Breast Cancer

Among all cancers in females, he takes the initial place. In most cases, breast cancer 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, along with cancer from the nipple along with the nipple of the field (Paget's disease from the breast). For the nodular cancers are seen as an the node developing a diameter as high as several centimeters. In certain instances, a tight knot, is permeated with whitish layers tissue penetrating in to the surrounding dimply skin, in others - a soft, juicy on the cut, splits easily. Diffuse prostate cancer is covered to get a considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades your skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads along the surface with the breast and all the iron is roofed which has a dense shell.

In histological structure are the following varieties of breast cancers:

• 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 an varying examples of tissue and cell irregularities, which permitted to distinguish different amount of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which usually contains the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancer often are hormonal changes inside the body: the entry into menopause, should there be a dynamic restructuring of the hormonal regulation from the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, our bodies is going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most responsive to these changes, the breast tissue starts to dissolve and become replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role inside the progression of breast cancer. The excess hormones in the body generates a favorable background for developing the illness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (more than 12 months) to reduce the chance of developing breast cancer. On the other hand, abortion result in hormonal "explosion" in a very woman's body that could trigger the growth and development of tumors. So far there is no consensus about the impact for the development of tumors of hormonal contraceptive drugs, but it is thought that these drugs reduce the chance of developing breast cancer, but increase potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancer might cause harmful environmental factors: environmental surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a family of first-degree relatives with breast cancers (mothers and sisters) risk of developing a tumor increasing by greater than half - familial types of cancer.

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

The cause of breast cancer could be the results of radiation, for example irradiation in 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 reproductive :, by having an excess fatty tissue inside the body, it is another endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are many forms in the growth of breast cancers:

- Nodular form, the most frequent, is seen as a a dense knot of 0.5 to 5 cm or higher, it is seen as all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" from the breast and skin. For the first 2 forms are characteristic signs and symptoms of inflammation: pain from the breast, a bright red color with the skin it raises body's temperature to 39 degrees C. In view of those symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, which are named and are known these forms breast cancer. When tubular carcinoma breast cancers cover as being a "skin" of their contracting and decreasing in proportions.

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

For small tumors of the breast, any symptoms arise. The most observant women and their husbands can easily detect tumor site in the gland accidentally, 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 really is stationary or slightly shifted, could be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a tremendous size (more than 3 - 5 cm and quite often 10-15 cm).

Need to evaluate the surface of the skin over the tumor: the malignant process is going to be observed retraction from the skin, picking up inside the folds, wrinkles, a symptom of "lemon peel" - a local swelling with the skin on the tumor, is often a direct tumor invasion to skin surface, then it might be a bright red color and sprawl as "cauliflower."
