Breast Cancer

Among all cancers in women, he takes consumers. In most cases, breast cancer develops in the presence of precancerous changes. This is primarily a benign mammary dysplasia and papilloma ducts.

Breast cancer is represented macroscopically nodular and diffuse forms, in addition to cancer in the nipple and also the nipple of the field (Paget's disease with the breast). For the nodular cancers are seen as a the node developing a diameter all the way to several centimeters. In some instances, a tight knot, is permeated with whitish layers tissue penetrating in the surrounding fat, on other occasions - a soft, juicy around the cut, splits easily. Diffuse prostate cancer is roofed to get a considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades your skin layer and forms on the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads over the surface in the breast and many types of the iron is roofed having a dense shell.

In histological structure include the following varieties of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancer could be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is seen as varying levels of tissue and cell irregularities, which in a position to distinguish different a higher level malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which in turn contains the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The causes of breast cancers often are hormonal changes inside body: the entry into menopause, when there is a dynamic restructuring from the hormonal regulation of the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, our bodies is going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most understanding of these changes, the breast growth begins to dissolve and become replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role within the development of breast cancers. The excess hormones within the body creates a favorable background for developing the condition. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (a lot more than one year) to relieve the chance of developing cancer of the breast. On the other hand, abortion result in hormonal "explosion" in the woman's body that could trigger the development of tumors. So far there is absolutely no consensus about the impact about the continuing development of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce the chance of developing breast cancers, but increase the potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancers can cause harmful environmental factors: the environment, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients having a category of first-degree relatives with cancer of the breast (mothers and sisters) chance of making a tumor increasing by more than half - familial forms of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't cause cancer, but simultaneously, create an unfavorable background for the development.

The reason for breast cancer will be the effects of radiation, for example irradiation in the chest for other diseases (lung tumors, the lymphatic system), prolonged and frequent chest X-ray studies on inflammatory diseases or pulmonary tuberculosis.

Constitutional obesity can result in cancer from the breast and female reproductive :, with an excess dimply skin in the body, it will become an outside endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are many forms of the growth of cancer of the breast:

- Nodular form, the most typical, is seen as a a dense knot of 0.5 to five cm or higher, it is seen as all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" with the breast and skin. For the initial two forms are characteristic signs and symptoms of inflammation: pain in the breast, a bright red color from the skin it raises body's temperature to 39 degrees C. In view of those symptoms often occur, and errors in carried out patients treated for inflammatory diseases, that are named and so are known these forms breast cancers. When tubular carcinoma cancer of the breast cover being a "skin" of its contracting and decreasing in proportions.

In some instances, breast cancer manifests inside the form of metastases within the lymph nodes on the affected side, often ceases to detect the tumor itself - show hidden cancer of the breast.

For small tumors of the breast, any symptoms arise. The most observant women and their husbands have the ability to detect tumor site inside gland accidentally, but in a very large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, might be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a tremendous size (greater than 3 - 5 cm and quite often 10-15 cm).

Need to assess the surface of the skin on the tumor: the malignant process will likely be observed retraction in the skin, buying within the folds, wrinkles, an indication of "lemon peel" - a neighborhood swelling of the skin in the tumor, may be a direct tumor invasion to your skin layer surface, then it might be a bright red colorization and sprawl as "cauliflower."
