Breast Cancer

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

In histological structure will 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 characterized by 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 usually contains the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The factors behind cancer of the breast often are hormonal changes inside the body: the entry into menopause, should there be a dynamic restructuring from the hormonal regulation with the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, our bodies will go through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most attentive to these changes, the breast tissue begins to dissolve and become replaced by fat.

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

In addition, patients having a group of first-degree relatives with breast cancers (mothers and sisters) probability of having a tumor increasing by more than half - familial forms of cancer.

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not cause cancer, but concurrently, create an unfavorable background because of its development.

The source of cancer of the breast may be the results of radiation, for example irradiation of 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 with the breast and female reproductive :, having an excess fat in the body, it is a separate endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are several forms of the growth of cancer of the breast:

- Nodular form, the most common, is seen as a dense knot of 0.5 to five cm or maybe more, it really is seen as all from the following symptoms;

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

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

For small tumors with the breast, any symptoms arise. The most observant women and their husbands are able to detect tumor site within the gland by accident, but inside a large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks for a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, can be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (over 3 - 5 cm and quite often 10-15 cm).

Need to gauge the surface with the skin on the tumor: the malignant process will probably be observed retraction from the skin, obtaining in the folds, wrinkles, a symptom of "lemon peel" - a neighborhood swelling from the skin on the tumor, is often a direct tumor invasion to your skin surface, then it is a bright red colorization and sprawl as "cauliflower."
