Sun Radiation Cancer Carinogens Smoking Pesticides

Many specialists agree that those individuals that develop cancer at some point throughout their life that they have came in direct contact with a carcinogen, otherwise described as a cancer causing agent. Many oncologists further believe that developing a malignancy within your system can largely be attributed to genetic/hereditary factors. These carcinogens will viciously attack the affected group’s moral cells, thus causing one of them to become malignant in nature. Oncologists, while most of them at least, believe that cancer starts this way, these abnormal changes in a single cell. These negative implications then continue to spread to the cell’s descendent cells. Some carcinogens i.e. environmental carcinogens can be inhaled through the nose or mouth. Some attack the affected’s skin i.e. skin cancer. In most cases there is more than one attributable cause to someone being diagnosed with cancer, i.e. both exposed to cigarette smoke, pesticides, or poor diet. At the onset of cancer research, scientists would expose the very same environmental carcinogens that we are exposed to animals. It was widely believed that if the animal develops cancer, then the probability of humans getting cancer from these exact same substances. Most lab conclusions have suggested that there are two main groups of carcinogens that can encourage cancer within a human body; these are being exposed to a variety of chemicals, as well exposure to radiation.

Chemicals: Researchers over the years have specified, and compiled detailed lists of thousands of dangerous chemicals, in large part many of them carcinogenic. If these chemicals become widespread in a given populations water/food supply, the environment, as well in home or in the workplace, can incite cancer cell development within an affected individual. Food additives for instance, are added into our food supply, through processing systems, or through agriculture work i.e. spray on foods to keep unwanted pests from damaging or infected crops. Pesticides, often used cosmetically, as well insecticides used in the aforementioned example, have been linked to developing leukemia, and liver cancers, especially in children and seniors, the latter with debilitating immune systems. Other chemical like, environmental carcinogens would be cigarette smoke; common industrial chemicals i.e. air fresheners; many natural food chemicals; as well chemicals found in drugs.

Cigarette smoke is the leading preventable cause of cancer in Canada, followed by poor dietary habits. Smoking alone kills thousands of Canadians each year. Even being exposed to second hand smoke puts your health at risk. In British Columbia alone, 140 people die annually as a result of being directly exposed to second hand smoke. Some chemical carcinogens include asbestos, high levels of lead etc.

Radiation: Some types of radiation can incite cancer development in people directly exposed to these radiations for long periods of time. The scientist, Marie Curie, had died from her increased exposure to radiation over the period of her scientific work. For instance, those who get too much sun can develop skin cancer from being exposed too long to the suns UV rays. Skin cancer is currently the most diagnosed cancer in Canada with over 70,000 new cases per year; most often occurring is the non-melanoma skin cancer.

Viruses: Many experiments have suggested that certain diseases can inadvertently lead to cancer development. For example, cirrhosis of the liver can lead to certain types of cancer growth in the liver.
