Cervical cancer is a kind of gynecological disease caused by malignant tumor in the cervix of women, which is also a relatively common malignant tumor at this stage. In early stage, cervical cancer bleeding is a small amount of bleeding, usually coffee-colored or black with foul odor, while in late stage, there is a large amount of bleeding, but the color of this bleeding is bright red with some flesh-like tissue. Because the nerves in the cervix are not rich, the lesions are often asymptomatic, and when there are symptoms, they are already at an advanced stage. This is especially true for cervical cancer. In the early stage of cervical cancer, women may have no other special symptoms, but only a small amount of vaginal bleeding after sex or strenuous exercise, which is coffee-colored or black in color and smells foul. With the development of the disease, the malignant tumor will become bigger and bigger, and the blood vessels inside the tumor are richly distributed, which will rupture after certain stimulation, thus causing a lot of bleeding, and the blood that comes out at this time is bright red, not black or brown. Therefore, whenever women find irregular vaginal bleeding, no matter what color it is, they need to actively go to the hospital for relevant examinations to rule out the possibility of cervical cancer. Cervical cancer screening is especially important.
