Breast Cancer

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

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

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

Causes of Breast Cancer.

The reasons behind cancer of the breast often are hormonal changes in the body: the entry into menopause, should there be an active restructuring of the hormonal regulation from the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, one's body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most attentive to these changes, the breast growth begins to dissolve and become replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role inside the progression of cancer of the breast. The excess hormones inside the body produces a favorable background for developing the sickness. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (over 1 year) to cut back the potential risk of developing breast cancer. On the other hand, abortion lead to hormonal "explosion" inside a woman's body that may trigger the continuing development of tumors. So far there is no consensus about the impact around the growth and development of tumors of hormonal contraceptive drugs, yet it's thought that these drugs reduce the potential risk of developing breast cancer, but increase the potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a category of first-degree relatives with breast cancer (mothers and sisters) likelihood of having a tumor increasing by greater than half - familial kinds of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not result in cancer, but at the same time, create an unfavorable background because of its development.

The cause of breast cancer could be the effects of radiation, for example irradiation from 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 the reproductive system, by having an excess fat in the body, it will become 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 some forms in the growth of cancer of the breast:

- Nodular form, the most common, is seen as an a dense knot of 0.5 to five cm or higher, it can be seen as all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" in the breast and skin. For the first couple of forms are characteristic signs of inflammation: pain with the breast, a bright beautiful red colors from 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, that are named and therefore are known as these forms cancer of the breast. When tubular carcinoma breast cancers cover as being a "skin" of the company's contracting and decreasing in proportions.

In certain instances, breast cancers manifests in the form of metastases within the lymph nodes for the affected side, often ceases to detect the tumor itself - show hidden breast cancers.

For small tumors of the breast, any symptoms arise. The most observant as well as their husbands are able to detect tumor site within the gland accidentally, but inside a large breast to detect small size hard knot. Revealed a knot may 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 really is stationary or slightly shifted, may be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a substantial size (greater than 3 to 5 cm and infrequently 10-15 cm).

Need to gauge the surface in the skin on the tumor: the malignant process will be observed retraction of the skin, buying in the folds, wrinkles, a signal of "lemon peel" - a nearby swelling in the skin in the tumor, may be a direct tumor invasion to your skin surface, then it is a bright beautiful red colors and sprawl as "cauliflower."
