Breast Cancer

Among all cancers in women, he takes the first place. In most cases, breast cancers 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, as well as cancer with the nipple and the nipple with the field (Paget's disease of the breast). For the nodular cancers are seen as an the node developing a diameter all the way to several centimeters. In some cases, a strong knot, is permeated with whitish layers tissue penetrating in to the surrounding fat, in other people - a soft, juicy around the cut, splits easily. Diffuse prostate cancer is included for the considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades skin and forms for the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads along the surface with the breast and all sorts of the iron is roofed having a dense shell.

In histological structure are the following kinds of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive cancer of the breast could 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 in a position to distinguish different level of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which often contains the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The reasons behind cancer of the breast often are hormonal changes within the body: the entry into menopause, if you have an active restructuring in the hormonal regulation in 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 from the uterus) are most understanding of these changes, the breast growth starts to dissolve and turn into replaced by fat.

Scientifically established how the female hormones estrogen-, plays a vital role in the continuing development of breast cancers. The excess hormones in the body produces a favorable background for developing the sickness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (a lot more than 12 months) to reduce the potential risk of developing breast cancer. On the other hand, abortion cause hormonal "explosion" in the woman's body that may trigger the development of tumors. So far there is no consensus about the impact about the development of tumors of hormonal contraceptive drugs, but it's thought that these drugs reduce the potential risk of developing breast cancers, but increase potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: the environment, and also inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't bring about cancer, but at the same time, create an unfavorable background for the development.

The source of cancer of the breast may be the connection between radiation, including irradiation of 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 in the breast and female the reproductive system, having an excess fatty tissue within the body, it is another endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are a couple of forms of the growth of cancer of the breast:

- Nodular form, the most typical, is seen as an a dense knot of 0.5 to cm or more, it's characterized by all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" with the breast and skin. For the first two forms are characteristic signs and symptoms of inflammation: pain of the breast, a bright red colorization with the skin it raises body's temperature to 39 degrees C. In view of the symptoms often occur, and errors in carried out patients treated for inflammatory diseases, which are named and they are described these forms cancer of the breast. When tubular carcinoma breast cancers cover like a "skin" of their contracting and decreasing in size.

In some instances, breast cancer manifests within the form of metastases inside the lymph nodes for the affected side, often doesn't detect the tumor itself - show hidden cancer of the breast.

For small tumors in the breast, any symptoms arise. The most observant as well as their husbands are able to detect tumor site inside the gland accidentally, 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 decent knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, can be firmly fixed on the surrounding tissue or skin, usually painless, can reach a substantial size (over 3 - 5 cm and often 10-15 cm).

Need to evaluate the surface from the skin over the tumor: the malignant process is going to be observed retraction in the skin, obtaining in the folds, wrinkles, an indicator of "lemon peel" - an area swelling in the skin over the tumor, might be a direct tumor invasion to the skin surface, then it will become a bright beautiful red colors and sprawl as "cauliflower."
