Breast Cancer

Among all cancers ladies, he takes the first place. In most cases, breast cancers 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 from the nipple along with the nipple in the field (Paget's disease with the breast). For the nodular cancers are characterized by the node creating a diameter up to several centimeters. In certain cases, a decent 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 cancer is covered 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 down the surface in the breast and all sorts of the iron is included which has a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as a varying levels of tissue and cell irregularities, which able to distinguish different amount of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which often contains the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

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

Scientifically established how the female hormones estrogen-, plays an integral role within the continuing development of breast cancers. The excess hormones inside the body creates a favorable background for developing the disease. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (over 1 year) to lessen the risk of developing breast cancer. On the other hand, abortion lead to hormonal "explosion" in a very woman's body that will trigger the growth and development of tumors. So far there's no consensus regarding the impact about the continuing development of tumors of hormonal contraceptive drugs, yet it's belief that these drugs reduce potential risk of developing breast cancers, but increase the potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: environmental surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a family of first-degree relatives with breast cancer (mothers and sisters) probability of making a tumor increasing by greater than half - familial forms of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not cause cancer, but at the same time, create an unfavorable background for its development.

The source of breast cancers will be the outcomes of radiation, including 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 cause cancer from the breast and female reproductive system, with an excess dimply skin inside body, it is a separate endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are a couple of forms from the growth of breast cancers:

- Nodular form, the most typical, is seen as a dense knot of 0.5 to 5 cm or more, it is characterized by 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 2 forms are characteristic signs and symptoms of inflammation: pain of the breast, a bright red colorization in the skin it raises temperature to 39 degrees C. In view of such symptoms often occur, and errors in carried out patients treated for inflammatory diseases, which can be named and so are described these forms breast cancer. When tubular carcinoma breast cancers cover like a "skin" of the company's contracting and decreasing in space.

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

For small tumors from the breast, any symptoms arise. The most observant ladies and their husbands can detect tumor site inside the gland accidentally, but in the large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks in support of 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 a tremendous size (more than 3 - 5 cm and infrequently 10-15 cm).

Need to assess the surface in the skin in the tumor: the malignant process will probably be observed retraction from the skin, buying inside the folds, wrinkles, a signal of "lemon peel" - a local swelling of the skin over the tumor, is often a direct tumor invasion to your skin layer surface, then it is a bright red color and sprawl as "cauliflower."
