Breast Cancer

Among all cancers in females, he takes the initial 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, in addition to cancer of the nipple as well as the nipple in the field (Paget's disease from the breast). For the nodular cancers are seen as an the node using a diameter up to several centimeters. In certain instances, a good knot, is permeated with whitish layers tissue penetrating into the surrounding dimply skin, in others - a soft, juicy about the cut, splits easily. Diffuse cancer of prostate is roofed for a considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades skin 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 included with a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as varying degrees 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 will contains the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The reasons for breast cancers often are hormonal changes within the body: the entry into menopause, if you have an energetic restructuring in the hormonal regulation of the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, your body is going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most tuned in to these changes, the breast growth starts to dissolve and stay replaced by fat.

Scientifically established that this female hormones estrogen-, plays an integral role within the progression of breast cancers. The excess hormones inside body generates a favorable background for developing the illness. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (a lot more than 12 months) to relieve the potential risk of developing breast cancer. On the other hand, abortion lead to hormonal "explosion" in a very woman's body that could trigger the continuing development of tumors. So far there is no consensus in regards to the impact about the development of tumors of hormonal contraceptive drugs, but it is belief that these drugs reduce potential risk of developing breast cancer, but increase potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: the surroundings, and also inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not result in cancer, but at the same time, create an unfavorable background due to the development.

The source of breast cancer would be the outcomes of radiation, like 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 lead to cancer of the breast and female reproductive :, with an excess fatty tissue inside the body, it will become a separate endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are many forms with the growth of breast cancers:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" from the breast and skin. For the first two forms are characteristic signs of inflammation: pain with the breast, a bright red colorization from the skin it raises temperature to 39 degrees C. In view of these symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, that are named and so are referred to these forms breast cancer. When tubular carcinoma breast cancer cover as being a "skin" of their contracting and decreasing in dimensions.

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

For small tumors from the breast, any symptoms arise. The most observant women and their husbands have the ability to detect tumor site in the gland by accident, 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 favor 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, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach a tremendous size (greater than 3 - 5 cm and often 10-15 cm).

Need to assess the surface of the skin on the tumor: the malignant process will likely be observed retraction in the skin, collecting inside the folds, wrinkles, a signal of "lemon peel" - a nearby swelling with the skin on the tumor, may be a direct tumor invasion to the skin surface, then it might be a bright red color and sprawl as "cauliflower."
