Breast Cancer

Among all cancers ladies, he takes the ultimate place. In most cases, breast cancer develops in the presence of precancerous changes. This is primarily a benign mammary dysplasia and papilloma ducts.

Breast cancer is represented macroscopically nodular and diffuse forms, and also cancer from the nipple and also the nipple from the field (Paget's disease with the breast). For the nodular cancers are seen as the node developing a diameter all the way to several centimeters. In some instances, a tight knot, is permeated with whitish layers tissue penetrating into the surrounding fatty tissue, in other people - a soft, juicy about the cut, splits easily. Diffuse cancer of the prostate is covered for any considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads along the surface of the breast and the iron is included 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 seen as a varying degrees of tissue and cell irregularities, which allowed to distinguish different amount of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which in turn has got the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes inside body: the entry into menopause, when there is an engaged restructuring in the hormonal regulation from 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 in the uterus) are most understanding of these changes, the breast growth actually starts to dissolve and turn into replaced by fat.

Scientifically established the female hormones estrogen-, plays an integral role in the continuing development of breast cancer. The excess hormones inside the body creates a favorable background for developing the disease. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (over twelve months) to reduce potential 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 is absolutely no consensus about the impact about the progression of tumors of hormonal contraceptive drugs, but it's belief that these drugs reduce potential risk of developing cancer of the breast, but increase the potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancers could cause harmful environmental factors: environmental surroundings, along with inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not lead to cancer, but simultaneously, create an unfavorable background because of its development.

The reason behind breast cancer may be the connection between radiation, including irradiation with 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 an excess dimply skin inside body, it becomes a separate endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are many forms of the growth of cancer of the breast:

- Nodular form, the commonest, is characterized by a dense knot of 0.5 to cm or even more, it really is 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" from the breast and skin. For the first two forms are characteristic warning signs of inflammation: pain of the breast, a bright red colorization in the skin it raises body temperature to 39 degrees C. In view of those symptoms often occur, and errors in carried out patients treated for inflammatory diseases, that happen to be named and they are known these forms cancer of the breast. When tubular carcinoma cancer of the breast cover like a "skin" of their contracting and decreasing in space.

In certain instances, cancer of the breast manifests inside the form of metastases within the lymph nodes around the affected side, often fails to detect the tumor itself - show hidden cancer of the breast.

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

Need to assess the surface with the skin over the tumor: the malignant process is going to be observed retraction in the skin, buying inside folds, wrinkles, an indicator of "lemon peel" - an area swelling of the skin within the tumor, might be a direct tumor invasion to skin surface, then it might be a bright red colorization and sprawl as "cauliflower."
