After 20 years of research, a team of scientists from Mexico has succeeded in curing 29 patients of HPV. Human papillomavirus is a sexually-transmitted disease that is one of the main causes of cervical cancer in women. Though it is the most common STD, there has been no cure for the infection – until now.
Scientists from the Mexico Polytechnic Institute (IPN) developed the treatment using a non-invasive procedure called photodynamic therapy. In addition to treating the virus, the researchers used the procedure to treat premalignant cancer tumors during the early stages of cervical cancer.
The treatment was delivered to female patients who had either been diagnosed with two HPV strains commonly associated with cancer , premalignant lesions, or both
The lead researcher behind the treatment, Eva Ramón Gallegos, has spent two decades researching various applications of photodynamic therapy in order to find the most effective combination of chemicals to treat HPV and cervical cancer.

] After several hours, the drug makes its way into the nucleus of nearby cancer cells and shines with a bright fluorescent glow that scientists can track its progress. Once the drug is activated, researchers can activate the drug with a special laser beam that causes the chemical to destroy the cancer cells.
More importantly, the treatment has virtually no side effects and it leaves healthy cells unharmed. InvestigaciónIPN Eliminan ciento virus del papiloma humano. And Marco del Día Mundial Contra el Cáncer 201

During the first phase of Gallegos's trials, she tested the treatment on 420 women from 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 the treatment on 29 women from Mexico City. The alternative application ended up curing 100% of the patients with HPV and no lesions; 64.3% of the women with HPV and lesions; and 57.2% of women with lesions but no HPV.
