Breast Cancer

Among all cancers in women, he takes the first place. In most cases, breast cancers 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, and also cancer from the nipple as well as the nipple from the field (Paget's disease from the breast). For the nodular cancers are seen as a the node developing a diameter all the way to several centimeters. In some instances, a strong knot, is permeated with whitish layers tissue penetrating in the surrounding fatty tissue, in other people - a soft, juicy about the cut, splits easily. Diffuse prostate cancer is included to get a considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades your skin layer and forms around the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads down the surface with the breast and many types of the iron is roofed using a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancer 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 able to distinguish different degree of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which often has got the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancers often are hormonal changes inside body: the entry into menopause, if you find an energetic restructuring in the hormonal regulation with the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, your body goes through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most attentive to these changes, the breast growth begins to dissolve and become replaced by fat.

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

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

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to result in cancer, but concurrently, create an unfavorable background because of its development.

The reason for breast cancer may be the effects of radiation, such as irradiation of 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 result in cancer of the breast and female the reproductive system, by having an excess fat within the body, it becomes another endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are several forms from the growth of breast cancer:

- Nodular form, the most typical, is seen as an a dense knot of 0.5 to five cm or higher, it can be seen as an all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" of the breast and skin. For the first 2 forms are characteristic signs and symptoms of inflammation: pain with 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, that are named and are known as these forms cancer of the breast. When tubular carcinoma cancer of the breast cover as being a "skin" of the company's contracting and decreasing in dimensions.

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

For small tumors with the breast, any symptoms arise. The most observant ladies and their husbands can detect tumor site within 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, may be firmly fixed to the surrounding tissue or skin, usually painless, can reach an important size (a lot more than three to five cm and infrequently 10-15 cm).

Need to assess the surface of the skin over the tumor: the malignant process will likely be observed retraction with the skin, collecting inside the folds, wrinkles, an indicator of "lemon peel" - an area swelling from the skin within the tumor, might be a direct tumor invasion to skin surface, then it is a bright red colorization and sprawl as "cauliflower."
