The way cancer develops is when cells begin to grow out of control. Cancer cells are different from normal cells because they continue to grow and instead of dying, they create abnormal cells that form into a tumor. Woman around age 35-74, ovarian cancer is the fifth leading cause of death. The earlier this cancer is treated theRead MoreCancer : Cancer And Cancer1998 Words   |  8 PagesAbstract In women, one of the most common cancers of course is breast cancer, in men prostate cancer and in men and women, lung cancer and colon cancer are common cancers. It is important to understand that the cancer that occurs in one individual is very different from the cancer that occurs in another. Everyone is different; a lung tumor in one person will be different from a lung tumor in another person. Once a diagnosis of cancer is made, the next obvious question is what do you do? ThereRead MoreBreast Cancer : Cancer And Cancer1341 Words   |  6 PagesWhat I chose to research on my cancer project was breast cancer, since breast cancer is one of the second deadliest cancers among women I felt like I should research into this topic more in-depth. Anyone, no matter male or female, we are born with some breast cells and tissue. Even though males do not develop milk-producing breasts, a man s breast cells and tissue can still develop cancer. Male breast cancer is very rare, yet more fa tale because they are less likely to assume the lump is possiblyRead MoreOvarian Cancer : Cancer And Cancer1577 Words   |  7 PagesOvarian cancer is also one of the cancer that is affecting millions of women in today’s world. The previous researches were claiming that ovarian cancer comes from ovary cells. However, studies have found that ovarian cancer could be coming from fallopian tube. Dr. Burdette’s lab researched how fallopian tube can be contributing to ovarian cancer, and her research shows strong evidence of how does it occurs. It is very important to find a cure for ovarian cancer, otherwise deaths due to ovarian cancerRead MoreBreast Cancer : Cancer And Cancer1115 Words   |  5 Pagesaround the world develops the most common disease called Breast Cancer. In the United States, about 200,000 women suffer from this disease and it causes more than 40,000 death each year. Breast cancer is a cancer cell (malignant tumor) that forms in the breast. The cancerou s cells grow in the breast and then invade the healthy cells and the surrounding tissues of the breast and it can also spread into other parts of the body. Breast cancer is more common in women but men can also get it too. One of theRead MoreBreast Cancer : Cancer And Cancer896 Words   |  4 PagesBefore going in depth, let us first define what breast cancer is. According to the National Breast Cancer.Org â€Å"Cancer is a broad term for a class of diseases characterized by abnormal cells that grow and invade healthy cells in the body. Breast cancer starts in the cells of the breast as a group of cancer cells that can then invade surrounding tissues or spread (metastasize) to other areas of the body.† Cancer begins in the cells which are the basic building blocks that make up tissue.

The build up of those cells can go on undetected for quite some time before pain or any symptoms show themselves. Also some of the pains can be mistaken for symptoms of some other less severe conditions. The pancreas is the organ that produces digestive juices and hormones that regulate blood sugar. Cells called exocrine pa ncreas cells produce the digestive juices, while cells called endocrine pancreasRead MoreThe Disease Of Cancer And Cancer975 Words   |  4 PagesCancer is the name given to a collection of many diseases. Cancer is uncontrolled cell division due to genetic changes that interfere the cell cycle and activate cell division. The cancer start in any part of the human body, such as in blood, lung, and colon. Cancers are different in the ways they spread and grow. Cancers types have its own characteristics. The general characteristics of Cancers are they work in the absence of growth factors, make their own growth factors, don’t respond to the signal
