BREAST CANCER BASE

Gynecomastia is women's diseases, multiple, is benign lesions. Although some people think of benign breast disease can increase breast hyperplasia and the risk of breast cancer in breast cancer, but the general proliferation of breast cancer risk is very low. According to relevant information, simple hyperplasia in breast cancer risk to below 1%, cystic hyperplasia cancer risk of 2% to 4%. It had breast hyperplasia after the first should not be afraid, be relaxed, good emotional adjustment, especially each premenstrual mood changes when it should adjust well to listen to more music, some personal and meaningful social activities. While nodular hyperplasia closely observing the size, texture changes, regularly go to the hospital for check-specialist doctors, and if necessary should be done on some of the auxiliary, such as : ① right breast X-ray inspection hyperplasia, can be seen within the breast of Patchy performance, higher density nodular shadow, uneven density, edge fate unclear, irregular shape, or sometimes appeared Massive Ground Glass density increased video. ② B-hyperplasia of the breast screening, thickening of breast tissue can be seen, limitations or diffuse round or oval-shaped liquid dark and heterogeneous hypoechoic area, wall thickness and smooth edge. ③ near infrared scanning severe breast hyperplasia, breast transmittance reduced, and glass was hazy, gray clumps no obvious images of vascular running no change. Mild mammary hyperplasia patients Breast infrared scanning, under normal circumstances no abnormal transmission. ④ fine needle aspiration cytology trip can be seen in patients with lobular breast hyperplasia within the peripheral catheter, lobular or ductal lobular among other epithelial cell proliferation catheter change.

Research found that the use of estrogen and progesterone hormone replacement therapy for a breast cancer can increase the incidence of breast cancer twice.

Fred Hutchinson Cancer Research Center in Seattle, scientists above the age of 50 at least 537 patients with breast cancer were studied, their sick time in 1988-1990. Then they did not have the same 492 female breast cancer were compared. Scientists found that combination therapy for at least 6 months (average 4 years) with the incidence of lobular breast cancer is another group of patients was 2.6 times more.

The basic structure of the breast
Breast mainly by the glands, ducts, fatty tissue components. Breast glands from 15 to 20 Lobectpomy components, each lobe divided into several gland lobule, each gland lobule again from 10 ~ 100 acinar components. These small acinar arranged in and around the duct connected with, a number of small duct between pooled into lobular breast, a number of inter-lobular breast further consolidated into a whole lobe of the mammary duct, or lose duct. Duct lost a total of 15 to 20 to nipple radially arranged for the center gathered at the areola, the openings in the nipple. Losers duct in the nipple Department relatively narrow, followed swelling of the ampulla, known as losers duct sinus, the role of milk storage.
