However, an important distinction must be made between a dramatic headline and an established medical explanation. The image alone cannot verify the woman's diagnosis, medical history, or the cause of her illness. More importantly, ordinary underwear-washing habits are not an established direct cause of cervical cancer.
Cervical cancer develops in the cells of the cervix, the lower part of the uterus that connects to the vagina. Most cases are associated with persistent infection by high-risk types of HPV, a very common virus that can spread through intimate skin-to-skin contact.
Most HPV infections clear naturally. In some cases, however, a high-risk infection persists and causes cellular changes that may eventually develop into cancer over many years. This process is not the same as simply wearing or washing underwear incorrectly.
