Recommended: Essay on environmental factors cancer
Genetics, environmental factors and random chance plays a role in a person’s likelihood of developing cancer because they are a huge part of a person’s health. There are some things that you can control and somethings you can’t control. Every choice you make impacts your health either good or bad. If you keep a healthy lifestyle, you can prevent some cancers. Genetics play a huge role in your likelihood of developing cancer. If your parents had Melanoma and you don’t have it, you are at a higher risk of getting it. Wear a lot of sunscreen and make sure to keep reapplying it to help decrease your chance of getting melanoma. Environmental factors can really impact your chances of getting cancer. If you live in a place that is always
I think the chapter that helps to support her main point the most is chapter four titled “Space.” In this chapter, she discussed a great deal about the geographic distribution of cancer as well as the environment of the people who are more likely to get cancer. This includes: job type, living location, and living surroundings. To expand on each, she states that workers with
Melanoma is an extremely important issue, as 75% of skin cancer deaths in Australia are attributed to melanoma, making it the most dangerous form of skin cancer in the country (AIHW 2010). The AIHW also states that Australia has the highest occurrence of melanoma in the world, with over 12,500 Australians being diagnosed annually, and having a recorded 1500 deaths each year. The Melanoma Institute of Australia states that melanoma is the “most common cancer in young Australians aged 15-39”, and that “rates have doubled in the 20 years from 1986-2006”. The incidence of melanoma is increasing more rapidly than any other major cancer. Owing to the high incidence and mortality rates of the disease in Australia, melanoma is the most life-threatening form of skin cancer in the country, making it a very serious non-communicable disease.
...tance. Things that may protect you from cancer are; a proper balanced diet and a strong immune system. Your body has a sort of, command center that controls the growth of skin. Sometimes the cell reproduction process goes wrong and the newly created cell is a mutation of the original cell. Most cell mutations do not survive long enough to become harmful but sometimes the genetics of the cell allows it to survive and the cell could become cancerous. Some things that make a cell cancerous are; it not being attached to the command center, when the cell doesn’t give notice to the signal sent to tell it to stop growing, and when the cell gains its own blood vessel network system. Cancerous cells can move around and take over other sections of the body which destroys the person. Cancer and heart disease and many other severe conditions are there for many years before you e
The skin is the largest organ in the body, so it isn’t surprising that skin cancer is the most common of all cancers. Melanoma is the least common form of skin cancer, affecting 4% of all cases but causing 79% of skin cancer deaths. The average age of people diagnosed with Melanoma is between 45 and 55, although 25% of cases occur in people under 40. About 10% of all people with melanoma have a family history of melanoma. You are at increased risk of developing melanoma if there is a family history of melanoma in one or more of your first-degree relatives like a parent, child, brother or sister.
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.
Over all, skin cancer is known to be a very common and dangerous cancer among the U.S.. Although there is no superior or particular cause known for it, it can be reduced by reducing radiation exposure from the sun and also tanning booths and beds. If not attempting to prevent it by staying out of the sun, and seeking not seeking shade and so forth, protection such as longer clothing garments that better cover the body as well as hats and sunglasses can help to eliminate direct exposure and reduce some of the damages that may occur. Certain amounts of sun light are healthy for the body as it provides vitamin- D which the body needs to maintain a healthy life style, though it is crucial not be over exposed as reverse side affects may occur, causing more harm than good.
Breast Cancer is a disease that can sometime lead to ovarian cancer and has caused a lot of women’s death. “About five to ten percent of breast cancer cases are thought to be hereditary, meaning that they result from gene defects called mutations inherited from a parent”. Related Risks early menstruation, oral contraceptives and child bearing 20 percent. (1)An environmental risk is that toxins can damage breast DNA. Over time damaged DNA can lead to cancer. Your risk of developing breast cancer increases as you get older. “1 of 8 breast cancer are found when women are younger than 45. 2 of 3 breast cancer are found in women age 55 years or older 75 percent greater chance”.(1) Breast Cancer can lead Peutz Jeghers syndrome the effects of Peutz Jeghgers is spots on your lips and in their mouths. Women with no children or who had a child after age 30 have slightly higher breast cancer risk. “Screening for breast cancer is early diagnosis increases chance of survival and annual mammogram after age 40”. Women who took Diethylstilbestrol while pregnant could have a slightly higher risk of developing breast cancer. Birth control peals also cause higher risks 40 to 50 percent for breast cancer risk calms down after they have stopped taking them.(1) Using combined hormone therapy after menopause increase the risk of getting breast cancer , it also increase women chances of dying from it. If you are over weight or obese after menopause greatly increase breast cancer risk 20 percent. Drinking alcohol can cause a major effect for you to start developing breast cancer the risk increase the more you drink. Tobacco smoke, Night work, Antiperspirants, Bras and Induced abortion. Breast cancer takes a lot of toll on women and men of all races and...
Your chances of getting cancer from exposure to a certain chemical also depends on different circumstances or conditions. How long and the frequency at which you are exposed to a chemical, the amount or concentration, your own personal "make up" or susceptibility, and age are only a few of the variables to be considered when calculating your risk. Some of these conditions you can control, some you cannot.
In the United States, starting from the first breast cancer case in 1930s to today, a woman's lifetime risk of breast cancer increases to one eighth (Gray et al.). Continuously increasing breast cancer rate has caused a lot of concerns among not only ordinary people but also scientists. For decades, scientists have been working on the causes of breast cancer in order to find the corresponding methods of treatment. However, only about 25% of the breast cancer cases got explained (Brody et al.); till today, heredity, lifetime exposure to environmental estrogen (the female sex hormone), and the dietary fat are the only major known causes (“Cover Story: Breast Cancer and Environment”). For the 75% unexplained breast cancers cases, scientists, through various of researches, have come up with several hypothetical breast cancer causes, in which synthetic chemicals and environmental radiations are the major ones.
To prevent new cancers from taking off, scientists look at risk factors and protective agents. Anything that increases your chance of getting cancer is called a cancer risk factor; anything that lessens your chance of getting cancer is called a cancer protective factor. Some risk factors for cancer can be averted, but many cannot. For instance, both smoking and inheriting certain genes are risk factors for some types of cancer, but only smoking can be avoided. Normal excise and a healthy diet can help reduces the chances, but do not promise.
Likewise, lung cancer affects people who have never smoked due to the presence of radon and household pollutants. Radon has contributed to 10% of all lung cancer deaths and is considered second to smoking. There is no way to predict who will get cancer, but inherited genetic risk factors make some people more vulnerable to carcinogenic exposures than others. Lung cancer starts whenever there is an uncontrolled growth of abnormal tissue cells that affect the normal function within the lungs. As these abnormal cells grow they form tumors which can block the oxygen exchange within the body. (Lungcancer.org, 2014).
Skin Cancer is caused by hereditary factors, overexposure to the sun, and weak immune systems. (“Skin Cancer” infotrac.com) One reason people tend to get skin cancer is when someone in your family has passed their genes down to you, known as hereditary. Normally hereditary is one of the causes in the development of melanoma. For all types of skin cancers, overexposure of the skin to UV radiation in sunlight is the most frequently blamed source of skin cancer. “Research suggests that sunburns received early in one’s childhood can lead to skin cancer later in life” (“Skin Cancer” infotrac.com). For example, when someone gets sunburned, you usually don’t know till ten to twenty years after and that’s why people don’t get skin cancer till they reach their twenties.
Since 1979 the diagnoses of cancer have gone up nearly 20% in a generation as there is more people smoking, drinking, obesity and unfitness (theguardian website, 2011, para. 1). There has been in increase of women with the diagnosis, the diagnoses have risen up by 50% (459 per 100,00), men have risen from 20,000 to 24,000 (the guardian website, 2011, para. 2). Socioeconomic class does have an effect in some cases as cervical and lung cancers are more common in poor people while rates of breast cancer and melanoma are higher in the wealthy (ScienceDaily website, 2008, para. 1). Demographics could also have some effect as those of the wealthier group have more exposure to UV by traveling abroad for the holidays (ScienceDaily website, 2008, para. 5). In regards to smoking, deprived groups continue to smoke while the wealthier groups have quit smoking (ScienceDaily website, 2008, para. 7). Researchers have linked cancer to not only demographics, socioeconomic class but also race and
Everyone is born with certain genetic mutations that make the them more likely to develop cancer in a later time in life. Though they might have a genetic feature, cancer will not develop unless triggered by environmental factors such as air and water pollution. As a matter of fact, my grandfather started smoking alongside consuming heavy amounts of alcohol around the age of 15, smoking and heavy alcohol intake have been considered as one of the potential causes of colon
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.
