Bile Duct Cancer Periods



Period I



Stage II



The very first period of cancer is Period 0, or carcinoma in-situ, which will be cancer that is non invasive. In the innermost layer of the bile duct, according to the American Cancer Society, the cancer is only in this period, known as the mucosa. It's not in other organs or any lymph nodes.

Stage III

Bile duct cancer involves one tumor that's started to invade into more layers of the wall of the bile duct just like the muscle layer, but hasn't attained any blood ships although stage.

Phase IV

Stage II cancer is separated by the National Cancer Institute into Stage IIA and IIB. Period IIB involves cancer that has spread to adjacent lymph nodes, along with either the bile duct, the wall, or the liver, gallbladder, pancreas or portal vein.

Phase III bile duct cancer is divided into two sub -periods, Stage IIIA. Stage IIIA is identified when the cancer has started to invade the chief arteries just like the portal vein or the hepatic artery, on 1 side of the liver, based on the American Cancer Society. Other organs and lymph glands are cancer-free. Cancer that's penetrated the deeper layers of tissue in the wall, and maybe developed through the wall into surrounding liver or fat tissue is encompassed by stage IIIB cancer. Cancer may take the primary blood vessels of the liver on 1 side. Nearby lymph nodes may have cancer in them, but distant organs are not malignant. In accordance with the National Cancer Institute, cancer which has spread to nearby organs like the colon, stomach, small bowel or abdominal wall may be also included by phase III cancer.
