The code of the European Commission against the cancer leaves absolutely of course the allowance is, together with the tobacco and the exhibition to substances carcinógenas, one of the most important factors related to the cancer.
Modifiable risk factors (factors associated with lifestyles)
During latest years numerous studies have been done on the relationship between diet and cancer, and, although results sometimes are contradictory, yes a direct relationship has been established between some tumours' appearance and food habits. In fact, certain dietetic guidelines can be more determinant in the appearance of some cancer types that the genetic inheritance. As a result, many cancers you can avoid if a healthy way of life is adopted.
In normal conditions the immune system detects and it destroys malignant cells (also known as carcinogenic or cancerous) with typical traits of behaviour and rampant growth. This system needs, to work in an optimum way, certain nutrients (basically vitamins and minerals) that they contribute a balanced diet. The malnutrition, this is, the lack not only quantitative, but also qualitative in the usual allowance, has repercussions negatively in the immune system, since it decreases its preventive effectiveness in the development of tumours.
Furthermore, the cancer affects directly the nutritional status, since it alters the metabolism of the body and it causes a loss of appetite. As for the metabolism, the demand of energy is increased (that is, more calories are needed) and individual changes are produced in the skills of the body to decompose carbohydrates, proteins and fats. All of this causes the loss of muscle and fat. The loss of the associated appetite with the cancer probably is the result of physical changes, but also can have to a psychological reply to the illness.
For all that it is necessary to do a good prevention, following some habits of correct diet, that is, adopting a healthy diet. Additionally during and after the processing (whether it is surgery, radiotherapy or chemotherapy) it is very significant to maintain the best possible nutritional status, since all these processing, in smaller or greater degree, originate a series of digestive alterations, as they can be: loss of appetite, nauseas, vomits, gases, diarrheas, estreñimiento, dry mouth and taste perversions and the olfato.
