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, in addition to cancer in the nipple and also the nipple with the field (Paget's disease in the breast). For the nodular cancers are seen as the node creating a diameter all the way to several centimeters. In certain cases, a decent knot, is permeated with whitish layers tissue penetrating into the surrounding dimply skin, in others - a soft, juicy around the cut, splits easily. Diffuse prostate type of cancer is covered to get a considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads across the surface of the breast and many types of the iron is roofed having a dense shell.

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

• 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 a higher level malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which often gets the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancers often are hormonal changes in the body: the entry into menopause, if you have an energetic restructuring of the hormonal regulation from the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, our bodies is going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most attentive to these changes, the breast type tissue begins to dissolve and become replaced by fat.

Scientifically established the female hormones estrogen-, plays an important role within the progression of breast cancer. The excess hormones in the body creates a favorable background for developing the illness. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (over 1 year) to lessen the risk of developing cancer of the breast. On the other hand, abortion bring about hormonal "explosion" in a very woman's body that will trigger the growth and development of tumors. So far there isn't any consensus concerning the impact around the continuing development of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce potential risk of developing cancer of the breast, but increase the risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a family of first-degree relatives with cancer of the breast (mothers and sisters) chance of developing a tumor increasing by more than half - familial varieties of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not cause cancer, but as well, create an unfavorable background because of its development.

The reason behind cancer of the breast will be the outcomes of radiation, including 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 with the breast and female reproductive :, with the excess fat inside the body, it might be an outside endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are many forms with the growth of breast cancers:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" from the breast and skin. For the first couple of forms are characteristic warning signs of inflammation: pain with the breast, a bright red color from the skin it raises body's temperature to 39 degrees C. In view of such 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 cancer. When tubular carcinoma breast cancer cover as a "skin" of its contracting and decreasing in size.

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

For small tumors of the breast, any symptoms arise. The most observant ladies and their husbands can detect tumor site in the gland accidentally, but inside a large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks for a benign tumor. Signs of malignancy other: a strong knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, might be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a significant size (greater than 3 to 5 cm and infrequently 10-15 cm).

Need to gauge the surface in the skin over the tumor: the malignant process will be observed retraction in the skin, collecting inside folds, wrinkles, a symptom of "lemon peel" - a nearby swelling from the skin over the tumor, may be a direct tumor invasion to skin surface, then it is a bright red color and sprawl as "cauliflower."
