Breast Cancer

Among all cancers in ladies, he takes the initial place. In most cases, breast cancer develops inside presence of precancerous changes. This is primarily a benign mammary dysplasia and papilloma ducts.

Breast cancer is represented macroscopically nodular and diffuse forms, in addition to cancer in the nipple and the nipple with the field (Paget's disease with the breast). For the nodular cancers are seen as a the node having a diameter as high as several centimeters. In certain instances, a strong knot, is permeated with whitish layers tissue penetrating to the surrounding dimply skin, on other occasions - a soft, juicy on the cut, splits easily. Diffuse cancer of prostate is covered for the considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades the skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads over the surface from the breast and the iron is roofed having a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as a varying levels of tissue and cell irregularities, which allowed to distinguish different a higher level malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which will has the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The causes of breast cancers often are hormonal changes in the body: the entry into menopause, if you find an engaged restructuring of the hormonal regulation with the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, your body will go through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most understanding of these changes, the breast type tissue actually starts to dissolve and become replaced by fat.

Scientifically established that the female hormones estrogen-, plays an integral role in the continuing development of cancer of the breast. The excess hormones inside 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 how the birth and prolonged breastfeeding (a lot more than 1 year) to relieve the chance of developing cancer of the breast. On the other hand, abortion bring about hormonal "explosion" in a woman's body that could trigger the growth and development of tumors. So far there is absolutely no consensus concerning the impact for the development of tumors of hormonal contraceptive drugs, but it's belief that these drugs reduce the risk of developing breast cancers, but increase potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancers may cause harmful environmental factors: the surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients having a family of first-degree relatives with cancer of the breast (mothers and sisters) risk of creating a tumor increasing by greater than half - familial types of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't result in cancer, but simultaneously, create an unfavorable background because of its development.

The reason for breast cancers could be the results of radiation, for example irradiation from 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 of the breast and female the reproductive system, with an excess dimply skin inside the body, it might be another endocrine organ and actually starts 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 breast cancers:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" from the breast and skin. For the first two forms are characteristic signs of inflammation: pain in 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 proper diagnosis of patients treated for inflammatory diseases, that are named and so are referred to these forms cancer of the breast. When tubular carcinoma breast cancers cover as being a "skin" of the company's contracting and decreasing in dimensions.

In certain instances, cancer of the breast 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 in the breast, any symptoms arise. The most observant ladies and their husbands are able to detect tumor site inside gland unintentionally, 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 for a benign tumor. Signs of malignancy other: a tight knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, might be firmly fixed for the surrounding tissue or skin, usually painless, can reach a substantial size (over 3 to 5 cm and often 10-15 cm).

Need to gauge the surface of the skin on the tumor: the malignant process will be observed retraction with the skin, obtaining inside the folds, wrinkles, a symptom of "lemon peel" - a neighborhood swelling with the skin on the tumor, may be a direct tumor invasion to your skin layer surface, then it will become a bright beautiful red colors and sprawl as "cauliflower."
