What are the phases of breast cancer progression?
breast cancer is generally divided into five main phases, from phase 0 to Stage IV. This method of monitoring the progression of breast cancer acts as a simplified way of categorization and organization of the disease. The classification gives medical experts and patients with breast cancer a means of understanding characteristics that breast cancer usually shows in every stage. For each phase, cancer is grouped according to the size of the tumor and to what extent cancer spreads in the body.
The first phase of breast cancer progression is phase 0 or in-seit carcinoma and occurs when abnormal cells grow in the milk canal or lobulus breast. At this stage, cancer is non -invasive and has not spread to the lymph nodes. In general, this early cancer stage cannot be detected through the breast test and it is more likely that it will be found on the arrival of the mammogram. If treatment or detection is delayed, cancer may proceed through the pipe walls.
Although Stage 0 can be considered cancer,It is often used to describe a precancerous state; Phase I is often considered the first real cancer phase. Together with stages I to IV progression of breast cancer, they apply to invasive forms of cancer. In other words, cancer cells have the ability to enter the surrounding normal tissue.
Both breast cancer Stadium I and II II are still limited to breast tissue. Stage I, cancer prognosis generally describes the formation of a small tumor of measuring less than 1 inch (around 2 centimeters). However, at the time of breast cancer progression in Phase II, the tumor begins to spread to several lymph nodes and axillary or armpits.
Breast cancer Phase II is further divided into two subclass, phase IIA and phase IIB. In general, phase IIA refers to cancer growth of less than 1 inch (around 2 centimeters), which is also affection of lymph nodes. Can also refer to a tumor of up to 2 inches (around 5 centimeters) that has not been spread yetto lymph nodes. Stage IIB, is more advanced than the IIA stage and is distinguished by tumors measuring between 1 to 2 inches (about 2 to 5 centimeters), which began to disperse into lymph nodes. Phase IIB diagnosis may also apply to tumors that are larger than this size, but have not yet spread to the lymph nodes.
As soon as breast cancer progresses to Phase III or later, the cancer tumor proceeds outside the local area of the breast. In Stage III, tumors are greater than 2 inches (about 5 centimeters) and can be further divided as phases IIIa, phase IIIB and phase IIIC. Phase IIIa describes cancer cells that are in the lymph nodes, but there is no tumor in the breast. Regardless of the size of the tumor in the breast, when cancer cells are combined in the lymph nodes, the condition is generally also described as Stage IIIa. Phase IIIB diagnosis usually shows that cancer has spread to breast or other close tissue skin, while phase cancer is spreading through lymphatic nodes into germsBones and pectoral bones.
In Stage IV, breast cancer progression is considered metastatic. This shows that cancer spreads through the lymphatic system or blood to distant parts of the body. At a time when cancer reaches this phase, it has the ability to spread virtually anywhere in the body. Organs commonly affected by advanced breast cancer include the brain, bones or lungs.
Breast cancer understanding can help patients better appreciate how far their condition has progressed. From a medical point of view, this information provides the basis for deciding how to aggressively treat the disease. Although breast cancer survival decreases as soon as cancer has spread outside the breasts, it does not mean toliide is unsuccessful. By combining different treatment options, such as chemotherapy, radiation therapy and surgical removal of the tumor, suffering breast cancer can improve their chances of survival of malignant breast cancer.
