Breast Cancer

Among all cancers in ladies, he takes the initial 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, in addition to cancer with the nipple as well as the nipple with the field (Paget's disease from the breast). For the nodular cancers are characterized by the node having a diameter all the way to several centimeters. In some cases, a strong knot, is permeated with whitish layers tissue penetrating to the surrounding fatty tissue, in others - a soft, juicy about the cut, splits easily. Diffuse cancer of the prostate is included for any considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads over the surface from the breast and all sorts of the iron is included which has a dense shell.

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

• 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 a varying examples of tissue and cell irregularities, which able to distinguish different a higher level malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which usually contains the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The causes of cancer of the breast often are hormonal changes in the body: the entry into menopause, if you find a dynamic restructuring from the hormonal regulation of the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, your body will go through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most tuned in to these changes, the breast tissue begins to dissolve and be replaced by fat.

Scientifically established how the female hormones estrogen-, plays an important role within the progression of cancer of the breast. The excess hormones in the body produces a favorable background for developing the condition. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (more than 1 year) to lessen the potential risk of developing cancer of the breast. On the other hand, abortion lead to hormonal "explosion" in the woman's body that will trigger the progression of tumors. So far there's no consensus about the impact about the growth and development of tumors of hormonal contraceptive drugs, but it's believed that these drugs reduce the chance of developing breast cancer, but increase the risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast may cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

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

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

The cause of breast cancer may be the outcomes 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 lead to cancer from the breast and female reproductive :, having an excess fat in the body, it might be 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 some forms with the growth of breast cancer:

- Nodular form, the most typical, is seen as a dense knot of 0.5 to 5 cm or more, it is characterized by all from 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 two forms are characteristic warning signs of inflammation: pain of the breast, a bright red colorization in the skin it raises temperature to 39 degrees C. In view of these symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, that happen to be named and therefore are referred to these forms cancer of the breast. When tubular carcinoma breast cancers cover like a "skin" of the contracting and decreasing in dimensions.

In some instances, breast cancers manifests inside the form of metastases inside the lymph nodes around the affected side, often does not detect the tumor itself - show hidden cancer of the breast.

For small tumors with the breast, any symptoms arise. The most observant females and their husbands are able to detect tumor site in the gland accidentally, but in a very large breast to detect small size hard knot. Revealed a knot may be painful when pressed, round, smooth and agile, this speaks in favor of a benign tumor. Signs of malignancy other: a strong knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, may be firmly fixed towards the surrounding tissue or skin, usually painless, can reach an important size (greater than 3 to 5 cm and often 10-15 cm).

Need to evaluate the surface of the skin over the tumor: the malignant process is going to be observed retraction from the skin, collecting in the folds, wrinkles, an indication of "lemon peel" - a nearby swelling from the skin on the tumor, can be a direct tumor invasion to your skin surface, then it becomes a bright red colorization and sprawl as "cauliflower."
