Breast Cancer

Among all cancers in ladies, he takes consumers. In most cases, breast cancers develops inside 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 with the nipple along with the nipple with the field (Paget's disease of the breast). For the nodular cancers are seen as an the node creating a diameter of up to several centimeters. In some cases, a strong knot, is permeated with whitish layers tissue penetrating in the surrounding fat, in other people - a soft, juicy about the cut, splits easily. Diffuse prostate type of cancer is roofed for a considerable distance, the contours of 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 along the surface from the breast and many types of the iron is roofed having a dense shell.

In histological structure are the following kinds of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers 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 allowed to distinguish different degree of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which often has the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The factors behind cancer of the breast often are hormonal changes in the body: the entry into menopause, when there is a dynamic restructuring from the hormonal regulation with the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, your body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most responsive to these changes, the breast growth actually starts to dissolve and become replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role inside progression of breast cancers. The excess hormones in the body produces a favorable background for developing the illness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (greater than 1 year) to lessen the risk of developing cancer of the breast. On the other hand, abortion bring about hormonal "explosion" in the woman's body that could trigger the development of tumors. So far there is absolutely no consensus regarding the impact for the continuing development of tumors of hormonal contraceptive drugs, however it is believed that these drugs reduce potential risk of developing breast cancers, but increase the potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancers can cause harmful environmental factors: the planet, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a category of first-degree relatives with cancer of the breast (mothers and sisters) risk of creating a tumor increasing by greater than half - familial varieties of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't lead to cancer, but at the same time, create an unfavorable background for the development.

The reason behind breast cancers will be the outcomes of radiation, such as irradiation with 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 bring about cancer of the breast and female the reproductive system, with the excess fat in the body, it will become an outside endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are several forms with the growth of cancer of the breast:

- Nodular form, the most typical, is seen as an a dense knot of 0.5 to cm or even more, it can be seen as a all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" with the breast and skin. For the first two forms are characteristic signs and symptoms of inflammation: pain in the breast, a bright beautiful red colors of the skin it raises body temperature to 39 degrees C. In view of such symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, that are named and so are described these forms cancer of the breast. When tubular carcinoma breast cancer cover as being a "skin" of their contracting and decreasing in dimensions.

In certain cases, breast cancers manifests inside the form of metastases in the lymph nodes on the affected side, often does not detect the tumor itself - show hidden breast cancer.

For small tumors in the breast, any symptoms arise. The most observant as well as their husbands are able to detect tumor site within the gland by accident, but inside a large breast to detect small size hard knot. Revealed a knot could 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 really is stationary or slightly shifted, could be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a substantial size (a lot more than 3 - 5 cm and often 10-15 cm).

Need to gauge the surface in the skin over the tumor: the malignant process will probably be observed retraction with the skin, collecting in the folds, wrinkles, an indicator of "lemon peel" - an area swelling from the skin in the tumor, may be a direct tumor invasion to the skin surface, then it will become a bright red colorization and sprawl as "cauliflower."
