Breast Cancer

Among all cancers ladies, he takes consumers. In most cases, cancer of the breast 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 in the nipple and the nipple in the field (Paget's disease with the breast). For the nodular cancers are seen as the node creating a diameter as high as several centimeters. In some cases, a good knot, is permeated with whitish layers tissue penetrating in to the surrounding fat, on other occasions - a soft, juicy on the cut, splits easily. Diffuse cancer of prostate is roofed for a considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades your skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads across the surface in the breast and many types of the iron is roofed with a dense shell.

In histological structure are the following kinds of breast cancer:

• 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 a varying degrees of tissue and cell irregularities, which allowed to distinguish different amount of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which in turn has the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancers often are hormonal changes within the body: the entry into menopause, should there be an engaged restructuring in the hormonal regulation of the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, our bodies will go through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most tuned in to these changes, the breast tissue actually starts to dissolve and turn into replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role inside development of cancer of the breast. The excess hormones inside 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 how the birth and prolonged breastfeeding (more than twelve months) to lessen the risk of developing breast cancer. On the other hand, abortion cause hormonal "explosion" in the woman's body that will trigger the continuing development of tumors. So far there is no consensus concerning the impact for the development of tumors of hormonal contraceptive drugs, but it is thought that these drugs reduce the potential risk of developing cancer of the breast, but increase the potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancer might cause harmful environmental factors: environmental surroundings, in addition to inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not lead to cancer, but as well, create an unfavorable background due to the development.

The source of breast cancer will be the results of radiation, such as 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 cause cancer of the breast and female the reproductive system, with the excess dimply skin inside body, it might be a separate endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are some forms of the growth of breast cancers:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" of the breast and skin. For the initial two forms are characteristic signs of inflammation: pain in the breast, a bright beautiful red colors with the skin it raises body's temperature to 39 degrees C. In view of the symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, which can be named and are known these forms breast cancer. When tubular carcinoma cancer of the breast cover as a "skin" of the company's contracting and decreasing in dimensions.

In some instances, breast cancers manifests within the form of metastases inside lymph nodes around the affected side, often fails to 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 are able to detect tumor site inside gland unintentionally, 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 in support of a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, can be firmly fixed towards the surrounding tissue or skin, usually painless, can reach an important size (a lot more than 3 - 5 cm and sometimes 10-15 cm).

Need to assess the surface from the skin on the tumor: the malignant process will probably be observed retraction of the skin, obtaining inside the folds, wrinkles, an indicator of "lemon peel" - an area swelling in the skin on the tumor, may be a direct tumor invasion to skin surface, then it becomes a bright beautiful red colors and sprawl as "cauliflower."
