Breast Cancer

Among all cancers ladies, he takes the first place. In most cases, breast cancers develops inside 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 from the nipple and the nipple with 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 some cases, 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 prostate type of cancer is roofed for a considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades your skin and forms for the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads down the surface with the breast and all sorts of the iron is covered having a dense shell.

In histological structure are the following forms of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancer could 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 permitted to distinguish different level of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which in turn gets the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The reasons behind cancer of the breast often are hormonal changes within the body: the entry into menopause, should there be an active restructuring in the hormonal regulation from the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, your body goes through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most attentive to these changes, the breast tissue actually starts to dissolve and turn into replaced by fat.

Scientifically established that the female hormones estrogen-, plays a key role inside progression of breast cancers. The excess hormones inside body generates a favorable background for developing the disease. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (over one year) to cut back potential risk of developing breast cancers. On the other hand, abortion result in hormonal "explosion" in a very woman's body that may trigger the continuing development of tumors. So far there isn't any consensus about the impact around the continuing development of tumors of hormonal contraceptive drugs, but it's thought that these drugs reduce potential risk of developing breast cancer, but increase potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast could cause harmful environmental factors: the environment, along with inflammatory diseases previously deferred breast - mastitis.

In addition, patients having a group of first-degree relatives with breast cancer (mothers and sisters) likelihood of making a tumor increasing by more than half - familial kinds of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not lead to cancer, but at the same time, create an unfavorable background because of its development.

The source of breast cancers will be the connection between radiation, like 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 the excess dimply skin inside the body, it might be an outside endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are many forms in the growth of breast cancers:

- Nodular form, the most common, is seen as a dense knot of 0.5 to five cm or even more, it is seen as an all with the following symptoms;

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

In some instances, breast cancers manifests in the form of metastases inside lymph nodes for the affected side, often ceases to detect the tumor itself - show hidden breast cancers.

For small tumors in the breast, any symptoms arise. The most observant ladies and their husbands have the ability to detect tumor site inside 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 in support of 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 to the surrounding tissue or skin, usually painless, can reach a significant size (more than 3 to 5 cm and often 10-15 cm).

Need to assess the surface in the skin over the tumor: the malignant process will be observed retraction in the skin, obtaining inside folds, wrinkles, an indication of "lemon peel" - a nearby swelling from the skin over the tumor, is often a direct tumor invasion to your skin surface, then it might be a bright beautiful red colors and sprawl as "cauliflower."
