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 in the nipple and the nipple of the field (Paget's disease in the breast). For the nodular cancers are seen as the node creating a diameter as high as several centimeters. In certain instances, a decent knot, is permeated with whitish layers tissue penetrating in the surrounding dimply skin, in others - a soft, juicy around the cut, splits easily. Diffuse cancer of the prostate is roofed for a considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades your skin layer 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 many types of the iron is covered having a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as a varying degrees of tissue and cell irregularities, which in a position to distinguish different degree of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which often contains the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The factors behind cancer of the breast often are hormonal changes inside body: the entry into menopause, if you have an engaged restructuring from the hormonal regulation in the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, the body goes through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most responsive to these changes, the breast tissue begins to dissolve and turn into replaced by fat.

Scientifically established the female hormones estrogen-, plays an integral role within the progression of breast cancers. The excess hormones inside body creates a favorable background for developing the illness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (more than twelve months) to cut back the risk of developing breast cancer. On the other hand, abortion lead to hormonal "explosion" inside a woman's body that will trigger the development of tumors. So far there is no consensus regarding the impact on the progression of tumors of hormonal contraceptive drugs, but it is believed that these drugs reduce potential risk of developing breast cancers, but increase the risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast can cause harmful environmental factors: environmental surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a category of first-degree relatives with breast cancer (mothers and sisters) probability of making a tumor increasing by over half - familial types of cancer.

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't bring about cancer, but simultaneously, create an unfavorable background because of its development.

The reason behind breast cancers could be the results 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 of the breast and female reproductive system, having an excess fat inside the body, it will become a different endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are some forms from the growth of breast cancers:

- Nodular form, the commonest, is seen as a a dense knot of 0.5 to five cm or even more, it's seen as an all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" in the breast and skin. For the first 2 forms are characteristic signs of inflammation: pain from the breast, a bright red color in the skin it raises body 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 are known these forms breast cancers. When tubular carcinoma cancer of the breast cover as being a "skin" of the company's contracting and decreasing in dimensions.

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

For small tumors of the breast, any symptoms arise. The most observant ladies and their husbands are able to detect tumor site inside the gland accidentally, but inside a 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 really is stationary or slightly shifted, could be firmly fixed for the surrounding tissue or skin, usually painless, can reach an important size (more than three to five cm and sometimes 10-15 cm).

Need to assess the surface with the skin in the tumor: the malignant process will likely be observed retraction in the skin, obtaining within the folds, wrinkles, a symptom of "lemon peel" - an area swelling of the skin within the tumor, might be a direct tumor invasion to your skin layer surface, then it will become a bright beautiful red colors and sprawl as "cauliflower."
