Breast Cancer

Among all cancers in women, he takes the ultimate 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 and also the nipple with the field (Paget's disease from the breast). For the nodular cancers are characterized by the node using a diameter of up to several centimeters. In some cases, a good knot, is permeated with whitish layers tissue penetrating in to the surrounding dimply skin, in others - a soft, juicy about the cut, splits easily. Diffuse prostate type of cancer is covered for the considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades your skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads along the surface from the breast and the iron is included using a dense shell.

In histological structure include the following kinds of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying degrees of tissue and cell irregularities, which able to distinguish different level of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which usually has the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The causes of breast cancers often are hormonal changes inside the body: the entry into menopause, if you find an active restructuring of the hormonal regulation of the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, our bodies is going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most understanding of these changes, the breast tissue begins to dissolve and be replaced by fat.

Scientifically established how the female hormones estrogen-, plays an integral role within the continuing development of breast cancers. The excess hormones in the body creates a favorable background for developing the sickness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (more than one year) to relieve the potential risk of developing breast cancers. On the other hand, abortion bring about hormonal "explosion" in a very woman's body that may trigger the progression of tumors. So far there is absolutely no consensus in regards to the impact about the development of tumors of hormonal contraceptive drugs, however it is believed that these drugs reduce the potential risk of developing breast cancers, 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 surroundings, along with inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases including 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 cause of breast cancer would be the connection between radiation, such as 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 result in cancer with the breast and female reproductive system, by having an excess dimply skin inside body, it becomes a different endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

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

- Nodular form, the most typical, is seen as a dense knot of 0.5 to 5 cm or higher, it really is seen as a all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" in the breast and skin. For the first 2 forms are characteristic signs of inflammation: pain with the breast, a bright red color in the skin it raises temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that happen to be named and therefore are known these forms breast cancers. When tubular carcinoma breast cancer cover like a "skin" of the company's contracting and decreasing in dimensions.

In certain cases, cancer of the breast manifests inside form of metastases in the lymph nodes about the affected side, often doesn't detect the tumor itself - show hidden breast cancers.

For small tumors in the breast, any symptoms arise. The most observant ladies and their husbands are able to detect tumor site in the gland by accident, but in a very large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks in support of a benign tumor. Signs of malignancy other: a strong knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, may be firmly fixed on the surrounding tissue or skin, usually painless, can reach a significant size (a lot more than three to five cm and infrequently 10-15 cm).

Need to gauge the surface in the skin over the tumor: the malignant process will likely be observed retraction with the skin, buying within the folds, wrinkles, an indication of "lemon peel" - a nearby swelling from the skin over the tumor, may be a direct tumor invasion to the skin surface, then it might be a bright beautiful red colors and sprawl as "cauliflower."
