Breast Cancer

Among all cancers in women, he takes the initial place. In most cases, breast cancer 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, in addition to cancer of the nipple and the nipple with the field (Paget's disease in the breast). For the nodular cancers are seen as the node developing a diameter as high as several centimeters. In certain instances, a strong knot, is permeated with whitish layers tissue penetrating to the surrounding dimply skin, in others - a soft, juicy around the cut, splits easily. Diffuse prostate cancer is included for the 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 cases, the tumor spreads across the surface with the breast and many types of the iron is roofed which has a dense shell.

In histological structure will be 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 examples of tissue and cell irregularities, which allowed to distinguish different degree of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which usually has got the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancer often are hormonal changes inside the body: the entry into menopause, should there be an active restructuring in the hormonal regulation in 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 from the uterus) are most attentive to these changes, the breast type tissue actually starts to dissolve and be replaced by fat.

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

In addition, patients having a category of first-degree relatives with cancer of the breast (mothers and sisters) chance of developing a tumor increasing by a lot more than half - familial types of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not lead to cancer, but concurrently, create an unfavorable background for the development.

The cause of breast cancer will be the effects of radiation, like irradiation in 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 :, with the excess fat inside body, it might be another endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are many forms from the growth of cancer of the breast:

- Nodular form, the most typical, is characterized by a dense knot of 0.5 to five cm or higher, it really is seen as all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" with the breast and skin. For the initial two forms are characteristic signs of inflammation: pain of the breast, a bright red colorization in the skin it raises body temperature to 39 degrees C. In view of such symptoms often occur, and errors in carried out patients treated for inflammatory diseases, that happen to be named and so are known these forms cancer of the breast. When tubular carcinoma breast cancer cover as being a "skin" of their contracting and decreasing in dimensions.

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

For small tumors from the breast, any symptoms arise. The most observant ladies and their husbands can easily detect tumor site inside the 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 tight knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, might be firmly fixed on the surrounding tissue or skin, usually painless, can reach a tremendous size (over 3 to 5 cm and often 10-15 cm).

Need to assess the surface with the skin on the tumor: the malignant process will be observed retraction in the skin, picking up in the folds, wrinkles, a symptom of "lemon peel" - a nearby swelling of the skin on the tumor, might be a direct tumor invasion to your skin layer surface, then it becomes a bright red colorization and sprawl as "cauliflower."
