Mexican scientists can eliminate 100 human papillomaviruses


The condition, focused on the cervix of 29 women, was treated with photodynamic therapy, a noninvasive technique that may be an effective method to prevent neoplasia, which is the second leading cause of death in Mexicans.

In an interview with journalists, National Polytechnic Institute (IPN) scientist Eva Ramón Gallegos explained that the therapy, in addition to eradicating HPV, also eliminates pre-malignant lesions of cervical cancer at an early stage.

The researcher said that in the clinical phase this therapy has been treated with more patients in the states of Oaxaca and Veracruz, in addition to those residing in the Mexican capital,

The latter had pre-malignant lesions in the cervix or had both infections and those who eradicated the disease.

The treatment was performed in two stages, under different treatment schedules.

In the first part, which was attended by women from Oaxaca and Veracruz, the results were encouraging.

However, in the application of the technique to women in the capital also had a very encouraging effect, which opened the possibility of making the treatment more effective, using the scheme adapted to the situation of patients.

According to Ramón Gallegos, the therapy involves the application of a drug called delta aminolevulinic acid to the cervix, which after four hours turns into protoporphyrin IX, a fluorescent chemical that accumulates in damaged cells, allowing the elimination with a special laser beam, only structures impregnated with it.

Prior to administering photodynamic therapy to patients, colposcopy, cytology, hybrid capture, polymerase chain reaction and biopsy were performed to diagnose pre-malignant lesions and / or HPV infections.

At the end of the treatment, the same studies were repeated and the efficacy of said treatment was confirmed.

Ramón Gallegos commented that photodynamic therapy is safe and free of side effects.

"Unlike other treatments, it only eliminates damaged cells and does not affect healthy structures, which is why it has great potential to reduce the mortality rate from cervical cancer," he added.

According to the World Health Organization (WHO), this infection is transmitted sexually and is the leading cause of cervical cancer in women.


The scientific progress of the IPN represents a life expectancy for María González, because a decade ago she contracted HPV and only one year ago discovered that she is a carrier.

In an interview with Xinhua, González commented that he never noticed anything unusual in his body, not a mark, lump or any pain, so he did not perform medical check ups regularly.

However, in a health caravan that arrived in his hometown of Mexico City, he decided to have a Pap smear, and at that time he received the news that he contracted the infection and that he was at risk of having cervical cancer .

"I believe we Mexicans need to pay more attention to ourselves because we are so concerned about children, cleanliness or husband that we do not realize that we have to take care of the most valuable thing we have: our health," he said. .

Therefore, Maria said that this therapy (non-invasive) is an ideal option to eradicate HPV and eliminate the risk of cancer.

"This discovery will certainly help me and also millions of women in the world," he concluded.

María is the mother of two children, aged between 12 and 10 years, is housewife and wife of Carlos, who is also a carrier of HPV and is receiving treatment to fight it.

According to experts, cervical cancer tends to occur in middle age and is diagnosed more often in women between the ages of 35 and 44 years.

Many women do not realize that the risk of cervical cancer still exists as they get older; therefore, more than 15% of cases of cervical cancer are detected at an advanced stage.
