For the nodular cancers are seen as an the node having a diameter all the way to several centimeters. In some cases, a decent knot, is permeated with whitish layers tissue penetrating into the surrounding dimply skin, on other occasions - a soft, juicy for the cut, splits easily. Diffuse cancer of the prostate is included for the considerable distance, the contours of the tumor are marked bad.

In histological structure will be the following forms of cancer of the breast:

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

Infiltrating (invasive) cancer is seen as varying examples of tissue and cell irregularities, which able to distinguish different level of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which will contains the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancer often are hormonal changes inside body: the entry into menopause, if you find a dynamic restructuring of the hormonal regulation in the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, our bodies is going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most attentive to these changes, the breast tissue actually starts to dissolve and be replaced by fat.

Scientifically established how the female hormones estrogen-, plays an integral role inside growth and development of breast cancers. The excess hormones inside the body results in a favorable background for developing the illness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (more than 1 year) to reduce the potential risk of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" in a woman's body that can trigger the continuing development of tumors. So far there's no consensus about the impact around the development of tumors of hormonal contraceptive drugs, but it is belief that these drugs reduce the chance of developing cancer of the breast, but increase the potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast could cause harmful environmental factors: environmental surroundings, along with inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a category of first-degree relatives with cancer of the breast (mothers and sisters) probability of creating a tumor increasing by over half - familial forms of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to cause cancer, but simultaneously, create an unfavorable background because of its development.

The reason behind cancer of the breast will be the results 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 from the breast and female reproductive system, having an excess fat inside body, it will become an outside endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

- 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 initial two forms are characteristic signs and symptoms of inflammation: pain from the breast, a bright red colorization of the skin it raises body's temperature to 39 degrees C. In view of the symptoms often occur, and errors in carried out patients treated for inflammatory diseases, that are named and therefore are known these forms breast cancers. When tubular carcinoma cancer of the breast cover like a "skin" of the contracting and decreasing in dimensions.

In certain cases, breast cancers manifests inside form of metastases inside the lymph nodes about the affected side, often doesn't detect the tumor itself - show hidden cancer of the breast.

Revealed a knot could be painful when pressed, round, smooth and agile, this speaks for a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, may be firmly fixed on the surrounding tissue or skin, usually painless, can reach a tremendous size (more than 3 to 5 cm and infrequently 10-15 cm).
