Cervical Cancer



What is cervical cancer?

This cancer is the development of malignant or cancerous cells in cervical tissue of women.

Anatomically, the uterus is a cavity where women have fertilized embryo develops, it is called the cervix or cervical canal that connects the uterus to the vagina, so this is the way for the baby to leave the womb to the outside at the time of birth, it is also known as "birth canal”.

The cervix, like any other organ, is made up of different types of cells and depending on the affected cells the type of cancer is determined.
Most cases, it is "squamous cell carcinomas, squamous cells”, that are found on the surface of the cervix. About 10% are "adenocarcinomas", originated in the cervical mucus.

Each year about 15,000 women are diagnosed with cervical cancer, in the U.S. only

Cervical cancer is one of the leading causes of death among women, mostly Americans, however, thanks to the Pap test, which detects abnormal cells in the cervix and allows the cancer discovery, the mortality from this case has been significantly reduced for the good of all women.

When cervical cancer is caught early it can be cured.

The odds of survival are favorable. Life expectancy for women diagnosed with cervical cancer early aggressive (aggressive means that the cancer has spread deeper into the cervix and / or other tissues or organs) is 70%, while for women diagnosed with noninvasive cancer (when only affected the surface of the cervix) is 100%.


Population at risk

Women can be found in greater susceptibility of developing cervical cancer are those who have in their lives the following factors:

  • Age 40 years or more
  • Have contracted HPV infections
  • Early active sexual age
  • Many sexual partners
  • Smoker
  • Low defenses or immune system low.
  • Family history of cancer (especially cervical cancer)
  • Being a consumer of birth control pills for a long period

HPV and Cervical Cancer

The main cause of cervical cancer is infection with HPV. HPV is the most common sexually transmitted disease today.

In most cases, the man can be the carrier of the disease without even knowing it.
Infection occurs from sexual contact of a healthy woman and a man carrying the virus that sow’s it in the lining of the cervix.

In most cases the defense systems, the agency responsible for removing the virus and the infection resolves it without sequels.
But the misfortune is that the HPV virus has mechanisms to attach to the epithelial cells and transform them into malignant cells.
The virus has a protein capsule that allows it to adhere to the epithelial cells of the cervix.

Cervical cancer begins to develop when the virus manages to insert its genes into the infected cell's genes so that the virus remains while the cell is alive.

The genes of the virus produce a type of protein that attacks the genes that are responsible for maintaining healthy the cell, that cell is transformed into a malignant cell that grows on its own and then attack other tissues.

This process takes a long period of time, usually about 10 years.


Treatment and Prevention

Cervical cancer is advancing rapidly worldwide.

If cervical cancer is detected early, it will be necessary to treat the patient with a combination treatment of chemotherapy and radiotherapy.

Fortunately, cervical cancer can be detected in time, with regular visits to the gynecologist and an annual Pap test. So the doctor can detect it and take steps to eliminate it.

The Pap test or Pap smear is a test that examines cells from the cervix with a microscope to detect abnormal changes in those cells.

Getting a Pap smear is an opportunity not to die of cancer of the cervix, allowing it to be detected and treated early.

The Pap test is a must in the life of every sexually active woman.

Developed vaccines against HPV cause the body to produce antibodies that act against the virus and thus prevent infection.

It is recommended that all women are vaccinated before sexual intercourse; it is recommended to vaccinate all girls aged 14 or older who are virgins.

The more sexual partners, the more likely you are to get HPV, so the vaccine is also recommended for women with many sexual partners.

Vaccination and regular visits to the gynecologist, may prevent most cases of cervical cancer.
