Breast Cancer

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

In histological structure are the following forms of cancer of the breast:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancer can 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 allowed to distinguish different level of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which in turn contains the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The reasons for breast cancers often are hormonal changes inside body: the entry into menopause, if you find a dynamic restructuring with the hormonal regulation of 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 responsive to these changes, the breast tissue starts to dissolve and become replaced by fat.

Scientifically established that the female hormones estrogen-, plays an important role within the growth and development of cancer of the breast. The excess hormones within the body results in a favorable background for developing the sickness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (a lot more than one year) to cut back potential risk of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" in a woman's body that may trigger the growth and development of tumors. So far there is absolutely no consensus in regards to the impact on the growth and development of tumors of hormonal contraceptive drugs, but it is thought that these drugs reduce the chance of developing breast cancers, but increase potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancer could cause harmful environmental factors: the environment, along with inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to lead to cancer, but as well, create an unfavorable background because of its development.

The cause of breast cancers may be the connection between 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 result in cancer from the breast and female the reproductive system, with an excess fatty tissue inside the body, it is an outside endocrine organ and begins 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 breast cancers:

- Nodular form, the most frequent, is seen as a dense knot of 0.5 to 5 cm or more, it is seen as a all from the following symptoms;

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

In some cases, breast cancer manifests inside form of metastases inside lymph nodes for the affected side, often does not detect the tumor itself - show hidden breast cancers.

For small tumors from the breast, any symptoms arise. The most observant females and their husbands can detect tumor site in the gland unintentionally, but in a very large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks in favor 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, could be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a substantial size (greater than 3 to 5 cm and quite often 10-15 cm).

Need to evaluate the surface with the skin in the tumor: the malignant process will be observed retraction with the skin, buying in the folds, wrinkles, an indicator of "lemon peel" - an area swelling in the skin in the tumor, may be a direct tumor invasion to your skin layer surface, then it might be a bright red color and sprawl as "cauliflower."
