Breast Cancer

Among all cancers in ladies, he takes consumers. 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, in addition to cancer of the nipple along with the nipple from the field (Paget's disease of the breast). For the nodular cancers are seen as a the node creating a diameter as high as several centimeters. In certain instances, a strong knot, is permeated with whitish layers tissue penetrating in the surrounding fatty tissue, on other occasions - a soft, juicy for the cut, splits easily. Diffuse cancer of the prostate is covered for the considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades your skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads over the surface with the breast and the iron is included which has a dense shell.

In histological structure would be the following varieties 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 levels of tissue and cell irregularities, which in a position to distinguish different a higher level malignancy. This type of cancer include, specifically, 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 cancers often are hormonal changes inside body: the entry into menopause, when there is an engaged restructuring in the hormonal regulation of the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, your body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most tuned in to these changes, the breast growth begins to dissolve and become 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 creates a favorable background for developing the illness. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (a lot more than one year) to lessen the chance of developing breast cancer. On the other hand, abortion lead to hormonal "explosion" in a woman's body that may trigger the development of tumors. So far there is no consensus concerning the impact around the growth and development of tumors of hormonal contraceptive drugs, however it is thought that these drugs reduce the potential risk of developing cancer of the breast, but increase the chance of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancer can cause harmful environmental factors: the surroundings, in addition to inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to result in cancer, but simultaneously, create an unfavorable background for the development.

The cause of cancer of the breast may be the outcomes of radiation, such as irradiation of 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 cause cancer in the breast and female the reproductive system, having an excess fatty tissue within the body, it becomes another endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are many forms from the growth of cancer of the breast:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" from the breast and skin. For the first 2 forms are characteristic warning signs of inflammation: pain in the breast, a bright red colorization of the skin it raises body temperature to 39 degrees C. In view of the symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that happen to be named and they are known these forms breast cancer. When tubular carcinoma cancer of the breast cover as a "skin" of their contracting and decreasing in proportions.

In some instances, cancer of the breast manifests within the form of metastases in the lymph nodes about 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 within the gland accidentally, but in the large breast to detect small size hard knot. Revealed a knot may 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 is stationary or slightly shifted, can be firmly fixed for the surrounding tissue or skin, usually painless, can reach a significant size (more than 3 - 5 cm and quite often 10-15 cm).

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