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.").
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.
..., while a cell undergoes cell cycle, when a cell comes in contact with another cell, it stops reproducing. However, cancer cells continue to duplicate repeatedly until there is a mass of cells or a tumor to form (see figure 9). Lastly, in cell division when there is a mutation or abnormality in the DNA, a normal cell stops dividing. However, a cancerous cell will continue to duplicate and form mutations (“Cell Biology and Cancer”). Also, cancer cells are harmful because they grow and duplicate with complete disregard to the functions and limitations of the body (see figure 10). Also, cancerous cells have the ability to spread through metastasis throughout parts of the body through the bloodstream. In terms of similar behavior to that of normal cells, cancerous cells also duplicate, but at a very different rate ("Cancer Cells vs. Normal Cells: What's Different?").
The creation myth of Cancer is tied to the twelve labors of Hercules. While Hercules battled the Hydra, the goddess Hera saw an opportunity. Hercules was the son of Zeus, Hera’s
Before D.A.R.E., I was not mindful of the extensive damage cigarettes and other tobacco products cause. Cigarette smoke contains over 200 harmful chemicals, including rat poison. Because of nicotine, cigarettes are highly addictive. As a result, smoking is the leading preventable cause of death in the U.S. It causes over 400,000 deaths annually.
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.
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...
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 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.
It has been difficult to develop an accurate definition for cancer. The reputed British oncologist Willis has defined cancer as "an abnormal mass of tissue, the growth of which exceeds and is uncoordinated with that of the normal tissues and persists in the same excessive manner after cessation of the stimuli which evoked the change" (Cotran et al., 1999).
...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.
As most of you know, smoking is bad for your health, but what some of you might not know is that you don’t actually have to smoke to be harmed by smoking. Lung cancer, which is the leading cause of cancer deaths in men and women, is mainly caused by cigarette smoking. Secondhand smoking causes approximately 2 percent of lung cancer deaths each year. It causes respiratory disease, Sudden Infant Death Syndrome (SIDS), middle ear disease, and asthma attacks in children.
Each year more than 8 billion people are diagnosed with cancer all around the world. Everyone knows that cancer is a disease but what exactly is it? Cancer is not just one disease, there are actually more than 100 different types of cancer. Cells from any part of the body can become cancer and spread. Some types of cancers are more common than others. In order to understand what cancer is, it’s important to know how healthy cells function. Healthy human cells grow and divide in order to produce more cells when the body needs them. When the cells becomes damaged, it dies and gets replaced with a new cell; this process is called apoptosis. Unlike healthy cells, cancer causes the cells to grow out of control. The damaged cells survive and the
Cigarettes not only contain harmful substances, but they also can cause erectile damage. dysfunction in men and illnesses such as cancer and lung disease (http://www.americanheart.org/presenter.jhtml?identifier=3009767). Cigarettes are full of substances that are harmful not only to the smoker, but also to those around him or her. Smoking not only harms the smoker, but also those around them. For years it had been thought that smoking only affected smokers and non-smokers were not at risk at all, but after years of research it.
Tobacco can lead to someone losing limbs and can also cause diabetes. “For every person who dies from a smoking-related disease, about 30 more people suffer with at least one serious illness from smoking.... ... middle of paper ... ...
Most people would think that cigarette smoking can cause many health issues and diseases after looking at the ingredients used, and they are right. Periodontitis, Peptic ulcers, Erectile dysfunction, Chronic obstructive pulmonary disease, Cancer, and cardiovascular disease are just a few of the diseases that can be caused from smoking cigarettes. Smoking may also increase the chance of heart disease, stroke, atherosclerosis, and peripheral vascular disease. Tobacco has also been linked to Buerger 's disease, Oral disease and some infection throughout the body has also been caused by smoking
