Most inhabitants remains of the opinion that there is no illness worse than cancer.Any doctor is ready to challenge this idea, but a thing conservative public opinion.
And despite the fact that onco-pathology takes the third place among the causes of disability and death, people will be a very long time to believe that there is no worse than the disease, and to seek ways to prevent cancer.
known that any disease profilaktirovat cheaper and easier than cure, and cancer are no exception.The very treatment started at times more effective in the early stage of the disease than in advanced cases.
basic postulates that will not die of cancer:
- Reducing the impact on the body of carcinogens.Anyone removing from your life, at least part of oncogenic factors able to reduce the risk of cancer disease for at least 3 times.
- catch phrase - "all diseases of the nerves" for cancer is no exception.Stress is a trigger active growth of cancer cells.So avoid nervous shock, learn to deal with stress - meditation,
- Early diagnosis and early treatment.Modern Oncology finds that cancer detected at an early stage, curable in more than 90% of cases.
mechanism of tumor development
cancer in its development passes through three stages:
origin of cell mutations - initiation
constantly share in the process of life of our tissue cells, replacing lost or spent.In the fission can occur genetic errors (mutations) "cellular marriage."The mutation leads to permanent changes in cell genes influencing its DNA.These cells do not become normal, and begin to divide uncontrollably (in the presence of predisposing factors) to form a cancerous tumor.The reasons are the following mutations:
- Internal: genetic abnormalities, hormonal disruptions, etc.
- Exterior: radiation, smoking, heavy metals, etc.
World Health Organization (WHO) estimates that 90% of oncological diseases occur due to external causes.Factors external or internal environment, the impact of which can cause cancer and contribute to the growth of the tumor called - carcinogens.All
nucleation stage such cells may take several minutes - the time of carcinogen absorption in blood, its delivery to the cells attach to the DNA and a transition to the active compound.The process is completed when there is a formation of new daughter cells with altered genetic structure - everything!
And it is irreversible (with rare exceptions), see. Cell mutations occur 20 years before lung cancer.But this process can be suspended for as long as create favorable conditions for the further growth of colonies of cancer cells, as the immune system does not sleep, and struggling with such mutated cells.That is, with the weakening of immunity - a powerful stress (most often it is the loss of loved ones), severe infectious disease, as well as hormonal failure after injury (see link trauma and oncology.), Etc. -. The body can not cope with their growththen stage 2 begins.
presence of favorable conditions for the growth of mutating cells - Promotion
This is a much longer period (years, even decades) when newly emerged mutated cells predisposed to cancer, ready to multiply up to an appreciable cancer.That's right, this step may be reversible, because it all depends on whether the cancer cells are provided with the necessary conditions for growth.There are many different versions and theories of the causes of cancer, among them - the link growth of mutated cells and human nutrition.
For example, the authors T. Campbell, K. Campbell, in his book "The China Study, the results of a large-scale study on the relationship of nutrition and health", report the results of 35 years of research communication Oncology and the prevalence of protein foods in the diet.They argue that the presence promotes intensive growth of cancer cells, and vice versa, the presence in the diet antistimulyatorov (plant foods without heat, cooking) in the daily ration of more than 20% of animal protein (meat, fish, poultry, eggs, dairy products), slow down andeven stops their growth.
According to this theory, one should be very careful with a variety of fashionable today protein diets.Power must be complete, with an abundance of fruits and vegetables.If the person with cancer stage 0-1 (without knowing it) "sits" on the protein diet (for example, with the aim to lose weight), it essentially feeds cancer cells.
Development and growth - progression
third stage - the progressive growth of the group formed cancer cells, the conquest of neighboring and distant tissues, ie the development of metastases.This process is irreversible, but it is also possible to slow.
WHO separates carcinogens into 3 major groups:
- Physical Chemical Biological
science knows thousands of physical, chemical and biological factors that can cause cell mutations.However, carcinogens can be considered only by those whose action is significantly associated with the occurrence of tumors.This certainty must be provided by clinical, epidemiological and other research.Therefore, there is the concept of "potential carcinogen" is a factor, the effect of which could theoretically increase the risk of developing cancer, but its role has not been studied or proven in carcinogenesis.
This group of carcinogens are mainly different kinds of radiation.
The fact that radiation can cause genetic mutations, scientists have long known (Nobel Prize 1946, Joseph Muller), but strong evidence of the role of radiation in the development of tumors were obtained after studying the victims of the nuclear bombings of Hiroshima and Nagasaki.
main sources of ionizing radiation for the modern man following.
- Natural background radiation - 75%
- medical procedures - 20%
- Other - 5%.Among other things appear radionuclides trapped in the environment as a result of land-based nuclear weapons tests in the middle of the XX century, and got it in after the man-made disasters in Chernobyl and Fukushima.
influence the natural radioactive background is useless.Modern science does not know whether the people live entirely without radiation.So do not trust people who are advised to reduce the concentration of radon in the home (50% of the natural background), or to protect themselves from cosmic rays.
another matter X-ray examinations carried out for medical purposes.
In the USSR, chest X-rays of light (for tuberculosis), it was necessary to carry out 1 time in 3 years.This examination is required to pass each year in most of the CIS countries.This measure has reduced the spread of tuberculosis, but it affected the overall cancer incidence?The answer probably is not, because this issue no one did.
also very popular among the inhabitants computed tomography.At the urging of her patient who needs to do and do not need.However, most people forget that the CT is also x-ray, but more technological.Radiation dose in CT exceeds the usual X-ray of a 5 - 10 times (. cm CT in childhood increases the risk of cancer in the future).We are in any case does not call to abandon the X-ray studies.Just come to their destination must be very carefully.
However, there is still a force majeure, such as:
- lives on the premises, built of fonyaschih materials or they trimmed
- life under high-voltage lines
- service on submarines
- work radiologist, etc.
believed that the fashion for a tan introduced in the mid-twentieth century, Coco Chanel.However, in the XIX century, scientists knew that the constant exposure to sunlight ages the skin.Not just because the villagers look older than their urban peers.They no longer are in the sun.
UV light causes skin cancer, it is a proven fact (WHO 1994 Report).But particularly dangerous artificial UV - solarium.In 2003, WHO published a report on the fears associated with tanning beds and irresponsibility manufacturers of these devices.Tanning is prohibited to persons under 18 years in Germany, France, Great Britain, Belgium, the USA, and in Australia and Brazil, they are banned completely.So that bronze tan is probably nice, but not helpful.
Chronic skin trauma and mucous membranes can cause the development of tumors.Poor quality dentures can cause mouth cancer, and the constant friction of clothing on the birthmark - melanoma.Not every mole becomes cancer.But if she is in an elevated traumatic zone (around the neck - the friction collar on the face of men - the trauma shaving, etc.) should consider removing it.
irritation can also be thermally and chemically.Fans of very hot food put themselves at risk of oral cancer, throat and esophagus.Irritant effect has alcohol, so people prefer strong strong drinks, alcohol and the risk of gastric cancer.
Domestic electromagnetic radiation
We are talking about cell phone radiation, microwave ovens and Wi-Fi routers.
WHO officially carried cell phones to potential carcinogens.Information on the carcinogenicity of RF only theoretical, and on the impact of Wi-Fi in tumor growth data does not exist.On the contrary, studies demonstrating the safety of these devices more than fabrications about their dangers.
International Agency for Research on Cancer (IARC) separates the materials used in the home and at work, in their carcinogenicity in the following groups (information is provided as of 2004):
- reliably carcinogenic - 82 substances.Chemical agents carcinogenicity is not in doubt.
- probably carcinogenic - 65 substances.Chemical agents carcinogenicity which has a very high degree of evidence.
possible carcinogenic - 255 substances.Chemical agents which can be carcinogenic, but is questioned.
- probably non-carcinogenic - 475 substances.There is no evidence of carcinogenicity of these substances.
- authentically non-carcinogenic - chemical agents, proved not cause cancer.While in this group only one compound - caprolactam.
discuss the most important chemicals causing cancer.
Polycyclic aromatic hydrocarbons (PAHs)
This is a large group of chemicals formed during the incomplete combustion of organic products.Contained in cigarette smoke and car exhaust gas of thermal power plants, and other furnace carbon black formed during frying and thermal treatment of food oils.
Nitrates, nitrites, nitroso compounds
It is a by-product of modern agricultural chemistry.Nitrates themselves are harmless, but themselves over time, and as a result of metabolism in the human body, they can be converted to nitroso compound, which in turn are highly carcinogenic.
This chlorine-containing compounds, which are waste chemical and oil refining industries.May be part of transformer oils, pesticides and herbicides.May appear when burning household waste, especially plastic bottles or plastic packaging.Dioxins are extremely resistant to fracture, may therefore accumulate in the environment and the human body, especially the "love" Dioxins fatty tissue.Minimize hit dioksidina food is possible if:
- not freeze food, water in plastic bottles - so toxins can easily penetrate into the water and food
- not heat foods in plastic containers in the microwave, it is better to use tempered glass or ceramic containers
- Do not cover the food with plastic wrap on heating in a microwave oven, the best cover with a paper towel.
Metals with a density greater than that of iron.In the periodic table of about 40, but for a man most dangerous mercury, cadmium, lead, arsenic.In the environment these substances come from a waste of mining, steel, and chemical industries, a certain amount of heavy metals contained in tobacco smoke and car exhaust.
This is the common name of a group of fine-fiber materials containing basically silicates.By itself, asbestos is perfectly safe, but its tiny fibers into the air, call inadequate reaction of the epithelium, with whom they are in contact, become a cause of cancer of any organ, but most often causes lung cancer and larynx.
Case study local therapist : in a house built of asbestos exported from the territory of East Germany (the rejected in this country) statistics of cancer 3 times higher than in other houses.On this particular "fonyaschego" said the foreman of the construction material, which has worked in the construction of the house (she died of breast cancer after the operated already sarcoma toe).
According to research scientists, alcohol direct carcinogenic effect is not.However, it can act as a stimulus for chronic chemical epithelium of the mouth, throat, esophagus and stomach, promoting the development of tumors in them.Especially dangerous spirits (over 40 degrees).Therefore, I like to drink alcohol run the risk not only cirrhosis.
Some ways to avoid the influence of chemical carcinogens
Oncogenic chemicals can affect our bodies in many ways:
carcinogens in drinking water
According to Rospotrebnadzor data up to 30% natural waters contain exorbitant concentration of substances dangerous to humans.Also do not forget about intestinal diseases: cholera, dysentery, hepatitis A, etc. Therefore, water from natural reservoirs is better not to drink even boiled..
old, worn-out water supply system (of which in the CIS up to 70%) can cause contact with drinking water carcinogens from the soil, namely nitrates, heavy metals, pesticides, dioxins, etc. The best way to protection from them -. Use household system water purificationas well as to monitor the timely replacement of filters in these devices.
Water from natural sources (wells, springs, etc.) can not be considered safe, since the soil through which it runs can be anything - from pesticides and nitrates, to radioactive isotopes and chemical warfare agents.
Carcinogens in the air
main oncogenic factors in the inhaled air is tobacco smoke, car exhaust, and asbestos fibers.To breathe carcinogens need:
- Stop smoking and avoid secondhand smoke.
- City residents should at least go to the street on a hot, windless day.
- Avoid the use of building materials containing asbestos.
Carcinogens in food
Polycyclic hydrocarbons appear in meat and fish with significant overheating, that is, when frying, especially fat.Reusing cooking oils greatly increase the PAH content in them, so deep fryers for household and industrial - an excellent source of carcinogens.Dangerous not only potato fries, fried pies belyashi or bought in a stall in the street, but also barbecue, cooked with his own hands (see. Acrylamide in French fries, bread, coffee).
About shashlik worth special mention.The meat for this dish is cooked on hot coals, when there is no smoke, so it PAHs do not accumulate.The main thing - make sure that the barbecue is not burn and do not use the grill means of ignition, especially containing diesel fuel.
- Large amounts of PAH in food appear during smoking.
