Breast Cancer

Among all cancers in women, he takes the initial place. In most cases, cancer of the breast develops within 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 from the breast). For the nodular cancers are seen as a the node using a diameter of up to several centimeters. In some cases, a tight knot, is permeated with whitish layers tissue penetrating to the surrounding dimply skin, on other occasions - a soft, juicy on the cut, splits easily. Diffuse cancer of the prostate is included to get a considerable distance, the contours in 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 instances, the tumor spreads across the surface from the breast and all the iron is included having a dense shell.

In histological structure will be the following kinds of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive cancer of the breast can 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 level of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which in turn has got the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes within the body: the entry into menopause, should there be a dynamic restructuring of the hormonal regulation of the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, our bodies will go through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most responsive to these changes, the breast type tissue begins to dissolve and become replaced by fat.

Scientifically established that the female hormones estrogen-, plays a key role inside the development of cancer of the breast. The excess hormones inside 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 the birth and prolonged breastfeeding (a lot more than twelve months) to lessen the potential risk of developing cancer of the breast. On the other hand, abortion bring about hormonal "explosion" in a woman's body that could trigger the development of tumors. So far there is no consensus about the impact for the progression of tumors of hormonal contraceptive drugs, but it's thought that these drugs reduce the chance of developing cancer of the breast, but increase the risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancer might cause harmful environmental factors: environmental surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not bring about cancer, but concurrently, create an unfavorable background for the development.

The source of cancer of the breast will be the connection between radiation, for example 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 result in cancer of the breast and female reproductive :, with an excess fatty tissue inside the body, it might be an outside endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

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

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" from the breast and skin. For the first couple of forms are characteristic signs and symptoms of inflammation: pain from the breast, a bright red color of the skin it raises body's temperature to 39 degrees C. In view of the symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, which can be named and they are known as these forms breast cancer. When tubular carcinoma breast cancers cover as being a "skin" of the company's contracting and decreasing in size.

In some instances, cancer of the breast manifests in the form of metastases inside lymph nodes around the affected side, often doesn't detect the tumor itself - show hidden cancer of the breast.

For small tumors from the breast, any symptoms arise. The most observant females and their husbands are able to detect tumor site inside the gland by accident, but in a very large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks for 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 an important size (a lot more than three to five cm and quite often 10-15 cm).

Need to evaluate the surface of the skin over the tumor: the malignant process will likely be observed retraction in the skin, picking up inside folds, wrinkles, an indicator of "lemon peel" - a neighborhood swelling of the skin within the tumor, might be a direct tumor invasion to your skin surface, then it might be a bright red color and sprawl as "cauliflower."
