What is early detection or screening (screening) of a type of cancer?

Early detection or screening for cancer is the process of finding a certain type of cancer at an early stage even before he can cause any symptom. In some types of cancer, your doctor can evaluate which group of people has increased risk of developing a specific type of cancer because of family history, because of diseases that already had or because of the habits that have, like smoking, consume alcohol beverages or high-fat diet.

This is called risk factors and people who have these factors belong to a risk group. For these people, the doctor may suggest a particular test or test for early detection of cancer and what that should be repeated frequently this test or exam. For most cancers, the earlier (as earlier) cancer is diagnosed, the greater the chance of fighting the disease.

What is the evidence that early diagnosis of colon cancer?

The digestive tract consists of several parts, beginning with the mouth through the esophagus, stomach, small intestine, large intestine or colon, rectum and terminating at the anus. The colon and rectum have the function of absorbing water with the food we eat and transform the mass of ingested substances and is not utilized by the body in feces to be eliminated. These two portions of the digestive tract are very similar as regards the litter that lines the inside and its function. Thus, tumors that affect these regions are called, usually, Colorectal cancer, and treated as a single disease.

These tumors can be diagnosed early in several ways. The test Fecal occult blood testing and investigating the intestine from the inside, such as colonoscopy, sigmoidoscopy and radiopaque enema (or barium enema) tests are most often used for early diagnosis of this tumor.

Set random nutritional requirements of a cancer patient is an impossible task, since each patient by age, sex, type of cancer and medical history is a particular case. But we can talk about the advice in nutrition, as general guidelines that should always be confirmed with the oncologist.

Cancer treatment and the disease itself produce states of malnutrition in the patient, which directly affects their quality of life.

Consider the general nutrition advice for cancer:

• Fats: As cancer patients often experience fat loss and muscle mass, it is recommended that the daily calorie intake is at least 25% of everything consumed.

• Protein: protein consumption stands at 15% of daily intake, for example, should consume 1.5 to 2 grams of protein per weight of the person. A 70 kgr should consume between 105 and 140 g of protein per day.

• Fiber: is so important for those suffering from colon or rectal cancer because it has a protective effect.

• Carbohydrates: the right amount is between 50 to 60% of daily intake for an average adult.

Each of these values may be altered in their rate, because each patient has a table space and its particular body reacts to disease. Nutrition should be tailored to each patient, with appropriate medical monitoring.
