Breast Cancer

Among all cancers in females, he takes consumers. In most cases, cancer of the breast 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, in addition to cancer of the nipple and the nipple in the field (Paget's disease in the breast). For the nodular cancers are seen as an the node creating a diameter all the way to several centimeters. In some instances, a strong knot, is permeated with whitish layers tissue penetrating into the surrounding fat, in others - a soft, juicy around the cut, splits easily. Diffuse prostate cancer is included to get a considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades the skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads over the surface of the breast and all sorts of the iron is included using a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying degrees 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 often has the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancer often are hormonal changes inside body: the entry into menopause, when there is an energetic restructuring with the hormonal regulation of the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, your body is going through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most attentive to these changes, the breast growth actually starts to dissolve and stay replaced by fat.

Scientifically established that this female hormones estrogen-, plays an integral role within the development of cancer of the breast. The excess hormones within the body generates a favorable background for developing the sickness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (more than 1 year) to cut back the potential risk of developing breast cancer. On the other hand, abortion lead to hormonal "explosion" in the 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, but it is belief that these drugs reduce potential risk of developing breast cancers, but increase potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancer can cause harmful environmental factors: the environment, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has 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 usually do not cause cancer, but simultaneously, create an unfavorable background for the development.

The cause of breast cancer would be the connection between 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 :, by having an excess fat inside body, it might be a separate endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are some forms in the growth of cancer of the breast:

- Nodular form, the most common, is seen as a a dense knot of 0.5 to cm or higher, it is seen as all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" from the breast and skin. For the first 2 forms are characteristic signs and symptoms of inflammation: pain in the breast, a bright beautiful red colors in the skin it raises body temperature to 39 degrees C. In view of those symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, that happen to be named and they are known these forms breast cancers. When tubular carcinoma breast cancers cover like a "skin" of the contracting and decreasing in size.

In certain cases, breast cancers manifests in the form of metastases inside lymph nodes around the affected side, often does not detect the tumor itself - show hidden breast cancers.

For small tumors of the breast, any symptoms arise. The most observant women and their husbands are able to detect tumor site in the gland by accident, but inside a large breast to detect small size hard knot. Revealed a knot may 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 really is stationary or slightly shifted, could be firmly fixed on the surrounding tissue or skin, usually painless, can reach an important size (a lot more than 3 to 5 cm and often 10-15 cm).

Need to gauge the surface of the skin within the tumor: the malignant process is going to be observed retraction of the skin, collecting in the folds, wrinkles, an indication of "lemon peel" - a neighborhood swelling of the skin in the tumor, is often a direct tumor invasion to the skin surface, then it is a bright red colorization and sprawl as "cauliflower."
