What are the types of breast cancer

summary

Aunt Chen recently feels uncomfortable, has a serious sense of fatigue, breast still feel very painful, go to the hospital for examination, did not expect to be found breast cancer, let me introduce what kind of breast cancer.

What are the types of breast cancer

First: ductal carcinoma of the breast. This is the most common type of breast cancer. Ductal carcinoma of the breast can not be confined to the duct outside the duct and spread to nearby structures. The cancer cells are confined to the duct without breaking through the basement membrane of the duct wall. The cancer cells in the duct can be arranged as solid, cribriform, low papillary or tubular, and are no longer classified into subtypes.

Second, invasive ductal carcinoma. It is also the most common form of breast cancer. According to the American Cancer Society, when diagnosed, cancer has gone beyond the duct to spread to the surrounding wall structure, and even beyond the expansion of the breast duct to become metastatic cancer. In addition, there are some rare special types of invasive ductal carcinoma, such as breast cancer, tubular carcinoma, mucinous adenocarcinoma, papillary carcinoma, breast medullary carcinoma, cribriform carcinoma, breast cancer metaplasia and mixed carcinoma.

Third: lobular carcinoma. Lobular carcinoma occurs in the lobule, and the cancer cells do not break through the basal membrane of the terminal mammary duct or acinus. The lobule is enlarged, the duct and acinus are increased, and the lobule is obviously thickened, filled with nonpolar cancer cells. Triple negative breast cancer. These are the behaviors of breast cancer. The basal cell like breast cancer gene is usually HER-2 / neu negative, and the hormone receptor (including ER and PR) is also negative, so it is also called "triple negative breast cancer".

matters needing attention

Many people probably don't know that breast cancer is also divided into several types. Different types of breast cancer may have different treatment methods. Breast cancer is often divided into the above types clinically. Mastering this classification is conducive to our scientific understanding of breast cancer.
