Breast Cancer

Among all cancers in ladies, he takes the ultimate 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, and also cancer of the nipple along with the nipple in the field (Paget's disease with the breast). For the nodular cancers are seen as an the node having a diameter of up to several centimeters. In some instances, a decent knot, is permeated with whitish layers tissue penetrating in to the surrounding dimply skin, on other occasions - a soft, juicy for the cut, splits easily. Diffuse prostate type of cancer is included to get a 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 instances, the tumor spreads over the surface from the breast and the iron is covered using a dense shell.

In histological structure would be the following varieties of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive cancer of the breast may be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

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

Causes of Breast Cancer.

The reasons for breast cancer often are hormonal changes inside body: the entry into menopause, if you find an engaged restructuring from the hormonal regulation of the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, your body is going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most attentive to these changes, the breast tissue begins to dissolve and become replaced by fat.

Scientifically established how the female hormones estrogen-, plays a key role inside growth and development of cancer of the breast. The excess hormones in the body produces a favorable background for developing the disease. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (over 12 months) to lessen potential risk of developing cancer of the breast. On the other hand, abortion cause hormonal "explosion" in a very woman's body that can trigger the continuing development of tumors. So far there is absolutely no consensus concerning the impact around the development of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce the potential risk of developing breast cancer, but increase the risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancers could cause harmful environmental factors: the planet, as well as inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't lead to cancer, but concurrently, create an unfavorable background for the development.

The reason for cancer of the breast may be the effects of radiation, including 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 lead to cancer of the breast and female reproductive system, with an excess fat inside the body, it will become a separate endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are several forms of the growth of breast cancers:

- Nodular form, the most common, is seen as a dense knot of 0.5 to cm or more, it can be seen as an all with the following symptoms;

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

In some cases, breast cancer manifests inside form of metastases within the lymph nodes on the affected side, often ceases to detect the tumor itself - show hidden breast cancer.

For small tumors with the breast, any symptoms arise. The most observant as well as their husbands are able to detect tumor site inside gland unintentionally, but in a large breast to detect small size hard knot. Revealed a knot can be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a tight 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 a substantial size (over three to five cm and infrequently 10-15 cm).

Need to evaluate the surface from the skin over the tumor: the malignant process is going to be observed retraction from the skin, obtaining within the folds, wrinkles, an indicator of "lemon peel" - a neighborhood swelling with the skin in the tumor, is often a direct tumor invasion to your skin layer surface, then it will become a bright red color and sprawl as "cauliflower."
