A powerful tool in medicine
prevention of cancer: antioxidants

Cancer is a set of diseases that is characterized by the abnormal proliferation of cells that divide without control and have a high ability to attack organs and tissues, and spread through the blood and lymphatic system. Malignancy is one of the primary driver of horribleness and mortality all through the world..

This alarming situation emphasizes the need for urgent prevention measures to win the battle against malignant growth these procedures ought to be founded on better proof, in light of the learning of the factors capable of increasing or decreasing the risk of this disease. Oxidizing stress is a condition that manifests itself in the body when the production of highly reactive substances exceeds the mechanisms antioxidants; This situation is responsible for the appearance of diseases. It has been discovered that consumption of food with beta-carotene protects against damage caused by X-rays; moreover, that the utilization of Foods with nutrient C and beta-carotene decline the risk of developing some types of cancers.

The evidence of oxidative stress participation in carcinogenesis and its deactivation by antioxidants have driven studies under the hypothesis that different antioxidants can be administered as supplements for the prevention of various types of cancer. Among the evaluated antioxidants are antioxidant vitamins A, E and C, coenzyme Q10, flavonoids, carotenoids and carotenoids.


Cancer, antioxidants, carotenoids, flavonoids, vitamins.

Through proper nutrition, man can have a decisive influence on your health, ability to perform and hope for lifetime. The human being, like all living beings, needs materials with which to build or repair your own organism, energy to make it work and regulators that control that process. To get them, you must provide your body with the required substances, which is made possible by feeding. It is defined as the feeding of sets of actions that allow introducing into human organisms the Food and sources of the raw materials you need must be obtained to carry out their functions vital.

Food includes several stages: selection, preparation and ingestion of food, voluntary processes. Nutrition, on the other hand, is the set of involuntary processes by which the body incorporates, transforms and uses the nutrients supplied with food, to perform its functions vital. Nutrition includes the digestion of food known as absorption and metabolism the assimilated nutrients and excretion of human waste not absorbed and those resulting from the metabolism of the cells.

For food to be considered healthy, it must be sufficient, complete, balanced and safe (SCEI). It is considered sufficient the food that provides the quantities optimal energy and essential nutrients for life. That is to say that proteins, fats, carbohydrates, vitamins, minerals and water, as well as the amount of dietary fiber are necessary for a correct intestinal function. The energy and nutrient needs vary for each individual, according to their characteristics and particular circumstances.

Symptoms of stomach cancer

Early-stage stomach cancer rarely causes symptoms, so stomach cancer is so difficult to detect early. The signs and symptoms of cancer in the stomach may include

  • Little appetite
  • Weight loss without trying to lose weight
  • Abdominal pain
  • Inaccurate discomfort in the abdomen, usually just above the navel
  • Feeling of fullness in the upper abdomen after eating a light meal
  • Heartburn heartburn or indigestion
  • sickness
  • Vomiting, with or without blood
  • Swelling or accumulation of fluid in the abdomen
  • Blood in the stool
  • Low red blood cell count anemia

Most of these symptoms are more likely to be caused by other conditions that are not cancer, such as a virus or a stomach ulcer. These also occur with other types of cancer. However, people with any of these problems, especially if they do not go away or get worse, should talk to their doctors to find and treat the cause.

Because the symptoms of stomach cancer often do not appear until the disease progresses, only one in 5 stomach cancers in the United States is at an early stage, it all depends on the time you are given because if you walk in all areas of the body.

Meaning of malignant growth

Malignant growth is a gathering of illnesses portrayed by the unusual expansion of cells that isolate wildly and have a high ability to attack organs and tissues, to spread through the blood and lymphatic framework. Harmful development is one of the essential driver of terribleness and mortality all through the world; is to point out that only 1-2% of neoplasms are an aftereffect of the legacy of inclining qualities, and the remaining 98-99% is auxiliary to natural cancer-causing agents; This is critical, since, in principle, most malignancy cases could or could be preventable.

At that point, in the improvement of malignancy, epigenetic factors, ecological qualities and way of life impact; among them are the dietary variables, which are related with 35% of disease passings in created nations and 20% in creating nations, since, for instance, high caloric thickness, liquor, creature fat and high glycemic list are identified with colon, bosom and prostate malignant growth.

The worldwide weight of malignant growth was evaluated at 14 a huge number of new cases in the year 2012, and He anticipates that this figure should increment to 22 million every year in the following two decades. Two of the most widely recognized diseases analyzed so far are the lung, bosom and internal organ. This aggravating condition emphasizes the prerequisite for basic balancing activity measures to win the battle against malignant growth; These techniques ought to be founded on better proof dependent on learning of the components equipped for expanding or diminishing the danger of this ailment.

The main source of free radicals are the mitochondria, lysosomes, peroxisomes, as well as the nuclear, cytoplasmic and of the endoplasmic reticulum. Free radicals They are also generated by factors such as environmental pollution, exposure to ionizing radiation, tobacco, medicines, chemical additives in processed foods and some xenobiotics such as pesticides, herbicides and fungicides. Under normal physiological conditions, the organism neutralizes the species Reactive Oxygen (ERO) through several cell reinforcement instruments that include the generation of cancer prevention agent chemicals, for example, (superoxide) (dismutase) (catalase) (glutathione) (peroxidase) and others, to prevent oxidant damage.

Vitamin E as an antioxidant and anticancer

The reactivity of vitamin E with peroxyl organic radicals is associated with the redox properties of the chroman ring and is responsible for its antioxidant capacity. The vitamin works in vivo as an antioxidant that protects tissue lipids from attack by free radicals. The peroxyl radicals (LOO0) can be generated, for example, from the polyunsaturated fatty acids of phospholipids of the membranes or in lipoproteins after the loss of hydrogens (process called "initiation") and the addition of a molecule of oxygen. Studies describe a lower concentration of vitamin E in the blood of patients against the mutagenesis induced by chemotherapy.

Family factors: A patient with a few relatives with gastric malignant growth has among 2 and 3 times more risk of suffering from it.


To date, there is not enough scientific evidence to recommend endoscopic screening in the healthy population of Western countries, where gastric cancer is not very frequent. Among the strategies to prevent the occurrence of stomach cancer SEOM insists on the importance of

Devour loads of new vegetables and organic products

An eating routine wealthy in leafy foods can help keep the beginning of stomach malignancy. More than 95 percent of stomach malignancies are adenocarcinomas, a sort of tumor that emerges from the uncontrolled development of the cells of the mucous organs. Inside the adenocarcinoma there are 2 intestinal and diffuse subtypes. Also, a typical kind of gastric malignant growth are sarcomas, melanomas, lymphomas, and gastrointestinal stromal tumors.


In Japan stomach malignant growth is exceptionally normal, gastroscopy tests are performed to get an early determination. In any case, as you state from the SEOM, so far in Western nations, it has not been demonstrated that the investigations that are normally performed in individuals however asymptomatic increment the survival of gastric malignant growth in these nations.

There is a more prominent provability that an individual with a few relatives with gastric malignant growth has somewhere in the range of 2 and multiple times more danger of likewise experiencing it.
