Among all cancers in ladies, he takes the first place. In most cases, breast cancers 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 of the nipple and the nipple of the field (Paget's disease of the breast). For the nodular cancers are seen as a the node using a diameter of up to several centimeters. In certain cases, a tight knot, is permeated with whitish layers tissue penetrating in the surrounding dimply skin, in others - a soft, juicy on the cut, splits easily. Diffuse prostate type of cancer is covered for any considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades your skin layer and forms about the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads over the surface in the breast and all 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 cancer can be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

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

Causes of Breast Cancer.

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

Scientifically established that this female hormones estrogen-, plays an important role inside the development of breast cancer. The excess hormones within the body results in a favorable background for developing the illness. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (greater than 12 months) to lessen the chance of developing cancer of the breast. On the other hand, abortion cause hormonal "explosion" in a very woman's body that could trigger the growth and development of tumors. So far there isn't any consensus about the impact around the development of tumors of hormonal contraceptive drugs, however it is thought that these drugs reduce the chance of developing breast cancers, but increase the chance of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast can cause harmful environmental factors: the planet, in addition to inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't result in cancer, but as well, create an unfavorable background due to the development.

The reason behind breast cancers may be the effects of radiation, like 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 with the breast and female reproductive :, having an excess dimply skin inside body, it becomes a different endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are a couple of forms of the growth of cancer of the breast:

- Nodular form, the most frequent, is characterized by a dense knot of 0.5 to cm or more, it's seen as a all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" of the breast and skin. For the first couple of forms are characteristic indications 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 diagnosing patients treated for inflammatory diseases, that are named and are described these forms cancer of the breast. When tubular carcinoma breast cancers cover as a "skin" of its contracting and decreasing in dimensions.

In certain cases, cancer of the breast manifests within the form of metastases in the lymph nodes for the affected side, often ceases to detect the tumor itself - show hidden breast cancers.

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

Need to gauge the surface with the skin on the tumor: the malignant process will probably be observed retraction of the skin, buying inside folds, wrinkles, a symptom of "lemon peel" - a neighborhood swelling of the skin in the tumor, may be a direct tumor invasion to the skin surface, then it might be a bright red colorization and sprawl as "cauliflower."
