Breast Cancer

Among all cancers in females, he takes the ultimate place. In most cases, breast cancer develops in the 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 along with the nipple from the field (Paget's disease in the breast). For the nodular cancers are characterized by the node using a diameter of up to several centimeters. In some cases, a good knot, is permeated with whitish layers tissue penetrating into the surrounding fatty tissue, on other occasions - a soft, juicy around the cut, splits easily. Diffuse cancer of prostate is included to get a considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades your skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads down the surface in the breast and many types of the iron is included which has a dense shell.

In histological structure would be the following types of cancer of the breast:

• 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 an varying examples of tissue and cell irregularities, which in a position to distinguish different a higher level malignancy. This type of cancer include, specifically, 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 breast cancers often are hormonal changes within the body: the entry into menopause, if you have a dynamic restructuring of the hormonal regulation from the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, the body will go through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most tuned in to these changes, the breast tissue actually starts to dissolve and stay replaced by fat.

Scientifically established that this female hormones estrogen-, plays an integral role inside continuing development of cancer of the breast. The excess hormones in the body creates 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 (a lot more than 1 year) to cut back the chance of developing breast cancer. On the other hand, abortion bring about hormonal "explosion" inside a woman's body that can trigger the growth and development of tumors. So far there's no consensus concerning the impact around the continuing development of tumors of hormonal contraceptive drugs, but it's believed that these drugs reduce the chance of developing breast cancers, but increase the chance of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: environmental surroundings, along with inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not lead to cancer, but simultaneously, create an unfavorable background for its development.

The reason for cancer of the breast will be the effects of radiation, like 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 cause cancer with the breast and female the reproductive system, by having an excess dimply skin within the body, it will become a separate endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are several forms from the growth of breast cancers:

- Nodular form, the most typical, is seen as a a dense knot of 0.5 to five cm or maybe more, it can be seen as all in 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 couple of forms are characteristic indications of inflammation: pain from the breast, a bright red color of the skin it raises body temperature to 39 degrees C. In view of these symptoms often occur, and errors in carried out patients treated for inflammatory diseases, which are named and therefore are referred to these forms breast cancer. When tubular carcinoma breast cancers cover being a "skin" of its contracting and decreasing in dimensions.

In certain instances, breast cancers manifests within the form of metastases within the lymph nodes on the affected side, often ceases to detect the tumor itself - show hidden cancer of the breast.

For small tumors of the breast, any symptoms arise. The most observant women and their husbands can easily detect tumor site in the gland by accident, but inside a 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 decent 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 tremendous size (over 3 - 5 cm and often 10-15 cm).

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