Breast Cancer

Among all cancers in ladies, he takes the ultimate place. In most cases, breast cancers develops inside 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 and the nipple of the field (Paget's disease in the breast). For the nodular cancers are characterized by the node having a diameter all the way to several centimeters. In certain instances, a tight 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 cancer of prostate is covered 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 some cases, the tumor spreads down the surface from the breast and many types of the iron is roofed which has a dense shell.

In histological structure will be the following varieties of cancer of the breast:

• 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 varying levels of tissue and cell irregularities, which permitted to distinguish different level of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which will gets the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancer often are hormonal changes in the body: the entry into menopause, should there be a dynamic restructuring of the hormonal regulation in the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, the body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most understanding of these changes, the breast growth begins to dissolve and be replaced by fat.

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

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't bring about cancer, but at the same time, create an unfavorable background due to the development.

The reason for breast cancers could be the connection between radiation, such as 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 lead to cancer in the breast and female reproductive system, with an excess fat within the body, it might be another endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are many forms in the growth of breast cancer:

- Nodular form, the most typical, is seen as an a dense knot of 0.5 to five cm or maybe more, it's seen as an all of 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 couple of forms are characteristic indications of inflammation: pain with the breast, a bright red colorization with 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, which are named and so are known as these forms cancer of the breast. When tubular carcinoma breast cancer cover as being a "skin" of the contracting and decreasing in proportions.

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

For small tumors in the breast, any symptoms arise. The most observant women and their husbands can easily detect tumor site inside the gland by chance, 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 decent knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, may be firmly fixed to the surrounding tissue or skin, usually painless, can reach an important size (over 3 to 5 cm and infrequently 10-15 cm).

Need to evaluate the surface in the skin in the tumor: the malignant process will probably be observed retraction of the skin, obtaining within the folds, wrinkles, a signal of "lemon peel" - a local swelling from the skin in the tumor, might be a direct tumor invasion to your skin surface, then it will become a bright red colorization and sprawl as "cauliflower."
