Breast Cancer

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

In histological structure include the following forms of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers can 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 allowed to distinguish different degree of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which will has got the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancer often are hormonal changes inside the body: the entry into menopause, if you have a dynamic restructuring from the hormonal regulation in the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, our bodies is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most responsive to these changes, the breast growth actually starts to dissolve and stay replaced by fat.

Scientifically established how the female hormones estrogen-, plays a vital role in the development of breast cancer. The excess hormones in the body results in a favorable background for developing the sickness. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (more than twelve months) to lessen potential risk of developing cancer of the breast. On the other hand, abortion result in hormonal "explosion" inside a woman's body that may trigger the development of tumors. So far there's no consensus in regards to the impact around the continuing development of tumors of hormonal contraceptive drugs, however it is belief that these drugs reduce the potential risk of developing breast cancers, but increase potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancer might cause harmful environmental factors: the surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

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

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

The reason behind breast cancer may be the outcomes of radiation, including irradiation of 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 from the breast and female reproductive :, having an excess fat within the body, it will become an outside endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are some forms in the growth of breast cancer:

- Nodular form, the commonest, is seen as an a dense knot of 0.5 to cm or even more, it can be seen as a all of 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 first couple of forms are characteristic indications of inflammation: pain of the breast, a bright red colorization from the skin it raises body temperature to 39 degrees C. In view of those symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that are named and therefore are known as these forms cancer of the breast. When tubular carcinoma cancer of the breast cover being a "skin" of the contracting and decreasing in space.

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

For small tumors from the breast, any symptoms arise. The most observant as well as their husbands can detect tumor site in the gland unintentionally, but in a very 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 tight knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, can be firmly fixed on the surrounding tissue or skin, usually painless, can reach a substantial size (over three to five cm and quite often 10-15 cm).

Need to gauge the surface of the skin on the tumor: the malignant process will likely be observed retraction in the skin, buying within the folds, wrinkles, an indication of "lemon peel" - a local swelling of the skin over the tumor, is often a direct tumor invasion to skin surface, then it becomes a bright red color and sprawl as "cauliflower."
