The only thing that distinguishes different cancers is their appearance, not their nature, so the best way to learn is to avoid the factors that cause the disease and to better prevent it. And, no matter what type of cancer is considered, the most successful way is preventing contact with carcinogens. Early detection is a key point in successful treatment. You may know that all of the medical system's efforts on this disease are based on early prevention and diagnosis. As a result, identifying ways to prevent cancer in the process can be very effective. Because cancer is a disease that about 30 to 40 percent of all cases of which are preventable with proper nutrition and weight control, exercise and lifestyle changes, and due to the high cost of treatment and the failure of many of them, the most appropriate treatment is prevention.
