Breast Cancer

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

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

• 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 characterized by varying examples of tissue and cell irregularities, which in a position to distinguish different amount 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 for breast cancers often are hormonal changes inside body: the entry into menopause, when there is an active restructuring from the hormonal regulation from the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, the body is going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most responsive to these changes, the breast growth actually starts to dissolve and turn into replaced by fat.

Scientifically established the female hormones estrogen-, plays an important role inside growth and development of breast cancer. The excess hormones inside body creates 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 (more than 1 year) to lessen potential risk of developing breast cancers. On the other hand, abortion result in hormonal "explosion" in the woman's body that may trigger the development of tumors. So far there is no consensus concerning the impact about the continuing development of tumors of hormonal contraceptive drugs, yet it's believed that these drugs reduce the chance of developing breast cancers, but increase the risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: the planet, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients having a family of first-degree relatives with cancer of the breast (mothers and sisters) probability of having a tumor increasing by over half - familial types of cancer.

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

The reason for cancer of the breast could be the results of radiation, such as 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 result in cancer of the breast and female the reproductive system, with an excess fat inside the body, it is a separate 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 a couple of forms from the growth of cancer of the breast:

- Nodular form, the most typical, is seen as an a dense knot of 0.5 to 5 cm or higher, it is seen as all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" of the breast and skin. For the first couple of forms are characteristic signs and symptoms of inflammation: pain with the breast, a bright red colorization with the skin it raises temperature to 39 degrees C. In view of those symptoms often occur, and errors in carried out patients treated for inflammatory diseases, which are named and therefore are described these forms cancer of the breast. When tubular carcinoma breast cancers cover being a "skin" of the contracting and decreasing in size.

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

For small tumors from the breast, any symptoms arise. The most observant ladies and their husbands have the ability to detect tumor site inside gland unintentionally, but in a large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks in support of 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, can be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (more than 3 - 5 cm and infrequently 10-15 cm).

Need to gauge the surface of the skin on the tumor: the malignant process is going to be observed retraction of the skin, collecting within the folds, wrinkles, an indicator of "lemon peel" - an area swelling from the skin over the tumor, is often a direct tumor invasion to skin surface, then it will become a bright beautiful red colors and sprawl as "cauliflower."
