Breast Cancer

Among all cancers in women, he takes the ultimate place. In most cases, breast cancers 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, in addition to cancer from the nipple as well as the nipple of the field (Paget's disease in the breast). For the nodular cancers are seen as the node creating a diameter up to several centimeters. In certain cases, a decent knot, is permeated with whitish layers tissue penetrating in to the surrounding fat, on other occasions - a soft, juicy around the cut, splits easily. Diffuse cancer of the prostate is covered to get a considerable distance, the contours of 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 cases, the tumor spreads across the surface from the breast and all the iron is roofed having a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as an varying degrees of tissue and cell irregularities, which allowed to distinguish different a higher level malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which in turn has got the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes inside the body: the entry into menopause, if you have an engaged restructuring in the hormonal regulation in the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, our bodies will go 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 turn into replaced by fat.

Scientifically established that this female hormones estrogen-, plays a vital role inside the continuing development of breast cancer. The excess hormones inside 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 the birth and prolonged breastfeeding (a lot more than 12 months) to lessen the potential risk of developing cancer of the breast. On the other hand, abortion result in hormonal "explosion" in the woman's body that may trigger the development of tumors. So far there's no consensus in regards to the impact for the progression of tumors of hormonal contraceptive drugs, however it is believed that these drugs reduce the chance of developing breast cancers, but increase potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: the planet, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a category of first-degree relatives with cancer of the breast (mothers and sisters) risk of creating a tumor increasing by greater than half - familial kinds of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to lead to cancer, but concurrently, create an unfavorable background because of its development.

The reason for breast cancers will be the effects of radiation, such as 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 lead to cancer from the breast and female the reproductive system, by having an excess fat within the body, it is a different 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 in the growth of cancer of the breast:

- Nodular form, the most common, is seen as a a dense knot of 0.5 to 5 cm or higher, it's characterized by all from 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 first 2 forms are characteristic signs and symptoms of inflammation: pain with the breast, a bright red color with the skin it raises temperature to 39 degrees C. In view of those symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that are named and so are referred to these forms breast cancers. When tubular carcinoma breast cancers cover as being a "skin" of the company's contracting and decreasing in space.

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

For small tumors from the breast, any symptoms arise. The most observant women and their husbands are able to detect tumor site inside gland by accident, but in a large breast to detect small size hard knot. Revealed a knot can be painful when pressed, round, smooth and agile, this speaks for 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 substantial size (over 3 - 5 cm and infrequently 10-15 cm).

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