Cancer occurs when abnormal cells uncontrollably divide and invade other tissues. As a result, cancer cells can spread to other body organs and tissues through the blood and lymph systems. According to the National Cancer Institute, there are more than 100 types of cancer. Researchers have identified many cancer-causing agents. Most cancers can be prevented by making lifestyle changes, such as eating healthy, exercising, refraining from tobacco use and avoiding sun exposure.
Avoid Tobacco
According to the Southwestern Medical Center, tobacco, in the forms of chewing tobacco, cigarettes, cigars, pipes or snuff, is the leading cause of cancer deaths in developing countries. These include throat and lung cancer, bladder cancer, cervical and pancreatic cancer, and cancers of both the rectum and colon. Speak to a physician about therapies and medications to aid the transition from smoking. Protect children by not smoking in the car or home. Non-smokers should avoid secondhand smoke to decrease the risk of lung cancer.
Eat Healthy
The American Cancer Society reports that eating healthy reduces the risk for certain cancers. High-calorie and high-fat diets tend to lead to obesity and increased cancer risks. Eating vegetables and fruits helps to lose or maintain weight and provides vital minerals, vitamins, fiber and proteins needed for body immunity. The National Cancer Institute recommends at least five servings of vegetables and fruits a day. A diet high in vegetables and fruits may reduce a person's risk for stomach, colon, esophageal or lung cancer. Choose lean red meats, white meat or fish as often as possible. Limit alcohol consumption.
Limit Sun Exposure
The Mayo Clinic reports that skin cancer ranks as one of the most common cancers. However, it is also preventable. The American Cancer Society recommends that people avoid going outside during peak hours for radiation exposure, which is between 10 a.m to 4 p.m. When outside, wear hats and clothing to protect the legs, arms, ears and face. Use sunscreen and avoid tanning beds and booths, which emit dangerous ultraviolent rays that can damage the skin.
Exercise
The National Cancer Society states that being overweight increases a person's chance of developing uterine, colorectal or breast cancer. Maintain a healthy weight by eating a diet full of vegetables and fruits and remaining active. Exercise for at least 30 minutes daily to maintain a healthy weight and reduce the risk of developing certain cancers such as breast and colon cancer. Formulate an exercise plan that consists of walking, jogging, swimming or biking.
Regular Screening and Self-Examination
Screening tests, such as mammograms and colorectal exams, can save your life. The Southwestern Medical Center reports that regular screening and examination increases the chances of finding cancer and successfully treating it. Everyone should undergo a yearly physical to check various areas of the body for abnormalities, symptoms or signs of cancer.
