for each person to hear a word from a doctor is tantamount to a death sentence.That is why many people avoid timely examination by experts because of fear to know about the terrible diagnosis.
Scientists say that the time was diagnosed with cancer in the early stages can be treated successfully.Consciousness of European citizens in matters of health is much higher than that of the Russians.
But the main issue of concern to human minds: "How to develop cancer?"Despite the incessant research physicians, the secret origin of the disease in humans is still undisclosed.Universal cure for cancer has not yet been invented.
history of cancer research
Since ancient times, humanity is concerned about an unknown disease that destroys the young and the elderly.About illness resembling symptoms of cancer, is mentioned in ancient Egyptian chronicles, whose age is 3000 years.This suggests that the disease is as old as humanity.The term "cancer" was introduced by Hippocrates, who oversaw the pathological process of breast cancer patients.He called the disease "onkos", which means "swelling".
Until the middle of the Middle Ages there was a ban on the dissection of bodies after death, and cancer research stopped.In the 17-18 th centuries, an era of Enlightenment.The doctors were given permission to study the causes of death of people by autopsy.At this time, the scientific study of cancer has leaped forward.They were found all kinds and stages of the disease, and humanity was horrified.The worst thing was that it was absolutely not clear, how to develop cancer?
Later, doctors have learned to distinguish between the tumor on the basis of the chances of survival of the sick person.They began to be divided into benign and malignant.The first distinguished by slow growth does not metastasize and safely removed by surgery.Malignant tumors are characterized by the fact that developed very quickly and killed the man through metastasis.This cell, which is separated from the parent tumor and blood or lymph spread throughout the human body, or move within the body cavities.They produce toxins and act oppressively on healthy cells.Consuming enormous amounts of glucose from the blood, they are deprived of food other cells and organs.Poisoned cancerous toxins the body is exhausted and dies.
How to start a cancer?
What would be the size of a tumor or reached, it originates from a single cell.As once the most common unit of an organism, it performed the usual function.But then something happened, and this is the steel cage to the body and foreign ceased to obey the laws of physiology.So far, it has not changed in appearance, agents of immunity did not touch her.But soon the cells began to multiply incessantly.For the newly formed substances need enormous amounts of energy.Her they draw from the blood stream.Therefore, the cancer has a highly developed system of blood vessels.Sucking the blood of all the sugar, the tumor stops growing and weaken the host.This is an exemplary mechanism of how to develop cancer.But why this happens is still a mystery.
Scientists have pinned great hopes on deciphering the human genome.They assumed that this code will be able to find the key to the question about the cause of cancer.But many hopes were in vain.Even disclosing the fact that a person's DNA has a predisposition to cancer, cure terrible disease at the genetic level, they can not yet.
Risk Factors
In a study of the question of how to develop cancer, scientists have left a lot of mysteries.But they failed to clearly define which factors can cause the formation of tumors.These causes have been called risk factors.These include:
- Carcinogens.Back in the 18th century British scientist Pott's discovery was made: chimney sweeps get cancer of the scrotum is much more often than other men.The reason for this - the constant contact with the soot.These substances also includes asbestos, tobacco smoke, 3,4-benzopyrene and some others.
- radiation.Sad examples of Hiroshima and Nagasaki, and Chernobyl, the scientists showed that ionizing radiation is a powerful impetus to the development of cancerous tumors.The incidence of people after irradiation increased forty-fold.
- viral infection.Infected by a virus cancer - is not a myth.It is proved that the human papilloma virus is able to provoke a woman developing cervical cancer.The infection can be transmitted sexually, and women often change partners, have a greater risk of developing cancer disease.
- Hereditary predisposition.In medicine, there is such a thing as "cancer family".But how do you know what is the likelihood of the child developing cancer?Indeed, if in the family there are some cancer patients, the probability of illness from this disease increases.But to be born in such a family does not mean for a man that he always sick and die from cancer.It is a predisposition that way may not show.
- Lifestyle rights.What a person eats, drinks, and how that relates to your body directly affects his health.Influence of bad habits, particularly smoking, the occurrence of cancer proved by years of research in this area.
Features cancer treatment
All the people know that the disease is easier to prevent than to treat.This applies in particular to cancer.The doctor can cure gastritis running, but in the case of the last stage of cancer, he is not likely to give a good prognosis.
Experts usually good cure cancer in its early stages.The technique selected purely individual.Surgery, radiation or chemotherapy - all of these methods are effective, but for the timely seeking help patients.After the treatment the doctors judged the effectiveness of the measures in terms of the five-year survival rate.If during this period of rehabilitation cancer not made itself felt, the doctors concluded that a person is healthy.
Let's analyze in more detail how you can get cancer.
Can you get cancer?
learning that a person has cancer, his entourage sometimes unwittingly tries to stay away from him.Doctors often hear their patients the question: "Can you get cancer?"Recent scientific research in this field has shown that there are viruses that contribute to cancer.These pathogens include:
- Hepatitis B and C. In most cases, they are transmitted sexually or through blood.Once in the body, affect the liver.Initiates an active cell division, there is inflammation and the risk of transformation of healthy tissue into cancer.
- Human Papilloma Virus.It is sexually transmitted and can cause cervical cancer.With increasing rates of partner change in women increases the risk of cancer.Vaccination against HPV is not capable of 100% to prevent the occurrence of cancer, also has a lot of contraindications.
- Herpes viruses, including Epstein-Barr virus.It manifests symptoms of angina and increases the risk of leukemia.
Can you get stomach cancer?
It is believed that the bacterium Helicobacter pylori can cause this serious illness.How can cancer of the stomach?Kissing sick or drinking from his cup?Do not panic.This bacterium itself is not a cause of cancer.If the gastric mucosa is damaged, this germ can cause ulceration.This pathology, in turn, can trigger the development of cancer.But ulcers caused by Helicobacter pylori, can be successfully treated with antibiotics.The risk of cancer provokes overweight, excessive consumption of red meat and other risk factors described earlier.
How to prevent cervical cancer?
Many women are interested in the question of how not to develop cancer of the cervix?Experts give a number of recommendations:
- Timely and regular visits to the gynecologist.The frequency of examinations of women at this specialist should be at least twice a year to conduct Pap test.In this mode it is possible to detect in time the appearance of tumors or other pathological changes in the reproductive system of women.This facilitates a timely response to the problem - carry out the necessary treatment - and eliminate the more serious problems in the future.
- suitable and reliable contraception.Proper planning will help children avoid abortion women.As the gynecological practice, two out of three women with cervical cancer have resorted to abortion.Each had an abortion increases the risk of cancer by 8%.
- Avoid casual sex and frequent partner change.If unprotected intercourse occurs transmission of the virus, which causes cervical cancer.
- vaccine against HPV.This measure is effective against 80% of the species of microorganism.
How does brain cancer?
Doctors can not clearly answer the question of how to develop cancer of the brain.Determine the causes of cancer of the body to science is not yet possible.However, doctors were able to become familiar with a group of factors that can cause the formation of brain tumors.These include:
- genetic component.Part of brain cancer is able to occur in people who have had similar illness in the family.Also, a number of syndromes may provoke cancer.These include neurofibromatosis first and second type, Gorlin syndrome and Turks.
- radiation or ionizing radiation.This factor is important for the workers of the nuclear industry.The risk also includes patients who had radiation therapy of the head as a treatment.
- Carcinogenic chemicals.People working in the plastics and textiles, are also at risk because of close contact with hazardous chemicals.
spores cause an impact on the brain injury, and mobile devices.Undefined is a direct relationship between them and the occurrence of brain cancer.Conversely, people with diagnosed oncology this body could never be exposed to these particular factors.
That can lead to cancer of the blood?
For many people, there is nothing worse as blood cancer.Today, this disease claims the lives of hundreds of thousands of people, and the cause of its occurrence is still a mystery to doctors.However, studies in this area have given clear information on a number of factors that can trigger leukemia.Among them are the following criteria:
- radiation.People exposed to the hazards have a big enough risk of various forms of leukemia: acute myeloid, chronic myelocytic or acute lymphoblastic.
- Tobacco smoking increases the risk of acute myeloblastic leukemia in form.
- Chemotherapy as a treatment for various forms of cancer can be an agent provocateur leukemia.
- innate nature of chromosomal disorders such as Down syndrome, increases the risk of leukemia.
- Heredity is rarely associated with the development of blood cancer.If this happens, then we are talking about lymphocytic leukemia.
But even if a person has been exposed to one or more factors, this does not mean that it will necessarily be ill with leukemia.The disease may not appear.
How does lung cancer?
On the dangers of smoking hear every person on the planet.However, smokers of this have not diminished.According to statistics, 90% of it is this is the main cause of a precipitating factor in the development of cancers of the respiratory system of the person.Heavy smokers and do not notice how ill with lung cancer.Tobacco smoke contains many carcinogens that with prolonged exposure to disrupt the structure of bronchial epithelium, columnar epithelium is transformed into a multi-layer flat, and there is lung cancer.At risk are also passive smokers.
to harmful factors that can cause lung cancer, also include:
- polluted air of large cities.
- chemicals carcinogens: chromium, arsenic, nickel and asbestos.
- Chronic inflammation of the respiratory system.
- Borne tuberculosis.
- Pulmonary fibrosis.
Any pathological changes are clearly visible on x-ray of the lungs.Therefore, each year should receive chest X-rays.
live without cancer
Practice shows that no one is safe from cancer.However, following some of the recommendations can significantly reduce the risk of this terrible disease.Doctors advise us how to live, not to cancer.Here are some simple recommendations to these:
- takbakokureniya Get rid of and reduce the risk of cancer by 10 times.
- blood test for viral infections.If a person is a carrier of a dangerous pathogen, it is necessary to regularly monitor the condition of their health.
- strengthens the immune system.A healthy lifestyle, proper rest, exercise classes feasible, bath treatments, tempering - all this strengthens the immune system and leaves no chance of cancer.
- pay enough attention to preventive examinations.It is necessary to regularly visit all the right people and take appropriate tests.Time to diagnose cancer is almost always curable.
- Avoid stress and negative thoughts.Optimists live longer and better.
Food against cancer
Experts also give us some recommendations how to eat to avoid getting cancer.There is a direct pattern between the composition of the diet and the risk of developing cancer disease.According to the WHO, 40% of cancers in men and 60% in women associated with errors in the diet.
anticancer diet has two main areas: food discourages carcinogens into the body and the use of natural onkoprotektor.Doctors give the following advice on diet:
- Limit consumption of smoked, as polycyclic hydrocarbons - is a strong carcinogen.
- Proper storage of products at sufficiently low temperature inhibits the development of them carcinogens.
- choose the right method of cooking - it is boiling, stewing and steaming.
- temperature control of food: it should not be too hot and cold.
- not abuse the salt.Daily rate - 5 g, and it is usually found in foods.
- Avoid overeating which leads to obesity and cancer.
- reduce the use of animal fats in favor of vegetable oils.
- Adequate intake of vitamins and minerals, such as E, A, C, D, B9, B2, B6, B5, potassium, selenium, iodine and reduces the risk of cancer.
- Eating fiber reduces the risk of the plant.In the daily diet must contain 5 servings of fresh vegetables, fruits, bran cereals, legumes.
Conclusion The nature of cancer has not yet been solved by modern medical science.This disease can occur in a person of absolutely healthy family, and, on the contrary, a person at risk for all parameters, can happily live to a ripe old age, not knowing about the oncological diseases.As long as humanity has not found an answer to the question of how people get cancer, and not invented by him medicine, we can minimize the risks and to live in harmony with their own body.Be healthy and not get sick!
