Breast Cancer

Among all cancers ladies, he takes consumers. 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, as well as cancer from the nipple along with the nipple with the field (Paget's disease in the breast). For the nodular cancers are seen as a the node having a diameter up to several centimeters. In certain cases, a good knot, is permeated with whitish layers tissue penetrating into the surrounding dimply skin, on other occasions - a soft, juicy about the cut, splits easily. Diffuse cancer of the prostate is roofed for a considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades your skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads down the surface in the breast and many types of the iron is included with a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as a varying degrees of tissue and cell irregularities, which allowed to distinguish different level of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which often gets the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The reasons behind cancer of the breast often are hormonal changes inside body: the entry into menopause, if you find an engaged restructuring of the hormonal regulation in the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, one's body will go through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most tuned in to these changes, the breast type tissue actually starts to dissolve and turn into replaced by fat.

Scientifically established that this female hormones estrogen-, plays a key role inside progression of breast cancer. The excess hormones within the body results in a favorable background for developing the sickness. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (a lot more than one year) to reduce potential risk of developing breast cancers. On the other hand, abortion cause hormonal "explosion" in a woman's body that may trigger the development of tumors. So far there isn't any consensus concerning the impact for the growth and development of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce potential risk of developing breast cancer, but increase the potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast may cause harmful environmental factors: the surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a group of first-degree relatives with breast cancer (mothers and sisters) risk of developing a tumor increasing by over half - familial forms of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to result in cancer, but at the same time, create an unfavorable background for the development.

The cause of cancer of the breast would 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 reproductive system, with the excess fatty tissue within the body, it is an outside endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are many forms from the growth of breast cancer:

- Nodular form, the commonest, is seen as a a dense knot of 0.5 to cm or more, it's characterized by all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" from the breast and skin. For the first couple of forms are characteristic signs and symptoms of inflammation: pain from the breast, a bright red colorization with the skin it raises body's temperature to 39 degrees C. In view of these symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, which can be named and so are known these forms cancer of the breast. When tubular carcinoma breast cancers cover like a "skin" of the company's contracting and decreasing in size.

In certain instances, breast cancer manifests in the form of metastases within the lymph nodes for the affected side, often does not detect the tumor itself - show hidden cancer of the breast.

For small tumors of the breast, any symptoms arise. The most observant women and their husbands have the ability to detect tumor site inside the gland accidentally, but in a very large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks for a benign tumor. Signs of malignancy other: a good 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 significant size (greater than 3 - 5 cm and sometimes 10-15 cm).

Need to evaluate the surface with the skin within the tumor: the malignant process will probably be observed retraction from the skin, obtaining inside the folds, wrinkles, an indication of "lemon peel" - a local swelling with the skin over the tumor, may be a direct tumor invasion to your skin surface, then it will become a bright beautiful red colors and sprawl as "cauliflower."
