Genital herpes is usually considered to be a simple STD and a very scary one, mainly because it is very contagious and can easily recur with improper treatment, but recent information shows that genital herpes is very carcinogenic. Genital herpes can lead to a number of complications and has a high chance of causing cancer, which can have unimaginable consequences. How carcinogenic is genital herpes? What kind of cancer can genital herpes cause? Genital herpes is very carcinogenic, mainly because it is caused by a virus, and as early as the 1960s, it was suggested that the genital herpes virus could be a potentially important cancer-causing factor for cervical cancer. At the same time, herpes simplex virus-like particles were observed in biopsies from patients with penile cancer. However, direct evidence that herpes simplex virus is a causative agent of genital malignancies is still insufficient and needs to be further confirmed. In recent years, it has been clinically discovered that cervical cancer is associated with sexual activity, that genital herpes virus is a common causative factor in sexually active people, that the cervix is often the site of viral replication, and that genital herpes is often found to coexist with cervical cancer. Women who have had genital herpes are ten times more likely to have cervical cancer than those who have not had it. At the same time, recent scientific studies by relevant organizations have found genital herpes virus-specific antigens in cervical cancer tissue, exfoliated cells or pre-cancerous cells. Thus indicating that genital herpes virus plays an important role in the development of cervical cancer. Therefore, men and women are reminded that they must take precautions against such diseases, and if they suffer from genital herpes, they must be treated thoroughly, otherwise it will be very harmful to people, and patients must not let down their guard and step up treatment to avoid cancer.
