Breast Cancer

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

In histological structure include the following varieties of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as an varying levels of tissue and cell irregularities, which in a position to distinguish different degree of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which often has the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancers often are hormonal changes inside body: the entry into menopause, if you have a dynamic restructuring from the hormonal regulation from the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, the body will go through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most tuned in to these changes, the breast tissue begins to dissolve and turn into replaced by fat.

Scientifically established that this female hormones estrogen-, plays a key role inside continuing development of cancer of the breast. The excess hormones inside the body results in a favorable background for developing the condition. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (more than one year) to lessen the potential risk of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" inside a woman's body that could trigger the growth and development of tumors. So far there's no consensus concerning the impact about the growth and development of tumors of hormonal contraceptive drugs, but it is belief that these drugs reduce the risk of developing breast cancers, 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: environmental surroundings, along with inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a family of first-degree relatives with breast cancers (mothers and sisters) probability of having 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 don't lead to cancer, but simultaneously, create an unfavorable background for its development.

The reason behind breast cancer may be the results 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 lead to cancer with the breast and female reproductive system, by having an excess dimply skin inside body, it becomes another endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are many forms from the growth of breast cancer:

- Nodular form, the most frequent, is seen as a dense knot of 0.5 to cm or maybe more, it can be seen as all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" of the breast and skin. For the initial two forms are characteristic warning signs of inflammation: pain from the breast, a bright beautiful red colors with the skin it raises body's temperature to 39 degrees C. In view of these symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, which can be named and are known as these forms breast cancer. When tubular carcinoma cancer of the breast cover as being a "skin" of their contracting and decreasing in dimensions.

In certain cases, breast cancer manifests within the form of metastases within the lymph nodes around the affected side, often fails to detect the tumor itself - show hidden breast cancer.

For small tumors from the breast, any symptoms arise. The most observant as well as their husbands can detect tumor site within the gland by chance, 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 strong knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, might be firmly fixed on the surrounding tissue or skin, usually painless, can reach a tremendous size (greater than three to five cm and infrequently 10-15 cm).

Need to gauge the surface with the skin within the tumor: the malignant process will be observed retraction with the skin, obtaining inside the folds, wrinkles, a signal of "lemon peel" - a local swelling in the skin over the tumor, might be a direct tumor invasion to your skin layer surface, then it might be a bright red color and sprawl as "cauliflower."
