Breast Cancer

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

In histological structure are the following forms 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 levels of tissue and cell irregularities, which able to distinguish different level of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which will contains the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The factors behind cancer of the breast often are hormonal changes inside the body: the entry into menopause, if you have a dynamic restructuring in the hormonal regulation with the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, one's body goes through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most understanding of these changes, the breast growth starts to dissolve and be replaced by fat.

Scientifically established how the female hormones estrogen-, plays an important role in the growth and development of cancer of the breast. The excess hormones inside 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 how the birth and prolonged breastfeeding (a lot more than twelve months) to reduce the risk of developing breast cancer. On the other hand, abortion result in hormonal "explosion" in a very woman's body that will trigger the development of tumors. So far there is no consensus concerning the impact on the growth and development of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce the potential risk of developing breast cancers, but increase the risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancer may cause harmful environmental factors: the environment, and also inflammatory diseases previously deferred breast - mastitis.

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

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

The cause of cancer of the breast will be the connection between radiation, for example 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 lead to cancer from the breast and female reproductive system, having an excess dimply skin 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 some forms of the growth of cancer of the breast:

- Nodular form, the most common, is seen as a dense knot of 0.5 to 5 cm or maybe more, it really is seen as a all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" in the breast and skin. For the initial two forms are characteristic warning signs of inflammation: pain in the breast, a bright red colorization from the skin it raises body temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, which are named and are described these forms breast cancer. When tubular carcinoma breast cancer cover as a "skin" of its contracting and decreasing in space.

In some instances, breast cancer manifests inside the form of metastases inside lymph nodes on the affected side, often does not detect the tumor itself - show hidden breast cancer.

For small tumors of the breast, any symptoms arise. The most observant ladies and their husbands have the ability to detect tumor site inside gland unintentionally, but in the large breast to detect small size hard knot. Revealed a knot may be painful when pressed, round, smooth and agile, this speaks for a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach an important size (more than three to five cm and infrequently 10-15 cm).

Need to evaluate the surface with the skin in the tumor: the malignant process will be observed retraction with the skin, collecting inside folds, wrinkles, a symptom of "lemon peel" - an area swelling from the skin within the tumor, can be a direct tumor invasion to the skin surface, then it becomes a bright beautiful red colors and sprawl as "cauliflower."
