It found women with chlamydia serotype G had more than six times the risk of developing cervical cancer. Those with serotype I had four times the risk while those with serotype D had nearly three times the risk. Chlamydia is transmitted by a group of microorganisms of a size between bacteria and viruses, and can lead to various genital, eye and lymph node infections. Like a virus, it can only multiply after invading the body's cells. Among sexually transmitted infections, human papillomaviruses, or genital warts, are the leading cause of abnormal cell growth in the area around the cervix.
