Also, 99.7 percent of cervical tumors have their origin in persistent HPV infection
Mexico.- According to estimates, more than 80 percent of women are infected with human papillomavirus (HPV) during their active sex life, but only one percent develop cancer, says UNAM researcher Alejandro Garcia Carranca.
Also, 99.7 percent of cervical tumors have their origin in persistent HPV infection.
Garcia Carranca, leader of the "Laboratory for Virus and Cancer" group in the Biomedical Unit for Cancer Research at the National Autonomous University of Mexico (UNAM), said that recurrent HPV infections promote the development of cervical cancer. and that tumor progression can last 10 to 15 years.
In Mexico, cervical cancer is in second place in the incidence of morbidity due to malignant neoplasms in women, only after breast cancer and "there should not be such a high incidence," he added.
In a statement from the most study, the expert said that in the case of HPV the lesion is easy to detect and that it is relatively easy to treat them to avoid cervical cancer, there is also an effective vaccine.
Papiloma viruses have also been found in species such as fish, snakes, crocodiles, and birds, and they existed before humans appeared in which HPV infections on the skin and genital mucous membranes are very common.
Of the 200 species that exist, two thirds infect the skin and produce warts, and one third of the mucous membranes: oral, genital and anal; of which about 15 are considered high risk, such as types 16, 18, 31 or 33, because they are constantly found in tumors, but some with very low frequency.
He said that type 16 is the most common in almost all regions of the world (with the exception of East Africa, Japan and Taiwan) among women who have no cancer, but are the most common in tumors, up to 50 percent of them.
