How to steer clear from cancer

cancer can affect anyone, male or female and of various age groups.
Various causes and risk factors of cancer has also been frequently discussed. However, it is almost always impossible to prove what caused the cancer that occurs in a person. Because cancer has several possible causes.
For example, in a smoker can lead to development that leads to lung cancer. However, in another case to someone who is not a smoker, still has a risk factor for lung cancer due to air pollution or radiation.
For 90-95 percent of cancer cases are caused by environmental factors. While the remaining 5-10 percent of cancer cases are caused by genes.
Environmental factors that increase cancer risk factors rather than just pollution. Environmental factors, among others:A. Cigarettes or tobacco, about 25-30 percent of cases2. Obesity, about 30-35 percent of cases3. Infection, approximately 15-20 percent of cases4. Radiation, both ionizing and non ionizing radiation, up to 10 percent of cases5. Stress6. Lack of physical activity7. Environmental pollutants
There are 3 ways to minimize the risk of cancer, among others, as quoted by WebMD, Sunday (10/16/2011):
A. Know your family health history
"Finding out about your family history, can tell if someone has a high risk of cancer or not," said cancer researcher Beth Y. Karlan, MD. If you can find out the status of the risk of cancer in the family can focus on prevention.
2. Regular health checksRegular health checks are very useful for early detection of disease, not just cancer. Early detection will be very useful for the successful treatment or cure for a disease or disorder.
C "ek such health, such as a colonoscopy examination when aged over 50 years," said the professor of obstetrics and gynecology Carolyn Runowicz, MD.
According to the American Cancer Society is also doing a routine pap smear for women, who started 3 years after first sexual intercourse or no later than the age of 21 years. Also routinely perform mammography after the age of 40 years.
3. Stay away from obesity and examine the body mass index (BMI) periodically"Get used to examine BMI regularly and keep it under the number 25, in order to avoid being overweight," says Karlan.
Because obesity has been considered a risk factor for cancer and other serious illnesses. In addition to weight loss, regular exercise can also reduce levels of estrogen in the blood. Estrogen levels in the blood may help reduce the risk of breast cancer.
BMI categories are:Thin categories: BMI value of less than 19Ideal Category: Value BMI 19 to 24.9Fat Category: Value BMI 25 to 29.9Category Obesity: BMI value equal to or more than 30
How to Calculate BMI
How to calculate BMI by squaring the value of height (in meters).Then the weight (in kilograms) divided by the square of the height.
For example one 30-year-old woman weighing 60 kg and height 160 cm (1.6 feet).How to count are:The first time squaring height 2.56 1.6 X 1.6 results. Then the weight divided by the product of the heights of 60: 23.43 2.56 results. Mean BMI values ​​of 23.43 for women and belong to the ideal / normal.
