Causes of Cancer

There is no single reason for cancer. Cancer can be caused by various factors, and the causes of cancer are still largely unknown. However, scientists have been able to determine the possibility of cancer in the body because: Carcinogenic factors There are specific factors in the environment that cause cancer and are known as carcinogens or "carcinogens", which increase the chances of people getting cancer when exposed. Tobacco smoking, pollution and asbestos are examples of carcinogens that may cause cancer to some people. Genetic readiness Some people have more genetic predisposition to develop certain types of cancer, especially if there is a family history. Certain types of cancer, such as retinoblastoma, are caused by genetic mutations. What are the risk factors? Although there are many types of cancers that are not specifically known, scientists have been able to identify the risk factors for certain cancers, which are known to increase the likelihood of these species developing. Examples of risk factors (For example, if you are a woman and your family member (your mother, sister, aunt, grandmother, grandmother) has been infected with breast cancer, this may increase your risk of infection. Unsafe exposure to pollutants or radioactivity. Does this mean that a person with risk factors will have cancer? No, this is not certain and can not be known with certainty. For example, you can not say that a person who goes out too much in the sun without protection (like wearing a hat or putting on a sun visor) will have cancer definitely, but means that the chance of cancer will be greater compared with people who are keen to take precautions before exposure to the sun . What if a person does not have any risk factors? Unfortunately, cancer may affect people who do not have any risk factors. However, people who follow a healthy lifestyle can reduce their risk of developing 40% of cancers, so your health is actually in your hands.
