Breast Cancer

Among all cancers ladies, he takes the first place. In most cases, breast cancer 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, as well as cancer from the nipple along with the nipple in the field (Paget's disease in the breast). For the nodular cancers are characterized by the node developing a diameter as high as several centimeters. In certain instances, a good knot, is permeated with whitish layers tissue penetrating in to the surrounding dimply skin, in others - a soft, juicy on the cut, splits easily. Diffuse prostate type of cancer is covered for 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 some cases, the tumor spreads down the surface of the breast and many types of the iron is covered which has a dense shell.

In histological structure include the following types of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying levels 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 will gets the structure of scirrhus, and also 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 energetic restructuring in the hormonal regulation of the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, your body is going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most understanding of these changes, the breast tissue starts to dissolve and turn into replaced by fat.

Scientifically established that the female hormones estrogen-, plays a vital role inside growth and development of breast cancers. The excess hormones within the body results in a favorable background for developing the sickness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (over 12 months) to cut back potential risk of developing breast cancer. On the other hand, abortion bring about hormonal "explosion" in the woman's body that can trigger the continuing development of tumors. So far there's no consensus in regards to the impact around the continuing development of tumors of hormonal contraceptive drugs, yet it's thought that these drugs reduce the potential risk of developing breast cancers, but increase the potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast can cause harmful environmental factors: environmental surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a group of first-degree relatives with cancer of the breast (mothers and sisters) likelihood of having a tumor increasing by more than half - familial varieties of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to lead to cancer, but as well, create an unfavorable background for the development.

The reason behind breast cancer could be the effects of 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 result in cancer from the breast and female reproductive :, with an excess fatty tissue inside the body, it will become another endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are several forms from the growth of breast cancer:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" of the breast and skin. For the first 2 forms are characteristic warning signs of inflammation: pain from the breast, a bright red colorization of the skin it raises body 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 therefore are referred to these forms cancer of the breast. When tubular carcinoma breast cancer cover being a "skin" of its contracting and decreasing in size.

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

For small tumors from the breast, any symptoms arise. The most observant females and their husbands can easily detect tumor site inside the gland by accident, 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 strong knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, may be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a substantial size (over three to five cm and often 10-15 cm).

Need to gauge the surface with the skin in the tumor: the malignant process will probably be observed retraction of the skin, buying inside the folds, wrinkles, a signal of "lemon peel" - an area swelling with the skin within the tumor, is often a direct tumor invasion to the skin surface, then it is a bright red colorization and sprawl as "cauliflower."
