Breast Cancer

Among all cancers ladies, he takes the ultimate place. In most cases, breast cancer develops inside 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 in the nipple and also the nipple with the field (Paget's disease of the breast). For the nodular cancers are seen as an the node having a diameter all the way to several centimeters. In some cases, a good knot, is permeated with whitish layers tissue penetrating in to the surrounding fatty tissue, in other people - a soft, juicy around the cut, splits easily. Diffuse cancer of the prostate is covered for any considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades your skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads over the surface of the breast and the iron is covered using a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as a varying examples 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 often contains the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The reasons for cancer of the breast often are hormonal changes in the body: the entry into menopause, if you find an energetic restructuring of the hormonal regulation of the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, one's body goes through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most understanding of these changes, the breast growth actually starts to dissolve and stay replaced by fat.

Scientifically established that this female hormones estrogen-, plays a vital role in the growth and development of breast cancer. The excess hormones within the body produces a favorable background for developing the disease. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (more than one year) to reduce the potential risk of developing cancer of the breast. On the other hand, abortion lead to hormonal "explosion" in the woman's body that could trigger the continuing development of tumors. So far there's no consensus about the impact around the development of tumors of hormonal contraceptive drugs, yet it's considered that these drugs reduce potential risk of developing cancer of the breast, but increase the chance of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancers can cause harmful environmental factors: the planet, as well as inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't lead to cancer, but simultaneously, create an unfavorable background due to the development.

The reason for breast cancer may be the results 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 bring about cancer of the breast and female reproductive system, having an excess fatty tissue inside the body, it becomes 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 a couple of forms of the growth of breast cancer:

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

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

In certain instances, breast cancer manifests inside the form of metastases inside lymph nodes on the affected side, often does not 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 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 and only a benign tumor. Signs of malignancy other: a tight knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, might be firmly fixed for the surrounding tissue or skin, usually painless, can reach a tremendous size (a lot more than 3 to 5 cm and often 10-15 cm).

Need to gauge the surface from the skin over the tumor: the malignant process will probably be observed retraction from the skin, buying within the folds, wrinkles, an indication of "lemon peel" - an area swelling of the skin on the tumor, may be a direct tumor invasion to the skin surface, then it becomes a bright red color and sprawl as "cauliflower."
