Breast Cancer

Among all cancers in ladies, 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, in addition to cancer from the nipple and the nipple in the field (Paget's disease in the breast). For the nodular cancers are seen as an the node developing a diameter up to several centimeters. In some instances, a strong knot, is permeated with whitish layers tissue penetrating to the surrounding dimply skin, in others - a soft, juicy on the cut, splits easily. Diffuse prostate type of cancer is included for a considerable distance, the contours from 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 from the breast and all sorts of the iron is covered which has a dense shell.

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

• 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 an varying degrees 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 will has the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancers often are hormonal changes in the body: the entry into menopause, if you find an energetic restructuring of the hormonal regulation from the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, our bodies goes through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most responsive to these changes, the breast type tissue 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 inside body produces a favorable background for developing the illness. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (greater than twelve months) to relieve the chance of developing breast cancers. On the other hand, abortion bring about hormonal "explosion" in a very woman's body that can trigger the growth and development of tumors. So far there is no consensus about the impact for the continuing development of tumors of hormonal contraceptive drugs, yet it's considered that these drugs reduce the risk of developing breast cancer, but increase potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancers could cause harmful environmental factors: the environment, along with inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't result in cancer, but at the same time, create an unfavorable background due to the development.

The source of breast cancers could be the results of radiation, such as 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 lead to cancer in the breast and female reproductive :, with an excess dimply skin inside the body, it might be a different endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

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

- Nodular form, the most common, is characterized by a dense knot of 0.5 to cm or maybe more, it can be characterized by 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 of the breast, a bright red color from the skin it raises body temperature to 39 degrees C. In view of those symptoms often occur, and errors in carried out patients treated for inflammatory diseases, that happen to be named and so are described these forms breast cancers. When tubular carcinoma breast cancer cover as a "skin" of their contracting and decreasing in dimensions.

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

For small tumors of the breast, any symptoms arise. The most observant females and their husbands have the ability to detect tumor site within the gland accidentally, 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 tight knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, could be firmly fixed on the surrounding tissue or skin, usually painless, can reach an important size (more than three to five cm and infrequently 10-15 cm).

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