Breast Cancer

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

In histological structure will be the following kinds of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers 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 amount of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which usually gets the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The reasons for breast cancers often are hormonal changes inside the body: the entry into menopause, should there be an energetic restructuring of 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 responsive to these changes, the breast growth starts to dissolve and stay replaced by fat.

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

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to result in cancer, but simultaneously, create an unfavorable background for its development.

The cause of cancer of the breast could be the results of radiation, including irradiation with 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 of the breast and female reproductive system, with the excess fatty tissue within the body, it is another endocrine organ and 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 cancer of the breast:

- Nodular form, the most typical, is seen as a dense knot of 0.5 to five cm or even more, it really is seen as an all in 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 signs and symptoms of inflammation: pain in the breast, a bright red colorization of the skin it raises body's 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 are known these forms cancer of the breast. When tubular carcinoma breast cancer cover as a "skin" of the contracting and decreasing in size.

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

For small tumors of the breast, any symptoms arise. The most observant as well as their husbands can easily detect tumor site within the gland by accident, but inside a large breast to detect small size hard knot. Revealed a knot could 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 can be stationary or slightly shifted, could be firmly fixed for the surrounding tissue or skin, usually painless, can reach an important size (more than three to five cm and quite often 10-15 cm).

Need to assess the surface with the skin over the tumor: the malignant process will likely be observed retraction in the skin, buying inside folds, wrinkles, an indicator of "lemon peel" - a local swelling with the skin over the tumor, may be a direct tumor invasion to your skin layer surface, then it becomes a bright beautiful red colors and sprawl as "cauliflower."
