new YORK (Reuters Health) – a review of studies

published shows that persons with overweight and obesity

they are more likely to develop polyps of the colon, possible

precursors of cancer, people with normal weight

polyps, or adenomas, are a set of cells that

they grow on the wall of the colon. Although less than 10 percent is

cancerous, the majority of colon tumors arise from polyps.

previous studies had associated obesity with cancer

colon, a relationship that recognizes the National Institute of the

Cancer, but the review is the first study that points a

increase the risk of developing adenomas in the population with

overweight or obesity.

“given that referred to the relationship between obesity and the

cancer, would be logical to think of a connection between obesity and

a” Paso previo al cáncer, el adenoom”dijo el arts Hutan

Ashrafian, del Imperial College de Londres y coautor de la

revisión.

La Organización Mundial de la Salud (OMS) estima que en el

mundo hooi 500 http://bln.gs/b/1qdubd de personas obesas. Sus últimas cifras

omschrijven que nl el 2008 murieron más de medio millón de personas

por cáncer de dubbele punt een nivel mundial.

El equipo de Ashrafian analizó 23 estudios sobre un totale de

más de 100.000 habitantes de Estados Unidos, Europa Azië y para

om ketting van la relación entre los pólipos y el índice de masa

korporaal (IMC).

Todos los estudios cumplían con las guías de la OMS: las

personas con un IMC superieure een 25 tiene sobrepeso y con un IMC

superior een 30 zoon obesas. nl la mayoría de los estudios, los

pólipos se habían detectado con colonoscopías; dos estudios

habían used cuestionarios.

Los authors found that 22 percent of the

overweight and obese participants had polyps of the colon,

compared with 19 percent of people with weight normal.

the risk of developing polyps believed as he did so the

IMC.

“results suggest that obesity would influence (in the

appearance of cancer) long before than we thought”, said

Ashrafian.

in the study published in the American Journal of

Gastroenterology, the authors recommend to use the research

of colon cancer in people with overweight and obesity.

The Special Commission of the United States preventive services

(USPSTF, by its English name) recommends screening

between 50 and 75 years (there are several tests, including one

economic stool). in United Kingdom, research the

offers the national service of health between 60 and 69 years.

new study shows the need to orient the review

to obese population, according to felt Dr. Joseph Anderson, of

Dartmouth, Hanover, New Hampshire. added that there are different

tests and that obese people are a high risk group by

what to make them a colonoscopy full.

Anderson, who did not participate in the study, explained that the

obese people tend to develop adenomas in the part

superior of the colon that is inaccessible to the sigmoidoscopy.

but the doctor Michael Leitzman, University Hospital

of Regensburg, Germany, called for caution: BMI would not be

associated with more rapid cancer growth when they exist

polyps, so would be unnecessary to modify the search.
