The basic principles of breast cancer treatment is the removal of the visible edge of the tumor and surrounding normal tissue, and make sure to reach the safety line around the tumor. The extent of resection depends on each individual, from surgeons and pathologists to the removal of the tumor infiltrating the organization to evaluate the extent and location.
Very small tumors excision is sufficient, the majority of early breast cancer section can be removed only in the larger quadrant tumor resection.
If it is advanced tumor or has spread to the entire breast removed to completely remove the majority of breast cancer would have to determine the amount of removal of the organization before the wise surgeon and the patient must discuss mastectomy. Radical surgery, such as the Halsted radical mastectomy (removal of the chest wall muscles) only Aikuai fixed to the muscles on the use of a very late stage.
As a surgical component having to remove lymph nodes to determine the scope of cancer. Cancer found in lymph nodes that have moved beyond the breast and microscopic axillary risk (can not be touched in time), may reach the lungs, liver, bone. Lymph node-positive fruit usually means need additional adjuvant therapy – hormone therapy and chemotherapy. If the node-negative, the lower the possibility of distant metastasis, removal of lymph nodes for generating no difference.
Sentinel lymph node dissection is an investigational new technology, surgeons used blue dye is sometimes the use of radioisotopes, marking the first one may incorporate cancer axillary lymph nodes, removal of sentinel lymph node biopsy, if negative, the other lymph nodes metastasis of the possibility of a small. If the sentinel lymph node was positive for the need to remove all the other lymph nodes.
Has now recognized down, axillary lymph node is not an effective barrier to prevent the spread of cancer. Axillary lymph node excision is not a cure measures, but provide us with the tumor-fat, transfer risk and to better determine the need for adjuvant treatment of information. Removal of all or part of the lymph nodes, respectively, said the cleaning and removal, breast cancer surgery at the same time, a separate incision may or may not at the same time. Most patients require lymph node dissection, only the results from the impact of treatment decision-making can be omitted.
