Recommended: Research about tobacco use and lung cancer
“Cancer is an intricate and potentially lethal collaboration of genes gone awry, of growth inhibitors gone missing, of hormones and epigenomes changing, and rogue cells breaking free.” There are many causes of cancer including genetics, tobacco, physical activity, UV exposure, radiation, and one's environment.
A majority of cancer cases are caused from cells that get mutations, but other times they happen randomly as the cell divides and makes new cells. According to the American Cancer Society, “Some acquired mutations can be caused by things that we are exposed to in our environment, including cigarette smoke, radiation, hormones, and diet. Other mutations have no clear cause, and seem to occur randomly as the cells divide.” Meaning that sometimes cancer just happens, and you have no control over it, and other times it is caused by something you can have some control over. For example you have no control over how your cells divide, but you do have control over something like tobacco smoke. People can also have gene variants, meaning the gene is different than normal, but it isn't a mutation. Gene variants can indirectly cause cancer because they have the possibility to affect hormone

An article from the American Cancer Society states that, “Cigarette smoking accounts for at least 30% of all cancer deaths.” (Source 1) Meaning that it has been proven, smoking puts you at huge health related risks. According to the American Cancer Society, “ Besides lung cancer, tobacco use also increases the risk for cancers of the mouth, lips, nose and sinuses, larynx, pharynx, esophagus, stomach, pancreas, kidney, bladder, uterus, cervix, colon/rectum, ovary, and acute myeloid leukemia.” After hearing this I believe it is safe to say tobacco use is one of the most preventable cancer carcinogens there are. Along with tobacco use, diet and physical activity is another one of the main preventable
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.
I have chosen to write about the constellation Cancer (The Crab). I chose Cancer because it is one of only a handful of constellations that I am actually able to identify in the night sky. Cancer is one of the twelve Zodiac constellations; people whose birthdays fall between June 21st and July 22nd have Cancer as their sign. Cancer is the Latin word for crab, and despite the fact that the constellation looks more like a lobster then a crab, it is still referred to as a crab. The constellation is visible from the northern hemisphere from late winter to early spring.
I have elected to transcribe my proposal argument on issues regarding cancer chemoprevention. I selected this topic because reasonably minute devotion has been given to cancer chemoprevention research in ethical writings, particularly in relation to the huge quantity of moral studies in cancer treatment exploration. Cancer chemoprevention trials test the ability and care of medicinal agents in averting cancer before its manifestation. I believe that phase III chemoprevention issues can be less prevalent by simply ensuring enhanced communication and etiquette between researchers and investigators.
The cancer cells from gene-mutation. Scientists now know some of the risk factors for lung cancer can cause certain changes in the DNA of lung cells. These changes can lead to not normal cell growth and, sometimes, cancer. DNA is the chemical in each of our cells that makes up our genes and how our cells function. People usually look like their parents because they are the source of our DNA. But DNA affects more than how we look; it also can affect our risk for developing certain diseases, including some kinds of cancer like lung cancer etc…Some people inherit DNA mutation from their parents that greatly increase their risk for developing certain cancers.
Smoking is the most preventable cause of death in our society. During 1995, approximately 2.1 million people in developed countries died as a result of smoking. One tobacco use is responsible for nearly one in five deaths in the United States. Lung Cancer mortality are about 23 times higher for current male smokers and 13 times higher for current female smokers compared to a lifelong never-smoker.
Cancer starts when cells in a part of the body start to grow out of control. Cancer cell growth is different from normal cell growth. Instead of dying, cancer cells continue to grow and form new, abnormal cells. Cancer cells can also invade (grow into) other tissues, something that normal cells cannot do. Growing out of control and invading other tissues are what makes a cell a cancer cell. Cells become cancer cells because of DNA (deoxyribonucleic acid) damage. DNA is in every cell and it directs all the cell’s actions. In a normal cell, when DNA gets damaged the cell either repairs the damage or the cell dies. In cancer cells, the damaged DNA is not repaired, and the cell doesn’t die like it should. Instead, the cell goes on making new cells that the body doesn’t need. These new cells all have the same abnormal DNA as the first cell does.
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.
Breast Cancer, as well as other forms of cancer, scientists do know how it occurs, but they do not know an exact cause. There are some genes in our body called oncogenes, genes that have potential to cause cancer, that increases the speed of cell division while other genes such as tumor suppressors, cause the cells to die at the correct time. Mutations that occur in the DNA, which “turn on” the oncogenes or “turn off” tumor suppressor genes, will cause some of the cells to be cancerous in the breast("American Cancer Society"). Also, Breast Cancer can be increased by inherited gene mutations and acquired gene mutations. The risk of Breast Cancer can be increased dramatically, through the inheritance from parent to offspring, if a mutation occurs. For example, if a suppressor gene, such as BRCA, forms a mutation, then it is likely to be passed to future generations. This gene no longer suppresses abnormal growth, therefore there is a higher chance of cancer being developed. Even though Breast Cancer can be inherited it is more likely to be acquired through one breast cell. The acquired mutations could be a result of of radiation or cancer-causing chemicals. ...
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.
Over the past few decades, cancer has become a very prominent disease. There are many different types of cancer and many different causes of the the disease. Most cancers are caused by a genetic mutation. The most common type occurs when a cell is divided. Proto-oncogenes, which are alleles in normal cells, mutate to form oncogenes.
Tumors are formed by the alteration of the body’s own cells. This can be caused by environmental factors such as radiation, like UV exposure, chemicals or viruses 1. These can disrupt genes that control growth and cause an increase in cell division and proliferation. Proto-oncogenes are those genes that control normal but essential cell processes that keep cell growth and death in check. Two important categories are apoptosis genes, which regulate cell death, and tumor suppressor genes, which decrease cell propagation 1 . If these genes were mutated to the point where they cannot produce a functioning protein, cell division would continue far past what it was supposed to and unhealthy cells would be allowed to live and continue to multiply. This is what creates a malignant tumor. Certain conditions in the body can also promote the growth of cancer cells. One of these is a deficiency of natural killer (NK) cells, which are able to kill cancer cells by creating a pore in the cell membrane with perforin and releasing granzymes into the cell. Low levels of perforin allow for tumor growth 1. Chronic inflammation can also ...

Approximately one in two lifetime smokers will die from their habit. Half of these deaths will occur in middle age. The most common of the diseases caused by smoking is cancer, of course. Not only is it a cause of lung cancer, but cancer of the larynx, and the esophagus, and it contributes to the development of cancers of the bladder, pancreas, and kidney. Lung cancer comes from the tar in the cigarettes.
What is cancer? Cancer is the abnormal and uncontrolled growth of cells that if left untreated can ultimately cause death. The word cancer came from the Greek word for crab, karkinos. The early Greek physicians who first described cancerous tumors had no notion of their cause or true nature, but they were struck by the resemblance if some invasive tumors to crabs: a hard mass with a claw like extensions and an aggressive nature. Cancer causes about 550,000 deaths a year. Although many people believe that cancer is one disease, there are actually in fact over a 100 different forms of cancer. Some cancers can be cured, but not all of them have cures. Even though each type has its own characteristics, all cancers share one common characteristic, and that is the abnormal cell growth. These abnormal cells form tumors that invade normal tissues and disrupt body functions. Tumors are cancerous when they spread to other parts of the body. These types are called malignant, while tumors that do not have the potential to spread are called benign.
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
