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, and also cancer in the nipple along with the nipple from the field (Paget's disease in the breast). For the nodular cancers are seen as the node having a diameter up to several centimeters. In certain cases, a tight knot, is permeated with whitish layers tissue penetrating to the surrounding fatty tissue, in other people - a soft, juicy around the cut, splits easily. Diffuse prostate cancer is included for any considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades your skin layer and forms on the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads down the surface of the breast and all the iron is roofed with a dense shell.

In histological structure include the following varieties of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive cancer of the breast may be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is characterized by 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 usually has the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The reasons for breast cancers often are hormonal changes within the body: the entry into menopause, when there is an engaged restructuring with the hormonal regulation from the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, your body is going through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most responsive to these changes, the breast tissue begins to dissolve and turn into replaced by fat.

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

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not result in cancer, but concurrently, create an unfavorable background because of its development.

The reason behind cancer of the breast may be the effects of radiation, for example 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 cause cancer in the breast and female the reproductive system, having an excess fat within the body, it is a different 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 in the growth of cancer of the breast:

- Nodular form, the most typical, is characterized by a dense knot of 0.5 to cm or maybe more, it can be seen as a all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" in the breast and skin. For the initial two forms are characteristic signs of inflammation: pain with the breast, a bright red color in the skin it raises body's temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that happen to be named and they are known these forms cancer of the breast. When tubular carcinoma breast cancers cover like a "skin" of its contracting and decreasing in proportions.

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

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

Need to assess the surface of the skin on the tumor: the malignant process is going to be observed retraction in the skin, obtaining inside folds, wrinkles, an indicator of "lemon peel" - a nearby swelling with the skin on the tumor, can be a direct tumor invasion to skin surface, then it becomes a bright red color and sprawl as "cauliflower."
