Papillomaviruses are a fairly common genus of viruses that often attack humans. There are over 100 varieties of this virus living in us. Some representatives of this genus are safe for humans, but there are those whose presence in our body provokes the appearance of benign and malignant tumors. Currently, it is no longer in doubt that the human papillomavirus is directly related to cervical cancer. Warts and papillomas are certainly contagious because they are caused by viruses called human papillomavirus (HPV). They differ in shape - oblong, conical, spherical, on legs, with a wide base. Papillomas can be keratinized, or they can melt into the color of the skin or mucous membrane on which they are located.
