Breast Cancer

Among all cancers in ladies, he takes consumers. 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, in addition to cancer in the nipple along with the nipple with the field (Paget's disease with the breast). For the nodular cancers are characterized by the node creating a diameter up to several centimeters. In certain instances, a good knot, is permeated with whitish layers tissue penetrating to the surrounding fatty tissue, in others - a soft, juicy on the cut, splits easily. Diffuse cancer of the prostate is roofed for any considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades your skin layer and forms around the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads down the surface in the breast and all sorts of the iron is included which has a dense shell.

In histological structure are the following varieties of cancer of the breast:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as a varying levels of tissue and cell irregularities, which in a position to distinguish different degree of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which usually gets the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancers often are hormonal changes within the body: the entry into menopause, if you find an energetic restructuring in 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 in the uterus) are most tuned in to these changes, the breast growth actually starts to dissolve and become replaced by fat.

Scientifically established that the female hormones estrogen-, plays an important role within the development of cancer of the breast. The excess hormones inside body results in 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 (a lot more than one year) to relieve the potential risk of developing breast cancer. On the other hand, abortion cause hormonal "explosion" inside a woman's body that will trigger the progression of tumors. So far there isn't any consensus regarding the impact for the growth and development of tumors of hormonal contraceptive drugs, however it is belief that these drugs reduce potential risk of developing breast cancers, but increase the potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast could cause harmful environmental factors: environmental surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

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

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

The reason for breast cancer could be the results of radiation, for example 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 bring about cancer of the breast and female reproductive system, with the excess dimply skin in the body, it might be an outside 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 some forms in the growth of cancer of the breast:

- Nodular form, the commonest, is characterized by a dense knot of 0.5 to five cm or higher, it really is seen as a all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" from the breast and skin. For the first two forms are characteristic indications of inflammation: pain with the breast, a bright red color in the skin it raises temperature to 39 degrees C. In view of those symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, which can be named and are described these forms breast cancer. When tubular carcinoma breast cancers cover like a "skin" of their contracting and decreasing in space.

In some instances, cancer of the breast manifests within the form of metastases inside the lymph nodes for the affected side, often doesn't detect the tumor itself - show hidden breast cancers.

For small tumors with the breast, any symptoms arise. The most observant as well as their husbands can detect tumor site in the gland by accident, but in a 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 good knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, might be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a significant size (more than three to five cm and often 10-15 cm).

Need to evaluate the surface in the skin on the tumor: the malignant process will likely be observed retraction in the skin, picking up in the folds, wrinkles, an indication of "lemon peel" - a neighborhood swelling with the skin over the tumor, might be a direct tumor invasion to your skin layer surface, then it becomes a bright red colorization and sprawl as "cauliflower."
