Breast Cancer

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

In histological structure include the following forms of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers can be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is seen as varying examples of tissue and cell irregularities, which able to distinguish different degree of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which often has the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes within the body: the entry into menopause, should there be a dynamic restructuring of the hormonal regulation with the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, your body will go through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most understanding of these changes, the breast type tissue actually starts to dissolve and turn into replaced by fat.

Scientifically established that this female hormones estrogen-, plays an integral role inside the continuing development of cancer of the breast. The excess hormones inside the body results in a favorable background for developing the condition. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (a lot more than 1 year) to lessen potential risk of developing cancer of the breast. On the other hand, abortion lead to hormonal "explosion" in a very woman's body that will trigger the development of tumors. So far there's no consensus about the impact for the growth and development of tumors of hormonal contraceptive drugs, however it is believed that these drugs reduce the risk of developing breast cancer, but increase the chance of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancers can cause harmful environmental factors: the surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't bring about cancer, but simultaneously, create an unfavorable background because of its development.

The reason behind breast cancer will be the effects of 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 cause cancer in the breast and female the reproductive system, having an excess dimply skin in the body, it becomes 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 some forms of the growth of cancer of the breast:

- Nodular form, the commonest, is seen as a dense knot of 0.5 to cm or even more, it really is seen as an all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having 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 beautiful red colors in the skin it raises body temperature to 39 degrees C. In view of the symptoms often occur, and errors in carried out patients treated for inflammatory diseases, which can be named and so are known these forms breast cancer. When tubular carcinoma cancer of the breast cover as a "skin" of its contracting and decreasing in size.

In certain instances, cancer of the breast manifests in the form of metastases in 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 can easily detect tumor site inside gland by chance, but inside a large breast to detect small size hard knot. Revealed a knot can be painful when pressed, round, smooth and agile, this speaks in favor of a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, may be firmly fixed on the surrounding tissue or skin, usually painless, can reach a tremendous size (a lot more than 3 - 5 cm and sometimes 10-15 cm).

Need to gauge the surface with the skin in the tumor: the malignant process is going to be observed retraction with the skin, collecting in the folds, wrinkles, a signal of "lemon peel" - an area swelling with the skin over the tumor, can be a direct tumor invasion to your skin surface, then it might be a bright red colorization and sprawl as "cauliflower."
