Breast Cancer

Among all cancers in women, he takes consumers. 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, along with cancer with the nipple and also the nipple from the field (Paget's disease in the breast). For the nodular cancers are seen as a the node creating a diameter all the way to several centimeters. In some instances, a tight knot, is permeated with whitish layers tissue penetrating to the surrounding dimply skin, in others - a soft, juicy on the cut, splits easily. Diffuse prostate type of cancer is included for the considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades the skin and forms for the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads across the surface with the breast and the iron is included which has a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as an varying levels of tissue and cell irregularities, which able to distinguish different a higher level malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which in turn has got the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancer often are hormonal changes in the body: the entry into menopause, when there is an active restructuring in the hormonal regulation in the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, our bodies is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most tuned in to these changes, the breast tissue actually starts to dissolve and be replaced by fat.

Scientifically established how the female hormones estrogen-, plays a key role inside the growth and development of breast cancer. The excess hormones in the body generates a favorable background for developing the illness. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (greater than 12 months) to cut back potential risk of developing breast cancers. On the other hand, abortion cause hormonal "explosion" in a very woman's body that may trigger the development of tumors. So far there's no consensus in regards to the impact about the development of tumors of hormonal contraceptive drugs, however it is thought that these drugs reduce the potential risk of developing breast cancer, but increase the potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancers can cause harmful environmental factors: the environment, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a family of first-degree relatives with breast cancer (mothers and sisters) probability of making a tumor increasing by a lot more than half - familial kinds of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not lead to cancer, but as well, create an unfavorable background for its development.

The reason for cancer of the breast may 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 :, by having an excess dimply skin in the body, it is an outside endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are several forms of the growth of cancer of the breast:

- Nodular form, the most typical, is seen as a dense knot of 0.5 to five cm or more, it's 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" with the breast and skin. For the first couple of forms are characteristic signs of inflammation: pain in the breast, a bright red colorization in the skin it raises temperature to 39 degrees C. In view of these symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that are named and they are known these forms breast cancers. When tubular carcinoma breast cancer cover as being a "skin" of the company's contracting and decreasing in size.

In certain instances, cancer of the breast manifests inside form of metastases in the lymph nodes about the affected side, often does not 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 easily detect tumor site within the gland by chance, but inside a large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a tight knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, might be firmly fixed for the surrounding tissue or skin, usually painless, can reach a significant size (a lot more than 3 - 5 cm and often 10-15 cm).

Need to gauge the surface with the skin on the tumor: the malignant process will likely be observed retraction from the skin, obtaining in the folds, wrinkles, a signal of "lemon peel" - a nearby swelling from the skin in the tumor, might be a direct tumor invasion to skin surface, then it becomes a bright beautiful red colors and sprawl as "cauliflower."
