Cancer affects everyone. Most people in the world know someone who had cancer, has cancer, or passed away because of cancer. Cancer is an abnormal growth of cells that divide quickly and spread throughout the body. It is a group of over 100 different diseases that can appear anywhere on the body. With the disease cancer arising to become the biggest disease known to mankind, scientists have come up with many notes about cancer such as the origin, forms, like lung cancer, the stages, and ways to prevent or treat lung cancer.
Cancer has been around for millenniums. Cancer has been discovered in ancient manuscripts, fossilized bones, and mummies in Egypt. Without the word being used, cancer has been described to have been around in 3000 B.C. It is described in the Edwin Smith Papyrus, an old Egyptian book on trauma surgery. “The writing says about the disease, ‘There is no treatment’”(“Early History of Cancer.”). Later, during the century before the switch over to the “Anno Domini” time, a roman physician translated the Greek form of “carcinos” and “carcinoma” to cancer, which means crab, in latin ("Early History of Cancer.").
There are two things a normal cell can do when damaged, repair itself or die. Cancer cells on the other hand decide to do neither. They continue to grow and form new, non-normal cells. These cancer cells can invade other parts of the body than just the area in which they choose to be different. This is what makes a cancer cell a cancer cell. As explained before, when a cell is damaged, specifically the DNA, the cell chooses to neither repair itself nor die. It continues to live and forms new cells the body has no need for, and it also contains this broken DNA. Cancer spreading around the body can vary in time...

...all together. Throughout all the fatalities of the wars America was involved in, smoking has killed 10 times more than that amount of people. Within the last 50 years smoking has been an increasing risk in people in the U.S. Smoking increases the likelihood to have both heart diseases and strokes. Although lung cancer is the main result of smoking, cigarette smoke can cause cancer is most places within your body. Cigarettes can destroy the human body. The CDC also states that smoking can affect bone health, teeth, gums, and most organs in the body. Another danger of cigarette smoking is for pregnant woman. Smoking can increase the chance for an early pregnancy, stillbirth, low weight, and SIDS or sudden infant death syndrome. It is certainly horrible to harm your own body, but when it comes to a life of another no person should take that chance ("Cigarette Smoking.").
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).
In general, the word cancer is the name given to a collection of related diseases (What is cancer? n.d.. ). In our everyday life multiple thousands of your cells divide in order to keep the function of that certain cell ongoing. Through out all types of cancer, the body begins to force cells to divide without cease which then spreads to the surrounding tissue. Cancer can take form in any part of the human body, were thousands of cells are cancerous. Through time human cells grow and divide to form new ones as it is a requirement for the body to keep functioning. Therefore
To understand more about this disease I did a research on it, and according to the National Cancer Institute: “Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph system”. Also, there are more than 100 different types of cancer. Cancer is not a single disease, but a group of related diseases.
According to “Medical News Today” cancer is a disease that is caused by an over growth of anomalous cells on one or more lungs. Cells often go up the air pipes which can cause difficulty to breath. Due to the over production of cells the tissue cells often begin to over produce; which results in tumors. There are two types of tumors: malignant and benign. Malignant tumors are the more dangerous of the two due to its invasive nature; which makes it cancerous. While benign is not invasive in other words non-cancerous. This is why cancer spreads to multiple areas and can be sometimes very difficult to fight. Cancer cells are abnormal not only because of their evasive nature, but also because of its irregular life cycle. Rather than expire like a regular cell, they continuously grow and duplicate which causes the disease to spread. This makes cell abnormal in shape and other qualities; known as a sickle cell. Due to the large growth and reproduction rate of the cells this makes the spreading of the cancer more rapid. Each cancer has specific symptom, for lung cancer the sympto...
...of not only them but also other things. (Schulz 2005). Finally, in conclusion, gene mutations and alterations affect the body’s ability to control the rate of cell division, which therefore defines cancer the direct result of gene mutation. Cells affected by mutations are exposed to the reproduction into a tumour. Once the tumour expands in growth, more and more mutations occur in subsequent cell divisions and eventually become a dysplasia and instigates invasion into surrounding tissues. In simpler terms, the cancer is spread to other organs and parts of the body. Following this, metastasis occurs resulting in the cancer spreading through the person and/or animals blood stream and/or lymphatic systems and forms other colonies which thus secretes other harmful organelles, and also disrupts normal bodily function, and possibly leading to and eventuating in death.
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 is a deadly disease that affects millions of American families each year. In cancer, cell division isn't controlled. Usually, cells have to go through a set of checks and balances before they divide, in cancer that is nonexistent. The cells just keep duplicating until they eventually form disorganized clumps called tumors. Tumors can either be, benign, meaning that they do not possess the power to metastasize to surrounding areas. If a tumor has the power to metastasize, it is classified as a malignant tumor. In simple terms, a benign tumor is not cancerous, and a malignant tumor is. Cancer cells cannot perform the necessary functions they were created for. Some types of cancers, like pancreatic cancer, cannot be cured. Other cancers such as melanoma and breast cancer have high survival rates when caught early. The four major types of treatments used to treat cancer include, surgery to remove the affected organ, radiation, chemotherapy, or biological treatments.
Cancer is the name given to a collection of related diseases. In all forms of cancer: the cells in the body begin to divide uncontrollably and then spread into the surrounding tissues.
Cancer can affect anywhere from the brain, lungs, and liver, to the breasts and heart. One of the most common types of cancer is “Carcinoma” “Cancer that begins in the skin or in tissues that line or cover internal organs -- "skin, lung, colon, pancreatic, ovarian cancers," (Medicine net)”. This shows that dozens of different types of cancer only fall into a small category and can all only be treated by certain means. Some types of cancers are even incurable making them particularly dangerous because once you get one of those types of cancers there is nothing that you can do except wait for the inevitable death that awaits you. Meanwhile other forms of cancers are minor, meaning that there is therapy and cures for them, however just because they are minor compared to the more deadly types of cancer, all forms of cancer are extremely potent and dangerous. Sarcoma is another form of cancer “that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue -- bone, soft tissue cancers, (Medicine Net)”. This form of cancer affects the body by taking out the supportive tissues and functions, causing extreme pain and discomfort for whom ever is unlucky enough to get it. One of the most common types of cancer is leukemia which “Cancer that starts in blood-forming tissue such as the bone marrow and
“Since 1990, over 6 million Americans have died of cancer, more than the combined casualties from the Civil war, WWII, and the Vietnam and Korean conflicts combined” (Faguet, p. 5). According to American Cancer Society projections, there were 1,529,560 new cases of cancer in 2010. Cancer is becoming more and more common around the world. New cancers are constantly being discovered. Researchers are finding new ways to detect cancer and treat it so that the fatality rate does not rise. However, there are some cancers that researchers have not yet discovered a cure for. It is very important for Cancer Research to continue so that one day these cancers will no longer be a treat.
According to the Partnership for a Drug-Free America, it stated that the nicotine in smoking cigarettes can be very dangerous, damaging to the human body. It’s known that smoking can cause chronic lung disease, coronary heart disease and stroke. In addition, smoking also causes cancer of the lungs, larynx, esophagus, mouth, and bladder. Smoking tobacco products is also known to contribute to cancer of cervix, pancreas and kidneys. People that don’t smoke tobacco products can also be harmed by second hand smoke. Women who smoke while pregnant, put their baby at risk of have health problems.
Researchers over centuries have been examining various cellular aspect of cancer as well as the knowledge of what separates a normal cell from a cancerous cell. The advancement of technology plays a large role in the research development of cancer. It is evident that there are different factors that contribute to the rapid growth of cancer cells. Thu, justifying the complex nature of cancer and the need for continual research needed to be able to have a complete understanding of the disease cancer.
Cancer is a type of disease that has many variations. it is an extremely broad disease, consisting of over 200 different types. It affects millions of people around the world each year. The disease occurs because of an irregular cell growth in the body. The cells uncontrollably divide and grow through the process of mitosis. This creates either benign, or malignant tumors. Benign tumors are not dangerous, but malignant tumors are dangerous and are given the term ‘cancerous’. The malignant tumors can invade other parts of the body by traveling through either the bloodstream, or the lymphatic system. It is a very dangerous disease, it is not contagious, and it can be cured if it is diagnosed and treated early. Many cancers have a different mortality rate, but not all of the different types of cancers have a high mortality rate.
Did you know that in 2011 there were more than 6 million tobacco caused deaths worldwide (Henningfield)? Smoking is the act of inhaling and exhaling the fumes of burning plant material. Because there is nicotine in cigarettes, they are highly addictive. Cigarettes are one of the worlds most devastating causes of death and disease (Henningfield). There are many negative effects from secondhand smoking, both immediately and over time. Smoking also affects the environment indoors negatively. Also, when pregnant woman or parents of young children smoke, they could harm their children. People should not smoke with others around because they are exposed to harmful chemicals and they are not the one putting themselves in danger.
Cancer is a disease that affects human somatic cells. It causes the cells to divide uncontrollably and form masses known as tumors. There are two different types of cancer tumors. Some tumors are benign and other tumors are malignant. Benign tumors look similar to the tissues that they came from and develop slowly. The tumor remains in the same area that the tumor originated in. Malignant tumors are formed from cells that do not resemble the tissue that they came from. They vary in shape and size. This enables pieces of the tumor to break off and spread to other places in the body. Over the past few decades cancer has become a very prominent disease. There are many different types of cancer and many different causes for the the disease. Most cancers are because of a genetic mutation. The most common type occur when a cell is dividing. Proto-oncogenes, which are alleles in a normal cells, mutate to form oncogenes. These oncogenes cause cancer because they do not allow the cells to self destruct or become epistatic. There have been several research projects which have been testing epistatis.
