Cervical cancer is a relatively common malignant tumor in women at this stage, and is divided into in situ and invasive cancers. Although cervical cancer is highly malignant, it is not a contagious disease, so cervical cancer itself is not contagious. However, human papilloma virus or HPV virus is one of the most important factors causing cervical cancer, and HPV virus is somewhat contagious. Cervical cancer is simply a malignant disease caused by a malignant tumor growing on top of the cervix. In the early stage, cervical cancer may not have any obvious symptoms because there are fewer blood vessels and nerves in the cervix, so you will not feel any pain or other suffering if the symptoms are not serious. However, cervical cancer may have a series of clinical symptoms such as contact bleeding, painless vaginal bleeding and bloody leucorrhea in early stage. Cervical cancer is common in women around 40-50 years old, because the estrogen in women’s body decreases during this period, so the incidence is higher than other times. Therefore, if women experience these symptoms, they need to go to the hospital for relevant examinations to rule out the possibility of cervical cancer. Although cervical cancer is not contagious, it has a certain degree of heredity. Women over 30 years old should be screened for cervical cancer once a year, as early screening for cervical cancer is very important to determine whether they have cervical cancer.
