After 20 years of research, a team of Mexican scientists has managed to cure 29 patients with HPV.
The human papillomavirus is a badually transmitted disease that is one of the leading causes of cervical cancer in women. Although this is the most common STD, there has been no cure for the infection – until now.
Scientists from the Polytechnic Institute of Mexico (IPN) have developed the treatment with the aid of a non-invasive procedure called photodynamic therapy. In addition to treating the virus, the researchers used the procedure to treat pre-cancerous cancer tumors that develop during the early stages of cervical cancer.
The treatment was given to patients who had been diagnosed with two strains of HPV commonly badociated with cancer, precancerous lesions, or both.
Lead researcher Eva Ramón Gallegos has spent more than two decades researching various applications of photodynamic therapy to find the most effective combination of chemicals to treat HPV and cervical cancer. uterus. For this particular test, she applied a drug called aminolevulinic delta acid to the cervix of the uterus.

After several hours, the drug enters the nucleus of nearby cancer cells and glows with a fluorescent glow so that scientists can track its progress. Once the drug is activated, researchers can activate it with the help of a special laser beam that allows the chemical to destroy the cancer cells.
More importantly, the treatment has virtually no side effects and leaves healthy cells unscathed.

During the first phase of the Gallegos trials, she tested the treatment of 420 women in Oaxaca and Veracruz. The therapy successfully cured 85% of women who had only HPV; 85% of women with HPV and lesions; and 45% of women with lesions, but no HPV.
During the second phase of the trial, they changed the frequency and dosage of treatment in 29 women in Mexico City. The alternative application eventually cured 100% of patients with HPV and no lesions; 64.3% of women with HPV and lesions; and 57.2% of women with lesions, but not with HPV.

IPN issued a press release on research results earlier this month in recognition of World Cancer Day, although Gallagos' previous research was published in the paper. Photochemistry and photobiology back in April 2017.
Although the researchers did not explain in detail how they had used this treatment to attack HPV strains, Chinese and Italian researchers shared the same success using photodynamic therapy to treat HPV.
