Breast Cancer

Among all cancers in women, he takes the initial place. 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, along with cancer from the nipple and also the nipple from the field (Paget's disease in the breast). For the nodular cancers are seen as an the node using a diameter up to several centimeters. In some cases, a decent knot, is permeated with whitish layers tissue penetrating to the surrounding fatty tissue, on other occasions - a soft, juicy for the cut, splits easily. Diffuse cancer of the prostate is roofed for a considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades your skin layer and forms around the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads over the surface with the breast and many types of the iron is roofed using a dense shell.

In histological structure include the following kinds of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying examples of tissue and cell irregularities, which in a position to distinguish different amount of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which in turn has the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The reasons behind cancer of the breast often are hormonal changes inside body: the entry into menopause, should there be an active restructuring from the hormonal regulation from the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, one's body will go through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most tuned in to these changes, the breast growth actually starts to dissolve and stay replaced by fat.

Scientifically established how the female hormones estrogen-, plays an integral role within the continuing development of breast cancer. The excess hormones in the body produces a favorable background for developing the disease. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (greater than twelve months) to relieve the risk of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" in a very woman's body that will trigger the development of tumors. So far there is absolutely no consensus regarding the impact about the continuing development of tumors of hormonal contraceptive drugs, but it is thought that these drugs reduce the potential risk of developing breast cancer, but increase the potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: the environment, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a family of first-degree relatives with breast cancer (mothers and sisters) risk of creating a tumor increasing by more than half - familial forms of cancer.

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to bring about cancer, but as well, create an unfavorable background because of its development.

The cause of breast cancer may be the outcomes of radiation, including 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 with the breast and female the reproductive system, by having an excess dimply skin inside the body, it might be a different endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are some forms from the growth of breast cancer:

- Nodular form, the most typical, is characterized by a dense knot of 0.5 to 5 cm or maybe more, it can be seen as a all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" in the breast and skin. For the first couple of forms are characteristic indications of inflammation: pain with the breast, a bright red color of the skin it raises body's temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, which can be named and so are described these forms breast cancer. When tubular carcinoma breast cancer cover being a "skin" of its contracting and decreasing in space.

In some instances, cancer of the breast manifests in the form of metastases in the lymph nodes for 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 are able to detect tumor site inside gland by accident, but in a 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 decent knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (over 3 to 5 cm and quite often 10-15 cm).

Need to assess the surface from the skin in the tumor: the malignant process will probably be observed retraction of the skin, buying inside folds, wrinkles, an indication of "lemon peel" - a local swelling with the skin over the tumor, might be a direct tumor invasion to your skin layer surface, then it becomes a bright beautiful red colors and sprawl as "cauliflower."
