Suppose that your cervix is an apple and that with a potato peeler you cut part of it. Well, more or less that way the conventional therapies to treat the Human Papilloma Virus (HPV) focused on the cervix that is applied in Mexico work.
Keeping in mind that these therapies lacked technological innovation, and that currently 79 million people are infected with some type of this virus worldwide, Dr. Eva Ramón Gallegos, of the National Polytechnic Institute (IPN), experimented and implemented a minimally invasive method, called photodynamic therapy, with which she managed to eradicate the HPV of 29 women from Mexico City.
HPV types 16 and 18 are responsible for 70 percent of all cases of cervical cancer (CoCu); the second cause of female death in Mexico, where one year there are between 4 thousand and 6 thousand cases and a day between 11 and 13 patients die.
Photodynamic therapy, explains the IPN researcher during his conference in Jalisco Talent Land 2019, is a medical technology that uses lasers to activate photosensitive drugs to treat cancer and other diseases through a non-surgical and minimally invasive means, "which are so invadable that it is as if you took the heart of an apple with a sharp device ".
This therapy consists of a drug known as delta-aminolevulinic acid in the cervix, which after four hours becomes Protoporphyrin IX, a fluorescent chemical that attaches to damaged cells. This allows, depending on the color and type of light with which the cells are excited, from making a diagnosis to eliminating with lasers rays the structures impregnated with that substance, which are the damaged cells.
