Breast Cancer

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

In histological structure would be the following types of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying examples of tissue and cell irregularities, which able to distinguish different level of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which usually contains the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes inside body: the entry into menopause, if you find an energetic restructuring with the hormonal regulation with the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, the body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most tuned in to these changes, the breast growth begins to dissolve and stay replaced by fat.

Scientifically established that this female hormones estrogen-, plays a vital role inside the growth and development of breast cancer. The excess hormones within 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 the birth and prolonged breastfeeding (a lot more than 12 months) to relieve 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 progression of tumors. So far there is absolutely no consensus concerning the impact about the progression of tumors of hormonal contraceptive drugs, but it's believed that these drugs reduce the risk of developing breast cancers, 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: environmental surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a family of first-degree relatives with breast cancers (mothers and sisters) probability of making a tumor increasing by more than half - familial varieties of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't cause cancer, but concurrently, create an unfavorable background for its development.

The reason for breast cancer may be the connection between radiation, for example 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 :, having an excess fat inside body, it is 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 several forms with the growth of breast cancer:

- Nodular form, the most typical, is seen as an a dense knot of 0.5 to 5 cm or even more, it can be seen as an all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" of the breast and skin. For the initial two forms are characteristic indications of inflammation: pain of the breast, a bright red colorization of the skin it raises temperature to 39 degrees C. In view of the 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 being a "skin" of the contracting and decreasing in size.

In some cases, breast cancer manifests inside form of metastases inside lymph nodes for the affected side, often doesn't detect the tumor itself - show hidden breast cancer.

For small tumors of the breast, any symptoms arise. The most observant females and their husbands can easily detect tumor site inside the gland by accident, but in the 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 strong knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, may be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a tremendous size (more than three to five cm and quite often 10-15 cm).

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