Among breast cancer women, breast cancer takes the first place. This is most often carcinoma - a non-invasive tumor that develops inside the milk ducts.
Causes of Protocol Breast Cancer
The risk of cancer of the ducts of the breast is affected mainly by women who avoided pregnancies until adulthood or at all renounced motherhood.
Too long menstrual period in a woman also promotes the growth of a tumor in the chest (early onset of menstruation and belated menopause).
For hormonal reasons also include prolonged estrogen-progestin hormone therapy.
Increasing importance in the development of intra-cellular breast cancer doctors give the hereditary factor - the risk of the disease increases many times with the family of oncology of the breast.
Intra-ductular breast cancer - symptoms
The main symptoms of intra-cellular breast cancer are the presence of a tumor-like seal in the breast tissue and discharge from the nipple.
However, these minor signs may be absent. Then the tumor can be detected only if a mammogram is performed. Symptoms of protocol breast cancer on an X-ray examination are defined as microcalcinates - calcium-impregnated areas of the glandular tissue formed as a result of the decay of the carcinoma.
If you suspect a cancer, a woman is sent to a breast biopsy. The fence of suspicious tissues to the study allows you to confirm or deny the diagnosis.
Non-invasive intra-cellular cancer is considered to be harmless for a woman's life if it develops "in situ", that is, in a local place and only in a protocol lumen. Carcinoma is removed surgically, and radiation therapy is used to avoid relapses, as well as, if necessary, hormone treatment.
Invasive Protective Breast Cancer
An undetected protocol breast cancer has a good chance of escalating into a more aggressive form - invasive breast cancer. With this form, the oncological process goes to healthy breast tissue.
Infiltrative protocol breast cancer differs from cancer "in situ" in that pathological process involves the surrounding affected tissue duct. Symptoms of such a tumor are more pronounced. Invasive breast carcinoma looks like a dense uneven swelling, fixedly stuck together with glandular cells. A characteristic feature of invasive cancer is the retraction of the nipple or "goosebumps"
Also infiltrating breast cancer can occur 5-10 years after surgery for the removal of noninvasive ductal carcinoma, if no radiation has been performed, and not all cancer cells have died. Invasive and non-invasive relapses appear in a quarter and up to half of all operated women. The cases of tumor re-formation occur even 25 years after the primary disease, so all treatment and lifestyle of a woman with breast cancer should be aimed at the prevention and early detection of the disease.
