Breast Cancer

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

In histological structure include the following kinds of breast cancer:

• 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 seen as an varying levels of tissue and cell irregularities, which in a position to distinguish different amount of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which usually gets the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The reasons for cancer of the breast often are hormonal changes inside body: the entry into menopause, should there be an energetic restructuring of the hormonal regulation of the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, one's body is going through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most tuned in to these changes, the breast tissue actually starts to dissolve and turn into replaced by fat.

Scientifically established that this female hormones estrogen-, plays a key role within the 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 when pregnant and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (over 12 months) to reduce potential risk of developing cancer of the breast. On the other hand, abortion lead to hormonal "explosion" inside a woman's body that will trigger the growth and development of tumors. So far there is no consensus in regards to the impact on the continuing development of tumors of hormonal contraceptive drugs, but it's believed that these drugs reduce the risk of developing breast cancer, but increase potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: the planet, along with inflammatory diseases previously deferred breast - mastitis.

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

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

The cause of breast cancers would 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 bring about cancer from the breast and female reproductive system, with an excess fatty tissue inside the body, it becomes a separate endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

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

- Nodular form, the most typical, is characterized by a dense knot of 0.5 to 5 cm or more, it's seen as an all of the following symptoms;

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

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

For small tumors from the breast, any symptoms arise. The most observant women 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 can 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 is stationary or slightly shifted, might be firmly fixed on the surrounding tissue or skin, usually painless, can reach a significant size (greater than 3 to 5 cm and sometimes 10-15 cm).

Need to gauge the surface of the skin within the tumor: the malignant process will be observed retraction in the skin, collecting inside the folds, wrinkles, an indicator of "lemon peel" - a local swelling of the skin over the tumor, is often a direct tumor invasion to skin surface, then it will become a bright red color and sprawl as "cauliflower."
