Cancer is when the body begins to produce abnormal cells, or:
...numerous distinct diseases characterized by abnormal cell growth and differentiation.
Strategies to prevent cancer are becoming more publicized all the time. One form of prevention that has been available to the public for many years is linked to the incidence of cancer from smoking, or being around someone who smokes. The best thing to do is stop smoking, or never begin, and remove yourself from others who smoke: secondary smoke can cause cancer in non-smokers.
Attention to diet is another major way to prevent cancer. Eating a lot of fruits and vegetable, and avoiding foods high in saturated fats are factors being tested in clinical trials to determine if they might have a pronounced effect on the incidence of cancer. Studies regarding vitamins, soy and minerals are also being conducted.
Eighty to ninety percent of all cancer is linked in some way to the environment, and in these numbers, between thirty and forty percent of these incidents of cancer are due to diet. It is suggested that reducing fat intake, limiting consumption of red meat, alcohol, and sugar may be effective in limiting the chances of developing cancer. "Processed meats, energy-dense foods, and mouldy grains" should be avoided as well. It is better to eat foods of plant-origin. It is believed that nutrients and antioxidants are instrumental in preventing cancer.
The Mayo Clinic also makes additional recommendations. Keeping a healthy weight and including some exercise on a daily basis is good for fighting cancer. Avoid exposure to the sun. Immunization, and as well as practicing "safe-sex" and not sharing needles are helpful steps in staying cancer-free. Finally, people should look to early detection as a way to fight cancer. Cancer screenings are important; it would be wise to speak to one's doctor regarding steps that can be taken in the fight against cancer.
