Breast Cancer

Among all cancers in ladies, 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, and also cancer of the nipple and the nipple with the field (Paget's disease in the breast). For the nodular cancers are seen as an the node using a diameter all the way to several centimeters. In some instances, a decent knot, is permeated with whitish layers tissue penetrating in to the surrounding fatty tissue, on other occasions - a soft, juicy on the cut, splits easily. Diffuse prostate cancer is included for the considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades your skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads over the surface from the breast and many types of the iron is included having a dense shell.

In histological structure are the following kinds of cancer of the breast:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Causes of Breast Cancer.

The reasons for breast cancer often are hormonal changes within the body: the entry into menopause, should there be an engaged restructuring with the hormonal regulation in the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, our bodies will go through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most tuned in to these changes, the breast type tissue begins to dissolve and stay replaced by fat.

Scientifically established that the female hormones estrogen-, plays a key role inside the continuing development of cancer of the breast. The excess hormones within the body produces a favorable background for developing the sickness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (over one year) to reduce the risk of developing cancer of the breast. On the other hand, abortion bring about hormonal "explosion" in a very woman's body that can trigger the development of tumors. So far there isn't any consensus about the impact around the growth and development of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce potential risk of developing cancer of the breast, but increase the risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancers could cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients having a category of first-degree relatives with cancer of the breast (mothers and sisters) chance of developing a tumor increasing by a lot more than half - familial forms of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not bring about cancer, but concurrently, create an unfavorable background for the development.

The source of breast cancers will be the outcomes of radiation, for example 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 lead to cancer with the breast and female reproductive :, having an excess dimply skin inside the body, it might be a different endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are several forms with the growth of cancer of the breast:

- Nodular form, the most common, is characterized by a dense knot of 0.5 to 5 cm or even more, it's seen as all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" in the breast and skin. For the first couple of forms are characteristic indications of inflammation: pain of the breast, a bright red color of the skin it raises temperature to 39 degrees C. In view of the symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, which are named and are described these forms cancer of the breast. When tubular carcinoma breast cancers cover as being a "skin" of its contracting and decreasing in proportions.

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

For small tumors with the breast, any symptoms arise. The most observant as well as their husbands can easily detect tumor site inside the gland by chance, but inside 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 really is stationary or slightly shifted, might be firmly fixed to the surrounding tissue or skin, usually painless, can reach an important size (more than 3 to 5 cm and infrequently 10-15 cm).

Need to gauge the surface of the skin over the tumor: the malignant process is going to be observed retraction of the skin, picking up inside the folds, wrinkles, an indicator of "lemon peel" - a nearby swelling from the skin on the tumor, might be a direct tumor invasion to your skin surface, then it becomes a bright beautiful red colors and sprawl as "cauliflower."
