In 2012, 13% of the world population has lung cancer. It is a disease known by people that it is incurable but what is cancer? Cancer is a disease cause by abnormal cell division and the abnormal cell can also invade other tissues. As the cells builds up it can create tumors and expand. When the tumor gets to a certain size, it may affect other organs as it may press on them. People may not realize the causes of cancer but the causes often involve our daily habits. From genetic heritage to the food we eat are all closely related to the risk of having cancer. Although preventing cancer is not possible, there are stills ways to reduce the risk of having cancer. It includes small changes in diet or lifestyle.
Causes of cancer-
Infection of viruses and bacteria can cause cancer. The infection can affect one’s body in several ways. It can lower a human’s immune system whilst with lower immune system the body cannot prevent some kind of cancer.

Eating more vegetables and fruits are part of a healthy diet. Both vegetables and fruits are high in fibre, minerals and vitamin. It can reduce the risk of having mouth cancer and throat cancer. It is recommended that 5 portions of vegetables should be taken a day. Secondly, it is recommended to eat wholegrain food. Wholegrain foods are food with unprocessed grain. Brown rice and grainy bread are high in fiber that reduces risks of having bowel cancer. It also contains antioxidant that lowers blood cholesterol level. By avoiding eating too much red meat and processed meat can also lower the risk. It reduces the amount of harmful chemicals. With less of these chemicals, there is less chemicals to develop cancer causing cells. Eating food with less salt is also helpful. It can lower the risk of damaging the stomach or inflammation of stomach. Not only lowering the risk of harming the stomach but also prevents bacteria that cause stomach
According to Michael Pollan, the best way to eat healthily is to grow fresh vegetables. Pollan’s documentary effectively contributes evidence that eating mostly plants is naturally beneficial and prevents disease. In an experiment conducted by Steven O’Keefe, data reveals that colon cancer is more common in the United States than in Africa. The documentary simply states that the people of Africa eat mostly plants. Michael Pollan suggests that the lack of plant foods in the American diet causes a lack of fiber intake. After collecting this data, Steven O’Keefe swaps the diet of an African and American. This study eventually exposed that more vegetables in a diet can support colon health and prevent colon cancer. When stated so logically, Michael Pollan convinces the viewer that eating “mostly plants” is a necessary change for our health. He argues that historically, eating plants have been naturally healthy to various cultures and has potential to raise the well being of America.
Current dietary recommendations emphasize increasing the daily consumption of fruits and vegetables from diverse sources such as citrus fruits, cruciferous vegetables, and green and yellow vegetables (Heber, 2002). A healthy diet along with proper life style such as regular physical activity can prevent the majority of cardiovascular disease.
Oral cancer can be prevented. Cancer prevention is the action taken to reduce one's risks of getting cancer. Preventing oral cancer can be accomplished in just a few easy steps. Things that increase the chances of getting oral cancer are called a risk factors and things that decrease the chances of getting oral cancer are called cancer protective factors. One may be able to avoid some risk factors, but others cannot be avoided, such as inheriting certain genes that may cause cancer can not be avoided, but changing ones eating habits, not smoking and not chewing any types of tobacco is likely to decrease one's chances of getting oral cancer. There is no way of fully preventing oral cancer, there are only ways that can decrease the chances of developing oral cancer. One way to reduce the risk of developing oral cancer is to brush at least two times a day and floss at least one time a day. Both heavy and regular alcohol...
Diagnosed with lung cancer, now what!? Time to do some research. Lung cancer is the number one cause of deaths in males and females. The causes, diagnosis, and treatment of lung cancer have advanced recently with new technology available to scientists and the medical profession. Lung cancer develops when the cells grow abnormally and tumors form instead of healthy lung tissue. It can take place in one or both lungs, normally the cells that line the air passages. Not all tumors are cancerous, the ones that do not spread are benign tumors. The more tumors that develop in the lungs will cause the lungs to work less efficiently. The metastatic tumors spread to other parts of the body passing through the blood stream or lymphatic system.
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 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. ...
All cancer has a genetic basis. It is triggered by mutations in the genes of a cell which then cause the cell to abnormally reproduce. Many of these gene changes are caused by random mutations when the cell is dividing. It only takes one cell mutating to cause cancer. There are no symptoms for the beginning of cancer and only five to ten percent of all cancers are caused by parents passing down genetic mutations to their children. The remaining are caused by environmental changes (Douglas).
Lung cancer has been around for hundreds of years. Lung cancer is also the most common cancer. Death is almost absolute if not caught in its early stages. Lung cancer is hard to find because there aren’t symptoms in the early stages. Lung cancer found early enough can be stopped before it spread to other parts of your body. This isn’t definite because cancer can be dormant until later in life and it can be worse than before. Lung cancer can be avoided if you if you make the right choices and take right
Saturated fat and cholesterol and an increased risk of heart disease. Fiber and a reduced risk of cancer. Fruit, vegetables and grain products that contain fiber and a reduced risk of heart disease.
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.
Cancer is defined as where the abnormal cells are divided without any control and they are able to invade into tissues. At times cancer can be cured right away once it is detected through treatments that the doctor recommends, but at times cancer cannot be cured based on what stage the cancer is at. It is very important that every individual gets a physical check up to see if they are diagnosed or detected with any sort of cancer or disease. There are 100 types of cancers out there, but the type of cancer that I will be focusing on is Lung cancer. One of the controversial issues on a lung cancer is the ...
The first thing I am going to talk about is Cancer. There are certain foods that you should try and avoid in order to decrease your risk of getting cancer. According to the Mayo Clinic they suggest that you eat plenty of fruits and vegetables. Along with other foods that will come from plant sources. Whole grains and beans are another good source of food that you should eat. They recommend that we should limit our fat intake. Eat lighter and leaner by picking out fewer high – fat foods, especially the ones that are from animal ...
Eating vegetables three or more times a day can provide health benefits. Research has shown that, individuals who eat less than three servings of vegetables each day, compared to those that eat more than five servings have a relatively twenty percent lower risk of developing coronary heart disease or stroke. Vegetables provide nutrients that are fundamental for the health and upkeep of our bodies. These days, most vegetables are grown all over the world as climate permits. Vegetables can be eaten either raw or cooked and play an important role in human nutrition, being mostly low in fat and carbohydrates, but high in vitamins, minerals and fiber.
Weight control is a concern of most individuals, and as a person ages weight becomes more difficult to manage. When this problem occurs, the majority of people look to exercise or diet change for answer. In order to manage one’s weight a person must eat fewer calories than they expend, which can be completed by consuming foods with lower energy density, high fiber, and high water content. When it comes to research and diet it is common knowledge that fruits and vegetables are superior in nutrition when compared to the other food groups. According to the Center for Disease Control, “consuming a diet high in fruits and vegetables is associated with lower risks for numerous chronic diseases including cancer and cardiovascular disease” (Can, n.d.,
