Cancer is one of the biggest killers around the world. In America alone, 25% of all deaths are related to cancer.
Many people think of cancer as a single problem but in fact, it is a number of problems spread throughout the body. Generally speaking, if cancer is caught in the early stages of development, it can be treated and cured.
Although there are several different types of cancer, the most common ones are Lung, Prostate, Breast, Testicular, Skin and Colon cancers.
Genes control the multiplication and growth of cells. If these genes are defective in the first place, then the cells will not be able to grow or divide properly. As a result of this abnormality, cancerous cells are born.
There are a number of factors which cause cancer. Factors which are controllable by humans are smoking, toxic elements and radiation. These can be controlled to some degree and therefore it would be wise to avoid them by changing lifestyle habits. However, there are certain elements which are outside our control. These include mutation and inherited DNA.
As a result of studies conducted by the American Cancer Society, more than 180,000 people have died as a direct result of smoking. Another 200,000 people have died due to lack of changing lifestyle habits. Obesity, laziness and malnutrition can have an effect on the growth of cancer. Needless to say, cancer has risen by more than 50% since 1995.
Let's take a look at some of these cancer causes in more detail.
Smoking: The most prevalent and easily avoidable type of cancer is the one caused by the use of tobacco. This includes the use of cigarettes, cigars and pipes. Even though smokers are addicted to nicotine, the fact that 200,000 people die every year due to smoking caused cancer should be enough motivation to quit. Some experts say that cessation of smoking can increase lifespan by up to 20 years.
Although nothing has been proven, studies indicate that stress may also be a contributing factor to cancer. Many cancer patients are also employed in stressful jobs. Some theologians believe that stress lowers the bodies immunity to cancer.
Exercise and Healthy Eating: Healthy eating and exercise is universally known to be beneficial in many aspects. But, many people don't know that food full of nutrition can reduce the risk of cancer. Specific foods such as fruit and veg can help prevent cancer whilst fatty foods such as meat can increase the likelihood of cancer.
Skin cancer can easily be avoided by simply listening to good advice. Wear sunglasses, hats, sun cream and other sensible items of clothing to avoid the onset of this type of cancer. Although this may seem like common sense, more than one million people have been diagnosed with skin cancer in a single year.
In summary, some cancers can be avoided. New research and studies are being conducted all the time. So, rather than concentrating on how to treat cancer patients, maybe we should all be looking for more ways to prevent the cancer in the first place.
