Breast Cancer

Among all cancers in females, he takes consumers. 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 in 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 creating a diameter as high as several centimeters. In some cases, a good knot, is permeated with whitish layers tissue penetrating in to the surrounding fatty tissue, in others - a soft, juicy on 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 your skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads down the surface from the breast and many types of the iron is covered using a dense shell.

In histological structure are the following forms of cancer of the breast:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers could be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is seen as an varying degrees of tissue and cell irregularities, which permitted to distinguish different amount of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which often contains the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The reasons for cancer of the breast often are hormonal changes in the body: the entry into menopause, if you find an active restructuring from the hormonal regulation from the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, the body is going through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most understanding of these changes, the breast tissue starts to dissolve and be replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role inside the development of breast cancer. The excess hormones within the body produces a favorable background for developing the sickness. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (more than 12 months) to cut back the chance of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" in the woman's body that may trigger the progression of tumors. So far there isn't any consensus concerning the impact about the growth and development of tumors of hormonal contraceptive drugs, yet it's belief that these drugs reduce the risk of developing cancer of the breast, but increase the potential risk of developing cancer from 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 category of first-degree relatives with breast cancers (mothers and sisters) chance of making a tumor increasing by greater than half - familial forms of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't cause cancer, but simultaneously, create an unfavorable background for its development.

The reason behind breast cancers may be the connection between radiation, including 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 in the breast and female the reproductive system, with the excess dimply skin inside body, it is another endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are a couple of forms with the growth of breast cancers:

- Nodular form, the most frequent, is seen as a dense knot of 0.5 to cm or more, it really is characterized by all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" in the breast and skin. For the first 2 forms are characteristic signs and symptoms of inflammation: pain of the breast, a bright red colorization of 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 are named and are described these forms cancer of the breast. When tubular carcinoma cancer of the breast cover like a "skin" of their contracting and decreasing in size.

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

For small tumors in the breast, any symptoms arise. The most observant women and their husbands can detect tumor site in the gland unintentionally, 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 and only a benign tumor. Signs of malignancy other: a strong knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, can be firmly fixed on the surrounding tissue or skin, usually painless, can reach a substantial size (over 3 - 5 cm and quite often 10-15 cm).

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