Breast Cancer

Among all cancers in females, he takes the first place. In most cases, cancer of the breast develops in 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 of the nipple and also the nipple with the field (Paget's disease of the breast). For the nodular cancers are seen as an the node having a diameter up to several centimeters. In certain cases, a tight knot, is permeated with whitish layers tissue penetrating in the surrounding dimply skin, in other people - a soft, juicy for the cut, splits easily. Diffuse cancer of prostate is roofed for any considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads across the surface from the breast and many types of the iron is included with a dense shell.

In histological structure would be the following varieties of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as a varying levels of tissue and cell irregularities, which able to distinguish different amount of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which in turn has got the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The reasons for breast cancer often are hormonal changes inside body: the entry into menopause, when there is an active restructuring in the hormonal regulation with the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, the body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most understanding of these changes, the breast type tissue actually starts to dissolve and become replaced by fat.

Scientifically established that the female hormones estrogen-, plays an integral role in the growth and development of breast cancer. The excess hormones in the body results in a favorable background for developing the disease. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (greater than one year) to cut back potential risk of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" in a woman's body that could trigger the growth and development of tumors. So far there is absolutely no consensus concerning the impact around the progression of tumors of hormonal contraceptive drugs, yet it's belief that these drugs reduce the chance of developing breast cancers, but increase the potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: the environment, as well as inflammatory diseases previously deferred breast - mastitis.

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

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

The source of breast cancers could be the results of radiation, for example 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 in the breast and female reproductive system, by having an excess dimply skin inside the body, it becomes a separate endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are many forms in the growth of breast cancers:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having 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 color in 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, which can be named and therefore are known as these forms cancer of the breast. When tubular carcinoma breast cancer cover like a "skin" of its contracting and decreasing in dimensions.

In certain cases, breast cancer manifests within the form of metastases in the lymph nodes on the affected side, often doesn't detect the tumor itself - show hidden breast cancer.

For small tumors in the breast, any symptoms arise. The most observant as well as their husbands have the ability to detect tumor site in the gland accidentally, 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 and only a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, could be firmly fixed for the surrounding tissue or skin, usually painless, can reach a substantial size (more than 3 - 5 cm and quite often 10-15 cm).

Need to assess the surface from the skin in the tumor: the malignant process will likely be observed retraction with the skin, picking up within the folds, wrinkles, a symptom of "lemon peel" - a neighborhood swelling in the skin over the tumor, is often a direct tumor invasion to skin surface, then it is a bright beautiful red colors and sprawl as "cauliflower."
