Breast Cancer

Among all cancers ladies, he takes the ultimate 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, along with cancer from the nipple and the nipple of the field (Paget's disease of the breast). For the nodular cancers are seen as the node using a diameter as high as several centimeters. In some instances, a decent knot, is permeated with whitish layers tissue penetrating in the surrounding fat, in others - a soft, juicy about the cut, splits easily. Diffuse prostate type of cancer is covered to get a considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads down the surface with the breast and many types of the iron is included having a dense shell.

In histological structure include the following kinds of breast cancers:

• 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 an varying levels of tissue and cell irregularities, which allowed to distinguish different a higher level malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which in turn gets the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The causes of breast cancers often are hormonal changes within the body: the entry into menopause, when there is an energetic restructuring with the hormonal regulation with the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, the body goes through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most responsive to these changes, the breast growth begins to dissolve and stay replaced by fat.

Scientifically established the female hormones estrogen-, plays a key role within the development of breast cancers. The excess hormones within the body generates a favorable background for developing the sickness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (greater than twelve months) to reduce potential risk of developing breast cancers. On the other hand, abortion result in hormonal "explosion" in a very woman's body that can trigger the progression of tumors. So far there is no consensus regarding the impact around the continuing development of tumors of hormonal contraceptive drugs, but it's belief that these drugs reduce the chance of developing cancer of the breast, but increase potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: the environment, and also inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to cause cancer, but simultaneously, create an unfavorable background because of its development.

The reason for cancer of the breast 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 result in cancer with the breast and female the reproductive system, having an excess fatty tissue inside the body, it is a different endocrine organ and starts 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 frequent, is seen as an a dense knot of 0.5 to cm or maybe more, it really is seen as an all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" with the breast and skin. For the first two forms are characteristic signs of inflammation: pain with the breast, a bright beautiful red colors with the skin it raises body temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, which are named and so are referred to these forms breast cancer. When tubular carcinoma breast cancers cover as a "skin" of the company's contracting and decreasing in proportions.

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

For small tumors of the breast, any symptoms arise. The most observant as well as their husbands can easily detect tumor site inside the gland unintentionally, but inside a large breast to detect small size hard knot. Revealed a knot can be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, can be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a significant size (more than 3 - 5 cm and often 10-15 cm).

Need to evaluate the surface in the skin within the tumor: the malignant process will likely be observed retraction of the skin, buying inside the folds, wrinkles, a symptom of "lemon peel" - a nearby swelling with the skin over the tumor, might be a direct tumor invasion to skin surface, then it becomes a bright red colorization and sprawl as "cauliflower."
