Breast Cancer

Among all cancers in ladies, he takes the initial place. In most cases, breast cancer 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, as well as cancer from the nipple along with the nipple of the field (Paget's disease from the breast). For the nodular cancers are seen as the node having a diameter all the way to several centimeters. In some instances, a tight knot, is permeated with whitish layers tissue penetrating into the surrounding dimply skin, in other people - a soft, juicy for the cut, splits easily. Diffuse prostate type of cancer is roofed for a considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads along the surface from the breast and all the iron is included having a dense shell.

In histological structure are the following types of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers could be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is seen as an varying examples of tissue and cell irregularities, which allowed to distinguish different amount of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which usually has the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

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

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

In addition, patients having a group 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 tend not to result in cancer, but as well, create an unfavorable background for its development.

The reason behind breast cancers will be the effects of radiation, for example 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 lead to cancer of the breast and female reproductive :, with an excess fatty tissue inside the body, it might be another endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are several forms of the growth of breast cancers:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" with the breast and skin. For the initial two forms are characteristic signs of inflammation: pain from the breast, a bright beautiful red colors of the skin it raises body's temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, which can be named and therefore are described these forms breast cancers. When tubular carcinoma breast cancer cover like a "skin" of their contracting and decreasing in space.

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

For small tumors of the breast, any symptoms arise. The most observant women and their husbands have the ability to detect tumor site within the gland by chance, but inside a large breast to detect small size hard knot. Revealed a knot might 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, might be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a substantial size (more than 3 - 5 cm and sometimes 10-15 cm).

Need to gauge the surface from the skin within the tumor: the malignant process will likely be observed retraction from the skin, obtaining within the folds, wrinkles, a signal of "lemon peel" - an area swelling in the skin in 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."
