Breast Cancer

Among all cancers in females, he takes the ultimate place. In most cases, cancer of the breast 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 in the field (Paget's disease of the breast). For the nodular cancers are characterized by the node using a diameter of up to several centimeters. In some cases, a good knot, is permeated with whitish layers tissue penetrating in the surrounding dimply skin, on other occasions - a soft, juicy on the cut, splits easily. Diffuse prostate cancer is included for the considerable distance, the contours in 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 across the surface from the breast and the iron is included with a dense shell.

In histological structure are the following forms of breast cancers:

• 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 permitted to distinguish different amount of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which will has got the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes within the body: the entry into menopause, should there be an active restructuring in the hormonal regulation from the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, your body goes through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most attentive to these changes, the breast growth begins to dissolve and become replaced by fat.

Scientifically established how the female hormones estrogen-, plays an integral role within the continuing development of breast cancer. The excess hormones inside the body generates a favorable background for developing the condition. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (a lot more than 12 months) to reduce the chance of developing cancer of the breast. On the other hand, abortion lead to hormonal "explosion" in a very woman's body that can trigger the progression of tumors. So far there is absolutely no consensus in regards to the impact for the development of tumors of hormonal contraceptive drugs, but it is considered that these drugs reduce the risk of developing breast cancer, but increase the risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancer can cause harmful environmental factors: the surroundings, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a category of first-degree relatives with breast cancers (mothers and sisters) likelihood of creating a tumor increasing by more than half - familial types of cancer.

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

The cause of breast cancers would be the results of radiation, including irradiation in 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 with the breast and female reproductive system, having an excess dimply skin in the body, it might be another endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are several forms from the growth of breast cancers:

- Nodular form, the most common, is seen as a a dense knot of 0.5 to cm or higher, it is seen as a 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 2 forms are characteristic indications of inflammation: pain in the breast, a bright red colorization in the skin it raises body's temperature to 39 degrees C. In view of the symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, that happen to be named and they are described these forms breast cancers. When tubular carcinoma breast cancer cover being a "skin" of their contracting and decreasing in space.

In certain cases, breast cancer manifests inside the form of metastases in the lymph nodes about the affected side, often ceases to detect the tumor itself - show hidden breast cancer.

For small tumors with the breast, any symptoms arise. The most observant women and their husbands can easily detect tumor site inside gland by chance, but in the large breast to detect small size hard knot. Revealed a knot may be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach a tremendous size (more than three to five cm and infrequently 10-15 cm).

Need to gauge the surface with the skin within the tumor: the malignant process will be observed retraction with the skin, collecting inside folds, wrinkles, a symptom of "lemon peel" - a neighborhood swelling of the skin in the tumor, may be a direct tumor invasion to your skin surface, then it becomes a bright beautiful red colors and sprawl as "cauliflower."
