Cervical cancer stages and survival rates

Cancer is a very complex disease and the symptoms are different at each stage of cancer. Cervical cancer can usually be divided into several stages, and conservative treatment methods can be used to treat cervical cancer. Of course, the issue that people are most concerned about is the survival rate. Everyone hopes that the survival rate will be higher. Therefore, after cervical cancer occurs, it is important to understand the cause of the disease. What are the stages and survival rates of cervical cancer?

Stage 0: Carcinoma in situ. Stage I: The cancer is confined to the cervix. Stage IA: Invasive cancer that can be diagnosed only under a microscope. IA1: The depth of tumor microinvasion does not exceed 3 mm and the width does not exceed 7 mm; IA2: The depth of tumor microinvasion exceeds 3 mm but does not exceed 5 mm, and the width does not exceed 7 mm. Stage IB: The depth and breadth of tumor invasion exceed that of stage IA2, or the tumor is visible to the naked eye.

IB1: The tumor is smaller than 4 cm when visible to the naked eye; IB2: The tumor is larger than 4 cm when visible to the naked eye. Stage II: The tumor extends beyond the cervix but has not invaded the lower third of the vagina or the pelvic wall. IIA: no obvious parametrial invasion; IIB: obvious parametrial invasion. Stage III: The tumor invades the lower 1/3 of the vagina or the pelvic wall, or causes hydronephrosis. IIIA: The tumor invades the lower 1/3 of the vagina but does not invade the pelvic wall; IIIB: The tumor invades the pelvic wall or causes hydronephrosis. Stage IV: The tumor has invaded the bladder muscle or rectal muscle, or tissues outside the pelvis. IVA: The tumor invades the bladder muscle or rectal muscle; IVB: The tumor has distant metastasis.

The staging of cervical cancer is very complicated, and the staging of cervical cancer is often closely related to the patient's treatment method and prognosis. The following is an introduction to the prognosis of cervical cancer:

Relevant data show that after surgery or radiotherapy, the current five-year survival rate is 55.5%. Among them, the five-year survival rate of patients with stage IA cervical cancer can reach more than 95%. For stage IB cervical cancer, the five-year survival rate is 80 to 85%, for stage II it is 60 to 70%, and for stage III it is 30 to 35%. The prognosis for advanced cervical cancer is far worse than that for early and middle-stage disease, with a five-year survival rate of only about 14%.

The key to the treatment of cervical cancer is early detection and early treatment. The earlier the stage, the greater the hope of cure. It is recommended that you pay more attention to your physical changes and take prompt measures if you experience any discomfort.
