Breast Cancer

Among all cancers in ladies, he takes the first place. In most cases, cancer of the breast 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 from the nipple along with the nipple of the field (Paget's disease in the breast). For the nodular cancers are seen as an the node having a diameter up to several centimeters. In certain instances, a tight knot, is permeated with whitish layers tissue penetrating into the surrounding dimply skin, on other occasions - a soft, juicy around the cut, splits easily. Diffuse cancer of the prostate is roofed for a considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades the skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads down the surface in the breast and many types of the iron is included having a dense shell.

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

• 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 examples 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 will has the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The factors behind cancer of the breast often are hormonal changes inside the body: the entry into menopause, when there is an energetic restructuring with 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 with the uterus) are most attentive to these changes, the breast type tissue begins to dissolve and become replaced by fat.

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

In addition, patients with a group of first-degree relatives with breast cancer (mothers and sisters) risk of making a tumor increasing by a lot more than half - familial kinds of cancer.

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

The reason behind breast cancers will be the connection between radiation, like 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 lead to cancer from the breast and female reproductive :, by 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 progression of tumors.

Symptoms of Breast Cancer

There are several forms in the growth of breast cancer:

- Nodular form, the commonest, is seen as a 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" of the breast and skin. For the initial two forms are characteristic signs and symptoms of inflammation: pain of the breast, a bright red color with the skin it raises temperature to 39 degrees C. In view of these symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that are named and are described these forms breast cancer. When tubular carcinoma cancer of the breast cover as being a "skin" of the contracting and decreasing in dimensions.

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

For small tumors of the breast, any symptoms arise. The most observant females and their husbands can detect tumor site in 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 strong knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, might be firmly fixed for the surrounding tissue or skin, usually painless, can reach a substantial size (greater than 3 to 5 cm and sometimes 10-15 cm).

Need to gauge the surface in the skin within the tumor: the malignant process is going to be observed retraction of the skin, picking up inside the folds, wrinkles, a signal of "lemon peel" - a neighborhood swelling of the skin in the tumor, can be a direct tumor invasion to your skin layer surface, then it is a bright red color and sprawl as "cauliflower."
