Invasive breast cancer
If a woman is diagnosed with breast cancer, the further course of the disease, like her prognosis, depends on the invasiveness of the cancer, in other words - infiltration. The danger of invasive cancer lies in the fact that by infiltrating nearby organs and tissues, a cancerous tumor changes their structure to a pathological one, then penetrating into the blood and lymphatic channels.
When migrating to all healthy areas of the body, more organs and tissues become infected with cancer. Distribution can reach a colossal scale even in a relatively short time, since with current lymph, pathogenic cells are carried throughout the lymphatic system, and with blood, in turn, to bodies.
Invasive Protective Cancer
The most common type of breast cancer is invasive protocol cancer. Cancer cells, formed from the ducts of the mammary gland, gradually migrate beyond it and capture the adipose tissue of the gland and its lobules.
Detection in the chest of a small compaction, with uneven edges, may be the first symptom of the disease. This neoplasm has a cohesion with the surrounding tissues, and the skin and nipple next to it are visibly drawn. This type of tumors has a property for a long time not to manifest, even with careful probing it is difficult to determine.
Invasive lobular carcinoma
With invasive lobular cancer, with the help of palpation of the chest, it is easy to identify a painful seal having a fairly firm consistency. This type of tumors is the least common and occupies about 15% and can be located both in one gland and afflict both breasts. It usually occurs in elderly women of retirement age.
Invasive unspecified cancer
Invasive unspecified cancer is diagnosed in the case when morphology does not determine its shape. In this case, an additional immunohistochemical test is required, which will help to calculate the type of tumor.
For example, medullar cancer is characterized by a low degree of invasiveness and large tumor size. Inflammatory cancer resembles mastitis, as the symptoms are quite similar. It begins with the detection of infiltration, redness of the skin of the breast and fever.
Infiltrating ductal cancer
Gives rapid metastases, germinating in nearby tissues and organs, forming nests and cords in them. He takes 70% of cases.
There is also a cancer that affects the halos of the breast and nipple (Paget's cancer). It is easily confused with eczema, according to a similar symptom of redness. He has a more unfavorable prognosis than the above types of tumors.
The hormone-dependent tumors usually appear in postmenopause and have estrogen receptors, that is, their growth and development depend a lot on the development of this hormone.
Depending on the degree of development of the disease and its stage, the necessary treatment is determined.
The main method in the treatment of invasive breast cancer is a surgical operation, in which the segment or part of the gland is removed. If the invasive cancer has reached the underlying muscles - they also need to be removed. Before the operation determine the size and location of the tumor, since in case it is in an inoperable place, it will not be removed.
After removal of the main cancers, radiation therapy or chemotherapy should be followed. It is used to prevent recurrence of the disease.
Hormone therapy is necessary to prevent the influence of certain female hormones on cancer cells, their growth and division. To do this, special drugs are prescribed that suppress the production of certain sex hormones.
In the event that invasive breast cancer has led to extensive metastases, the disease is considered incurable, since it is impossible to cope with numerous foci in the entire body. However, treatment is still ongoing, supporting therapy is being used..
