Another area of research in colon cancer prevention lies in the relationship between this disease and vitamin D. Researchers at the Catalan Institute of Oncology (ICO) has published a paper in the British Medical Journal, which has involved more than half a million people.

In the study, we analyzed vitamin D levels in blood and the number of people who developed colon cancer. The conclusions are clear: people with higher levels of vitamin D showed a 40% lower risk of colon cancer.

LACK OF VITAMIN D AND METASTASIS

Autonomous University of Madrid, has found a possible link between vitamin D and tumor development. A paper published in the Journal of Cell Biology explains that vitamin D may help prevent cancer in two ways.First, is activating genes that encode the E-cadherins, proteins involved in cell junctions and are linked to tumor development because its absence facilitates cell migration. This fact leads to an increase in the number of metastases (reproduction or extension of tumor to another part of the body). Secondly, vitamin D inhibits several proteins involved in the activation of the cytoskeleton, a set of polymers required for cell division and migration of metastasis. If it crashes the cytoskeleton of cancer cells, prevents these can be split and moved.

Researchers from John Hopkins University (USA) has discovered a bacterium that could be implicated in the development of colon cancer. The study is published in the journal Nature Medicine.

Scientists say that “Bacteroides fragilis, which can cause gastroenteritis, and boxes that are located in the intestines of children and adults around the world, is also responsible for some cases of this tumor.Higher levels of vitamin D in blood are associated with a lower risk of colon cancer

For the study, the bacteria were infected with various mutant mice a gene called APC, which is related to tumor development. Within a short time, animals had diarrhea and inflammation of the colon. In one week, the diarrhea disappeared but the swelling persisted and formed small tumors. A month later, the mice had developed cancer.

On the other hand, another group was treated mouse with a nontoxic strain of the same bacteria and the result was that the mice did not develop diarrhea or no tumors. The authors believe that the bacterium causes an inflammation of low level but persistent in the digestive tract. Thus, over time, the genetic material in epithelial cells may be damaged and cause tumor development.

13,101 people in 2006 died from colorectal cancer, a figure representing 12.9% of total cancer deaths during that year. This is one of the main conclusions of a study published in the journal European Journal of Cancer Prevention’.

The research analyzes the causes of these inequalities and seek a possible relationship to changes in diet (red meat, fish, vegetables) in the alcohol and snuff, and the exercise or sedentary. The good news is that the incidence of these tumors can be reduced. Just keep a healthy lifestyle.

Delete snuff, moderate alcohol, eating a balanced diet and avoid a sedentary lifestyle are some of the basic pillars of prevention.Alcohol and snuff primarily responsible

Among those responsible for the increase in these tumors emphasizes the consumption of snuff and alcohol. There is scientific evidence about the relationship between smoking and increased risk of developing colorectal polyps and cancer: from 12% to 21% of colorectal cancers could be attributable to smoking. “In Spain, consumption of cigarettes has increased apparent until the late eighties, with a stabilization from the late nineties” notes the study’s lead author and researcher at the University of Sevilla, Luis Maria Bejar.

Alcohol consumption also grew until the early eighties, followed later by a slow decline. Dietary habits with high consumption of red meat at the expense of a diet rich in vegetables and physical inactivity are other factors involved that stress specialists.

Green tea has gained the reputation it has in the world, largely due to the polyphenols, the substance that contains many of its properties. With these, commonly known as catechins, green tea can be considered one of the great man’s natural allies.Basically, the green tea polyphenol-type has four catechins: the epicatechin, epicatechin gallate, epigallocatechin and the epigallocatechin gallate.

These catechins are highly valued in the consumption of tea as they are the substances that have anticancer and antioxidant, especially those concerning the epigallocatechin-gallate, the major polyphenol present in green tea. Already there are several animal studies have clearly demonstrated that green tea can act brilliantly in preventing various cancers.

Among the studies which confirm the use of green tea for its good properties, the Doctor is Jankunas, who has indicated that the polyphenol epigallocatechin gallate can inhibit the enzyme urokinase, high in cancer patients. Japanese Sadzuka also indicated that green tea is good to eat during chemotherapy treatments.

Finally, some studies in the National Cancer Institute of USA and also in the China Cancer Institute revealed that in 902 Chinese patients with oesophageal cancer and 1552 patients without cancer, found that non-smoking male patients took at least a cup of tea a week had 57 percent lower risk female patients and 60 percent lower risk of developing esophageal cancer than those who did not drink tea during the same period. Learn how citrus fruits are enhancers of green tea antioxidants and how green tea could be the reason for the low rates of cancer in Asia.

Consequently believes that in addition to a preventive diet vegetarian diet should be basic in any department of oncology. After the very large number of studies performed, it appears that only vegetarians with cancer, which demonstrates their importance as primary prevention.

the important thing is its role as secondary prevention, if you have already had cancer, and as a tertiary prevention when they have occurred stages of metastasis.
Not forget that: “The low-calorie diets prolong life and improve the system
