Breast Cancer

Among all cancers ladies, he takes the first 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, along with cancer in the nipple as well as the nipple from the field (Paget's disease with the breast). For the nodular cancers are characterized by the node using a diameter all the way to several centimeters. In certain instances, a decent knot, is permeated with whitish layers tissue penetrating into the surrounding dimply skin, in others - a soft, juicy about 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 and forms about the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads over the surface of the breast and all sorts of the iron is roofed using a dense shell.

In histological structure include the following forms 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 examples of tissue and cell irregularities, which permitted to distinguish different level of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which will has the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes inside body: the entry into menopause, when there is an energetic restructuring from the hormonal regulation from the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, your body is going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most understanding of these changes, the breast tissue starts to dissolve and become replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role within the progression of cancer of the breast. The excess hormones inside the body results in a favorable background for developing the illness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (greater than one year) to cut back the risk of developing breast cancers. On the other hand, abortion cause hormonal "explosion" inside a woman's body that can trigger the progression of tumors. So far there is no consensus concerning the impact for the progression of tumors of hormonal contraceptive drugs, yet it's belief that these drugs reduce the chance of developing breast cancer, but increase the risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancers may cause harmful environmental factors: the planet, as well as inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to result in cancer, but simultaneously, create an unfavorable background for its development.

The cause of cancer of the breast may be the outcomes of radiation, like 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 lead to cancer from the breast and female the reproductive system, with an excess dimply skin inside body, it will become a different 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 in the growth of cancer of the breast:

- Nodular form, the most frequent, is seen as a dense knot of 0.5 to cm or higher, it's seen as an all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" of the breast and skin. For the first two forms are characteristic indications of inflammation: pain of the breast, a bright red color with the skin it raises temperature to 39 degrees C. In view of the symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, which are named and therefore are referred to these forms breast cancers. When tubular carcinoma breast cancer cover like a "skin" of its contracting and decreasing in dimensions.

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

For small tumors in the breast, any symptoms arise. The most observant women and their husbands are able to detect tumor site in the gland by accident, but in the large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a strong knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, can be firmly fixed for the surrounding tissue or skin, usually painless, can reach a substantial size (a lot more than 3 to 5 cm and infrequently 10-15 cm).

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