What The Meaning of Cancer
Perhaps one of the most frequently used words and the most frightening when talking about health and disease of cancer. This report aims to explain basic concepts to understand what this group of diseases and the more knowledgeable, the most common type of cancer in our society.
Want to prevent the cancer
Although the causes of cancer is not known in many cases, and multiply factor, it is known about risk factors that increase the likelihood of cancer and should be avoided, methods such as smoking or smoking. Already have the vaccine approved recently against cervical cancer, which affects and kills hundreds of women around the world. Marketing of this vaccine has been approved in several countries, and adoption studies of vaccines against other skin cancer and prostate cancer.
Cancer prognosis
In fact, the prognosis of patients may change from time to time. Live shows the percentage of people with certain types of cancer and stage of the disease survive for a certain period after their diagnosis. Many factors of affect prognosis; including the type, location and stage diseases, patient age, overall health and response for treatment.
But there are big differences between the sexes and between more and less developed countries, which is a reflection of the various risk factors were dominant in both areas (eating habits and sexual infections …)
The most common cancer in women (in order) on the breast, cervix, colorectal and lung. Men in the lung, prostate, stomach and colorectal.
Number of cases increased slowly in the world, for two main reasons: increasing world population and increasing life expectancy, which involved aging. But you can not underestimate the significant increase in exposure to risk factors.
Probiotics and Cancer
Cancer is usually caused by a mutation or abnormal activation genes that control cell growth and division. Most of the abnormal cells do not cause cancer because the cells usually exceed the normal abnormal. Also, the immune system recognize and destroy cells are abnormal.
Many processes can increase the exposure or the occurrence of abnormal cells. Precautions to minimize exposure of this lower risk of cancer. Among the many potential risk exposure of chemical exposure. Chemicals do cause cancer (carcinogens) may be delayed or the metabolic activity of microbes living in the gastrointestinal system.
Has been assumed that probiotic cultures may reduce exposure to chemical carcinogens:
(1) detoxification of carcinogens ingested
(2) change the environment of the gut Microbial population will reduce the metabolic activity of bacteria that can produce carcinogenic compounds
(3) produce metabolic products (butyrate) which improve the ability to die when delula must die (a process known as apoptosis or programmed cell death)
(4) produce compounds that inhibit the growth of tumor cells in
(5) stimulate the immune system to defend against the proliferation of cancer cells.
Research shows that consumption of probiotic supplements can reduce cancer risk. Researchers tested the effects of consumption or fermented foods have been found:
* A reduction in the incidence of chemical induced Tumors in mice.
* A reduction of fecal enzymes (glucuronidase, azoreductase, nitroreductase, and dehydrogenase 7) believe that the May play a role in colon cancer in humans and animals.
* Degradation of nitrosamines.
* A weak mutagenic activity of substances tested in the laboratory.
* Prevention of damage to DNA in certain colonic cells.
* Improve the function of the immune system.
Taken together, these results show that probiotic supplements can positively influence the gastrointestinal environment to reduce the risk of cancer. However, the reduction of cancer must be demonstrated in humans to confirm the importance of this observation.
