Breast Cancer

Among all cancers in women, he takes the ultimate place. In most cases, breast cancer 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 in the field (Paget's disease with the breast). For the nodular cancers are seen as the node developing a diameter as high as several centimeters. In some cases, a good knot, is permeated with whitish layers tissue penetrating to the surrounding fatty tissue, on other occasions - a soft, juicy for the cut, splits easily. Diffuse cancer of prostate is covered for any considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades your skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads down the surface from the breast and all the iron is covered which has a dense shell.

In histological structure include the following forms of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancer could be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

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

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes in the body: the entry into menopause, when there is an active restructuring of the hormonal regulation of the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, the body is going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most understanding of these changes, the breast growth starts to dissolve and stay replaced by fat.

Scientifically established how the female hormones estrogen-, plays a vital role within the continuing development of cancer of the breast. The excess hormones in the body results in a favorable background for developing the sickness. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (a lot more than twelve months) to relieve the potential risk of developing breast cancers. On the other hand, abortion cause hormonal "explosion" inside a woman's body that can trigger the continuing development of tumors. So far there is no consensus about the impact for the growth and development of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce potential risk of developing breast cancers, but increase potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancers may cause harmful environmental factors: the surroundings, in addition to inflammatory diseases previously deferred breast - mastitis.

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

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

The source of cancer of the breast would be the outcomes of radiation, such as 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 cause cancer from the breast and female reproductive system, having an excess fat in the body, it might be an outside endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are some forms with the growth of breast cancer:

- Nodular form, the most common, is seen as a a dense knot of 0.5 to five cm or higher, it's characterized by all in 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 couple of forms are characteristic signs and symptoms of inflammation: pain in the breast, a bright red colorization with the skin it raises temperature to 39 degrees C. In view of these symptoms often occur, and errors in carried out patients treated for inflammatory diseases, that are named and therefore are known as these forms breast cancers. When tubular carcinoma breast cancer cover as a "skin" of the company's contracting and decreasing in proportions.

In certain instances, breast cancers manifests inside form of metastases within the lymph nodes around 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 detect tumor site inside 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 and only a benign tumor. Signs of malignancy other: a tight 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 tremendous size (over three to five cm and quite often 10-15 cm).

Need to assess the surface with the skin on the tumor: the malignant process will probably be observed retraction with the skin, buying in the folds, wrinkles, a signal of "lemon peel" - a nearby swelling with the skin on the tumor, may be a direct tumor invasion to your skin surface, then it is a bright red colorization and sprawl as "cauliflower."
