Breast Cancer

Among all cancers in women, he takes the ultimate place. In most cases, breast cancers 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 from the nipple and the nipple with the field (Paget's disease of the breast). For the nodular cancers are seen as an the node developing a diameter up to several centimeters. In some instances, a good knot, is permeated with whitish layers tissue penetrating to the surrounding fat, in other people - a soft, juicy for the cut, splits easily. Diffuse cancer of prostate is covered for any considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades your skin layer and forms on the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads down the surface of the breast and the iron is roofed using a dense shell.

In histological structure would be the following forms of cancer of the breast:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as varying examples of tissue and cell irregularities, which permitted to distinguish different degree of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which will contains the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The reasons for breast cancers often are hormonal changes in the body: the entry into menopause, if you have an energetic restructuring of the hormonal regulation in the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, our bodies goes through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most tuned in to these changes, the breast growth begins to dissolve and be replaced by fat.

Scientifically established that the female hormones estrogen-, plays an integral role in the continuing development of breast cancers. The excess hormones inside body creates a favorable background for developing the illness. 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 potential risk of developing breast cancer. On the other hand, abortion lead to hormonal "explosion" in the woman's body that could trigger the progression of tumors. So far there isn't any consensus in regards to the impact on the development of tumors of hormonal contraceptive drugs, yet it's belief that these drugs reduce potential risk of developing breast cancers, but increase potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: environmental surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a group of first-degree relatives with breast cancer (mothers and sisters) chance of creating a tumor increasing by over half - familial forms of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not result in cancer, but simultaneously, create an unfavorable background because of its development.

The reason behind cancer of the breast may be the connection between radiation, including 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 result in cancer of the breast and female reproductive :, with the excess fatty tissue inside the body, it might be a different 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 of the growth of breast cancer:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" of the breast and skin. For the first two forms are characteristic signs and symptoms of inflammation: pain from 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 proper diagnosis of patients treated for inflammatory diseases, that are named and therefore are described these forms breast cancer. When tubular carcinoma cancer of the breast cover as being a "skin" of the contracting and decreasing in proportions.

In some instances, breast cancers manifests within the form of metastases inside lymph nodes for the affected side, often fails to detect the tumor itself - show hidden breast cancer.

For small tumors of the breast, any symptoms arise. The most observant as well as their husbands have the ability to detect tumor site inside the gland by chance, 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 in support of a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, may be firmly fixed to the surrounding tissue or skin, usually painless, can reach an important size (over 3 to 5 cm and often 10-15 cm).

Need to assess the surface in the skin on the tumor: the malignant process is going to be observed retraction from the skin, buying inside the folds, wrinkles, a signal of "lemon peel" - a neighborhood swelling from the skin on the tumor, might be a direct tumor invasion to the skin surface, then it is a bright beautiful red colors and sprawl as "cauliflower."
