Cervical cancer It ranks second among cancer women. According to WHO annually registered more than 500 thousand new cases. Proved that a major role in causing the disease plays a human papilloma virus. Effective methods of treatment of infection does not exist, there is hope only in the body's natural defenses and vaccinated.
Human papillomavirus has manyspecies - strains, all of them in varying degrees dangerous to humans. Are considered the most aggressive 16,18, 31, 33, 48, 52 and 58 strains of the pathogen, they can be integrated into chromosomes of the cell and cause pathological changes. The greatest value against uterine cancer have a gang of 16 and 18 strainsFound in 80% of cases, during the examination of cases of women. Nizkoonkogennye types of the virus also rather offensive, cause growth and warts wartsWhich, though not degenerate into cancer, can deliver a lot of troubles to their owners.
Infection with human papilloma virus occurs during sexual intercourse, And it does not matter whether it was the contact withpenetration or oral sex. The causative agent is able to penetrate into the body, even when "innocent" contact of mucous. There are cases of infants infected during the passage through the genital tract of the patient's mother. Household methods of infection are extremely rare.
Infection - a disease does not mean!
The concepts of infection and disease are not equivalent. It is believed that almost everyone in the world during the life encounter with the human papillomavirus and only half of them sick. Most often, infection occurs at a young age and healthy, young immunity alone cope with the agent, in 80% of cases occur samoeliminatsiya virus. As the age of a chance at self-healing is reduced, most likely, this is connected with the peak incidence of cervical cancer in 45-year-old women.
About 20% of infected women papillomavirusIt remains in the body and causes the development of the disease. By embedding in the chromosomal apparatus of the cell, it changes it, which is reflected in the appearance of genital warts, cervical dysplasia and cancer. The process is not fast, it takes from 3 to 15 years, with no cases of self-healing excluded.
Because papilloma virus "instrument" in the surface cells of the cervix, the primary method of detection is study material taken from the cervix and cervical canal with its subsequent cytologyAs well as the identification of carriers of HPV.
It should be noted that the detection of oncogenichuman papilloma virus strains should not become a reason for the tragedy. In order to develop cancer, you need a large amount of the pathogen, so play the main role not qualitative and quantitative diagnostic methods.
When a carrier of human papilloma virus, and the absence of disease manifestations, must be monitored by a gynecologist: Seen 1 times a year, Check "smear on "Onkotsitologiyu" and analysis on the human papilloma virus. It is highly likely that at one point, the causative agent leaves the body permanently.
If any changes in the cervix carried out the necessary treatment: Cryosurgery, diathermocoagulation, removal of cervical lesion with a laser or radiowave knife, followed by the appointment of immunomodulatory drugs.
In identifying a woman carrier of human papilloma virus, a sexual partner treatment is not carried out, therapy is needed only in case of detection of warts.
One can go to talk about the need to limitthe number of sexual contacts, the need to use a condom, along with special means of protection against infections, sexually transmitted, but that little will change. The sexual revolution has done its job, and now everyone has a real chance to get the virus from their sexual partner without even involving the existence of he HPV infection.
The primary means of preventing HPV vaccine is now. Clinical trials of the vaccine ended in2005, it is still quite "young" scientists can not say with 100% certainty how safe their invention, so do vaccinations on a voluntary basis.
Vaccination against HPV shows girls 12-15 years. The vaccine provides protection against oncogenicstrains of human papilloma virus with a probability of 95-99%. And created immunity protects not only cervical cancer but also genital warts and warts. In order to create "a reliable shield" vaccination is carried out three times before the age of 20 years.
The vaccine against the human papilloma virus isthe product of genetic engineering, it does not contain the pathogen, so it is not capable of causing disease. However, if the body of HPV can activate it, so before vaccination is recommended to be tested for HPV.
