A higher incidence of breast cancer, has become the most common cancer in women. Key is early detection and early treatment, physical examination and testing of the universal means of improving significantly reduced breast cancer mortality, it is generally believed that only women will get breast cancer, in fact, men can also develop breast cancer, but relatively rare. So what is breast cancer? What is Breast Cancer Risk? What kind of lymphatic metastasis of breast cancer will be? Need to understand these needs from the start with the construction of the breast:
First, the construction of the breast
From material consisting of lobules of fat, connective tissue and glandular tissue. In the production, the leaflet can produce milk. Through the input duct lobular connected with the nipple. Lobular breast cancer, usually from the end of coverage (in this case, lobular and duct connected to the input) and duct cells and transmission to begin. The skin under the breast tissue of the “tail” to their armpits. Also contains a number of lymph nodes under the armpit (also called lymph nodes), lymph nodes are part of the lymphatic system.
Second, what is breast cancer
Abnormal cells in breast cancer are unable to control the organization of regional growth. It can be malignant (cancerous) or benign. Out of every ten breast lumps are not cancerous in nine, but fibroadenoma and cysts. For more information, please see the separate BUPA profile, breast lumps. The growth of cancerous tumors can be through the breast, spread to other parts of the body (through the bloodstream or lymphatic system), and can be growing there, form a “secondary” tumor. This is called metastasis.
Third, what type of breast cancer will be transferred
There are different types of breast cancer, according to the ability to spread into the neighboring non-invasive breast cancer and invasive breast cancer, only the invasive breast cancer in lymph node metastasis will occur.
1 non-invasive breast cancer
Non-invasive breast cancer, the most common type is ductal carcinoma in situ (DCIS). Can only be found in the input duct cancer cells, cancer cells do not lose milk through the wall into the breast tissue. Sometimes, DCIS may develop into invasive breast cancer.
2 invasive breast cancer
The most common type of invasive breast cancer called invasive ductal carcinoma (IDC). Every four breast cancer patients, about three people with this type of breast cancer. Catheter and breast cancer cells in the organization, but can be extended to other parts of the body.
Invasive lobular carcinoma (ILC) is a lobular breast cancer cells initially grow, but can be extended to other regions, as well as breast cancer in other parts of the body.
