Breast Cancer

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

In histological structure will be the following forms 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 seen as varying levels of tissue and cell irregularities, which allowed to distinguish different level of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which will gets the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes in the body: the entry into menopause, should there be an energetic restructuring from the hormonal regulation with the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, the body is going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most responsive to these changes, the breast type tissue actually starts to dissolve and stay replaced by fat.

Scientifically established how the female hormones estrogen-, plays an important role in the progression of cancer of the breast. The excess hormones within the body creates a favorable background for developing the illness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (over 1 year) to reduce potential risk of developing breast cancers. On the other hand, abortion bring about hormonal "explosion" inside a woman's body that may trigger the continuing development of tumors. So far there is no consensus regarding the impact for the development of tumors of hormonal contraceptive drugs, but it's considered that these drugs reduce potential risk of developing cancer of the breast, but increase the chance of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancer may cause harmful environmental factors: the surroundings, and also inflammatory diseases previously deferred breast - mastitis.

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

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

The reason behind breast cancers could 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 result in cancer in the breast and female reproductive :, with the excess fat inside body, it might be a different endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are some forms of 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 more, it can be seen as an all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" of the breast and skin. For the initial two forms are characteristic indications of inflammation: pain from the breast, a bright beautiful red colors in 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 so are known these forms cancer of the breast. When tubular carcinoma breast cancers cover as a "skin" of its contracting and decreasing in size.

In certain instances, breast cancer manifests inside form of metastases in the lymph nodes around the affected side, often does not detect the tumor itself - show hidden cancer of the breast.

For small tumors of the breast, any symptoms arise. The most observant females and their husbands are able to detect tumor site in the gland accidentally, but inside a large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks in favor of a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, might be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a significant size (greater than 3 - 5 cm and sometimes 10-15 cm).

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