Nutrition And Cancer : The Main Causes Of Cancer

The origin of cancer within a person could be a result of multiple variables. Cancer could simply be a malfunction within the body. All living things are composed of cells. Cells house the genetic makeup of a person: deoxyribonucleic acid, or DNA. The human body is composed of trillions of cells which constantly divide to replace old or damaged cells (“The Cells”). For cells to divide, enzymes within the cell must duplicate the DNA. Mistakes in copying genetic code are common. This division of cells usually occurs in a consistent and controllable manner as the cell has the ability to check its DNA for errors and self-destruct if an error is potentially harmful; however, not all mistakes are caught. If the mistake in the DNA is not noticed and taken care of, the cell can develop and begin to behave abnormally. It may gain the ability to stimulate its own growth and ignore signals to stop. When this happens, a cluster of abnormal

The topic of research is important because it relates to how diet and exercise benefit terminally ill cancer patients. Several researchers studied and conducted trials for the major types of terminally ill cancers, including palliative cancer care. The researchers tried to help improve the patients’ health through diet and exercise programs which included nutritional counseling, energy or protein intake, or food and supplements. However, I learned that depending on the person or in this case the groups, that diet and exercise could benefit your overall health and well-being. After learning about diet and exercise and how it helps cancer patients, I recommend that you should always try to eat healthy meals throughout the day and incorporate

Heredity also plays a role in the development of cancer. If a person’s relatives have a history of cancer, then that person has a higher risk of developing cancer. Genetic variations, particularly those influencing how the body responds to carcinogens, may create a greater vulnerability to cancer.

Cancer can be caused by many factors. Some of these factors include: Genetics, Tobacco, Diet, Physical Activity, Sun Exposure, Radiation, and Other Carcinogens. Some types of cancer run in certain families, but most cancers are not clearly linked to the genes we inherit from our parents. Most people are unaware about just how much tobacco use accounts for of cancer related deaths. Even though cigarette use has decreased significantly there are still tobacco products that are highly popular. Vape pens, or electronic cigarettes are on the rise among former smokers and teenagers. Although believed to be healthier there is still nicotine, and unknown substances in the flavored liquid. Many people are also very unprepared when it comes to being outside for prolonged periods of time. Sunscreen is a necessity in order to protect oneself from the harmful UV rays. It is also very important to have regular checkups from a

Subsequently, each cell that develops from the fertilized egg will receive this mutated gene. He states that for a cancer to manifest, two mutations must occurs. In hereditary cancers, the person inherit one mutant gene. The second mutation occurs as result of a mitotic error during the many cell division that occurs in the person's lifetime. In sporadic cases both mutation occur in the person's lifetime. In sporadic cases both mutation occurs after fertilization an are acquired much later in life. From this Kudson conclude that hereditary cancers manifest at younger age and there is a higher incidence of multiple tumors, where sporadic cancers occur late in the life and usually only a single tumor occurs. The principal causes of cancer appears to be environmental agents. A good example of this is skin cancer. The condition has increased among fair skinned people who expose themselves to too much sunshine, while being very uncommon among dark skinned races (knudson 1971, cited in Ormiston, 1995). Therefore, most genetic alteration are acquired through our life time from environmental carcinogens with only a small percentage been inherited. However, inherited cancers are very important as it appears that the genes responsible for, hereditary cancer maybe the same as those involved in sporadic malignancies.

While there are several biological factors that have the ability to lead to cancer, genetics is the most currently researched. A study done by Bharaj, Scorilas, Giai and

Since cancer is a multifactor disease, there is not a specific cause for the development of it, and there is not a specific way of preventing it. However, since 30 to 40 % of cancers are influenced by diet, it make a lot of sense to follow diets are thought to be protective against cancer. Some of the characteristics of theses diets are:

Lung cancer is a genetic and acquired disease. Lung cancer is genetic because cancer in general is caused by changes to the genes that control the way our cells function, especially how they grow and divide. All of these changes include mutations in the DNA that makes up our genes. Genetic changes that increase cancer risk can be inherited from our parents, if the changes are presents in germ cells. Which are the reproductive cells of the body, those are the eggs and the sperm. Lung cancer is also acquired because as the result of errors that occur as cells divide a person’s lifetime or exposure to certain chemicals. Some examples of these chemicals are found in tobacco smoke, radiation, UV rays from the sun that damage DNA. “In general, cancer cells have more genetic changes than normal cells. But each person’s cancer has a unique combination of genetic alterations.” Some of these changes may be the result of cancer, rather than the cause. As the cancer continues to grow, additional changes will occur. Even within the same tumor, cancer cells may have different genetic changes.

Adults can get cancer more ways than children. Environmental factors and lifestyle choices play a major role in adults getting cancer. A major factor for cancer in America is obesity. Obesity will soon take over tobacco as the number one risk for cancer. Obesity causes colon, rectum, kidney, pancreas and other types of common cancers. Overexposure to UV lights increase the risk of melanoma. Finally, if a woman is exposed to estrogen, she is more likely to get breast

Cancer occurs as an result of mutations in the genes responsible for regulating the growth of cells and keeping them healthy. Normally, the cells in our bodies replace themselves , healthy new cells take over as old ones die out, but, over time, mutations can “turn on” certain genes and “turn off” others in a cell. That changed cell gains the ability to keep dividing without control or order, producing more cells like it and forming a tumor.

Even though it is unknown why cancer happens in some people and not in others, heredity seems to have an effect in some forms of cancer. Because of this, family history may be

n the magazine article “Reducing the Risk of Cancer by Healthy Food Choices and Physical Activity” by Tim Crowe, readers learn how to prevent cancer through physical activity, dieting, and lifestyle changes. Physical activity, such as walking, swimming, running, and cycling, helps to prevent cancer by “20 to 40 per cent” and being active will also protect against a plethora of diseases. While activity is a great fighter against cancer, dieting, “a combination of good eating habits and food variety,” gives plenty of ways to prevent cancer and even make someone feel better about him or herself. In order to adapt to the lifestyle changes needed to prevent cancer, the World Cancer Research Fund, “the peak worldwide body tasked with studying cancer

Chemotherapy is the most used drug or combination of drugs in the United States primarily to combat malignant tumors at the cost of even damaging the healthy cells. The purpose of chemotherapy is to either slow down or halt the spreading of the cancerous tumor. Yet, there is another way that is not widely used to fight against malignant tumors and that is the holistic approach. The holistic approach is showing promise to combat cancer and that is to eat organic fruits and vegetables, take natural supplements and to eliminate refined sugars and oils to name a few. With the two different ways to combat cancer in mind, it would be beneficial for cancer patients to use the holistic approach instead of chemotherapy since it does not damage any of

Lifestyle and dietary changes, as well as nutritional and herbal supplements can be very helpful and improve the patient's quality of life while going through cancer therapy. Many factors play a role in determining the right treatment strategy, from an alternative standpoint. The type and stage of cancer for example, the patient's constitution,

There are many ways that you can get cancer. You can get cancer from smoking, sunlight, your diet, mold, viruses, and inheritance. Out of those factors, the most common cause of cancer today is smoking. All cancers are genetic because they are caused by the mutations that happen to the gene. Some common cancers that are
