Breast Cancer

Among all cancers in ladies, he takes the first place. In most cases, cancer of the breast develops within 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 of the nipple as well as the nipple with the field (Paget's disease in the breast). For the nodular cancers are characterized by 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 fat, on other occasions - a soft, juicy for the cut, splits easily. Diffuse cancer of the prostate is included for a considerable distance, the contours of 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 along the surface in the breast and many types of the iron is covered with a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers 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 able to distinguish different level of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which often contains the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes within the body: the entry into menopause, should there be an active restructuring in the hormonal regulation with the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, your body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most understanding of these changes, the breast type tissue starts to dissolve and be replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role in the progression of breast cancer. The excess hormones inside the body produces a favorable background for developing the disease. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (over 1 year) to reduce the risk of developing breast cancers. On the other hand, abortion result in hormonal "explosion" in a very woman's body that may trigger the development of tumors. So far there is no consensus regarding the impact on the continuing development of tumors of hormonal contraceptive drugs, yet it's belief that these drugs reduce the potential risk of developing breast cancers, but increase potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancer can cause harmful environmental factors: environmental surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a category of first-degree relatives with breast cancer (mothers and sisters) chance of developing a tumor increasing by over half - familial forms of cancer.

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

The cause of breast cancer may be the connection between 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 bring about cancer from the breast and female the reproductive system, with the excess fatty tissue inside body, it becomes a different endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are a couple of forms in the growth of breast cancers:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" of the breast and skin. For the initial two forms are characteristic indications of inflammation: pain in the breast, a bright red colorization with the skin it raises body's temperature to 39 degrees C. In view of those symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, that happen to be named and are known as these forms cancer of the breast. When tubular carcinoma cancer of the breast cover as a "skin" of its contracting and decreasing in size.

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

For small tumors from the breast, any symptoms arise. The most observant women and their husbands are able to detect tumor site in the gland by accident, but in the large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks in favor of a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (more than 3 - 5 cm and quite often 10-15 cm).

Need to evaluate the surface with the skin over the tumor: the malignant process is going to be observed retraction from the skin, picking up inside the folds, wrinkles, a signal of "lemon peel" - a local swelling in the skin over the tumor, can be a direct tumor invasion to skin surface, then it might be a bright red colorization and sprawl as "cauliflower."
