Breast Cancer

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

In histological structure will be the following forms of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

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

Causes of Breast Cancer.

The reasons for breast cancer often are hormonal changes within the body: the entry into menopause, if you have an energetic restructuring from the hormonal regulation of the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, our bodies is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most attentive to these changes, the breast type tissue begins to dissolve and become replaced by fat.

Scientifically established how the female hormones estrogen-, plays a key role within the development of breast cancer. The excess hormones inside the body produces a favorable background for developing the sickness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (greater than twelve months) to lessen the chance of developing breast cancer. On the other hand, abortion bring about hormonal "explosion" in a very woman's body that may trigger the growth and development of tumors. So far there is no consensus concerning the impact for the progression of tumors of hormonal contraceptive drugs, however it is thought that these drugs reduce potential risk of developing breast cancers, but increase the chance of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast can cause harmful environmental factors: environmental surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

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

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

The source of cancer of the breast will be the results of radiation, including 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 bring about cancer with the breast and female the reproductive system, with the excess dimply skin inside the body, it is another endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are many forms in the growth of breast cancer:

- Nodular form, the most frequent, is seen as a dense knot of 0.5 to cm or higher, it is characterized by 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 initial two forms are characteristic signs of inflammation: pain with the breast, a bright red color with the skin it raises body temperature to 39 degrees C. In view of the symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that happen to be named and they are referred to these forms cancer of the breast. When tubular carcinoma cancer of the breast cover as a "skin" of its contracting and decreasing in space.

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

For small tumors from the breast, any symptoms arise. The most observant as well as their husbands have the ability to detect tumor site within the gland unintentionally, but in a large breast to detect small size hard knot. Revealed a knot might 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 really is stationary or slightly shifted, could be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a substantial size (a lot more than three to five cm and sometimes 10-15 cm).

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