Cervical Cancer Progression and Staging
宫颈癌的进展与分期
The staging of cervical cancer refers to the extent of the disease. Doctors stage the disease according to the size of the tumor and whether it has spread to nearby tissues or other organs of the body.
宫颈癌分期指疾病的侵犯程度。医生根据肿瘤的大小，及其是否扩散到临近组织，或身体的其他器官分期疾病。
Stage 0 is not considered invasive because the cancer cells are found only in the top layer of cells of the cervix.
0期是非浸润性癌，因为癌细胞只存在于宫颈细胞的最上层。
Stage 1A is considered invasive cancer because the microscopic tumor grows through the top layer of cells into the underlying cervical tissue and is three to five millimeters deep by 7 millimeters wide.
1A期是浸润性癌，因为显微镜下，肿瘤自最上层细胞生长到下面的宫颈组织，浸润深度约 3-5 mm，宽度为7 mm。
Stage 1B cervical cancer has two scenarios. One, where the tumor still can only be seen with a microscope but is larger than five millimeters deep and seven millimeters wide. In the second scenario, for stage 1B the cancer can be seen without a microscope and is larger than 4 centimeters in diameter.
1B期宫颈癌分为两种情况。①显微镜下仍可见肿瘤，但浸润深度＞5 mm，宽度＞7mm。②1B期癌症无需显微镜也可看到，直径＞4 cm。
In stage 2A the tumor spreads beyond the cervix to the upper 2/3 of the vagina but not to the tissues around the uterus. In stage 2B the cancer spreads to the tissues around the uterus.
2A期，肿瘤从宫颈扩散到阴道的上2/3部分，但未扩散到子宫周围的组织。2B期，癌症扩散到子宫周围的组织。
In stage 3A the tumor spreads to the lower third of the vagina.
3A期，肿瘤扩散到阴道的下1/3部分。
In stage 3B, the cancer spreads to the pelvic wall, the lining of the body wall cavity between the hips, or it may spread to the ureters, tubes that carry urine away from the kidneys to the bladder. If the flow of urine is blocked, the kidneys can become enlarged or stop working.
3B期，癌细胞扩散到盆腔壁，即髋关节间的体腔内壁，或者扩散到输尿管--将尿液从肾脏传输到膀胱的管道。如果尿流受阻，肾脏会增大，或者停止发挥功能。
In stage 4A tumor invades nearby pelvic organs such as the bladder or rectum and may spread to the pelvic lymph nodes.
4A期，肿瘤侵犯邻近盆腔器官，如膀胱或直肠，并可能扩散到盆腔淋巴结。
In stage 4B, the cancer spreads past the pelvic lymph nodes to other places in the body, such as the liver, intestines, or lungs.
4B期，癌细胞通过盆腔淋巴结扩散到身体其他部位，如肝脏、肠道或肺。
