Breast Cancer

Among all cancers in females, he takes the first place. 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, and also cancer with the nipple as well as the nipple of the field (Paget's disease of the breast). For the nodular cancers are characterized by the node developing a diameter of up to several centimeters. In some instances, a decent knot, is permeated with whitish layers tissue penetrating into the surrounding fatty tissue, on other occasions - a soft, juicy for the cut, splits easily. Diffuse cancer of prostate is roofed for the considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades the skin and forms for the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads across the surface in the breast and all the iron is covered which has a dense shell.

In histological structure would be the following types 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 characterized by varying degrees of tissue and cell irregularities, which in a position to distinguish different amount of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which in turn gets the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The causes of breast cancers often are hormonal changes within the body: the entry into menopause, if you have an engaged restructuring of the hormonal regulation of 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 with the uterus) are most responsive to these changes, the breast growth begins to dissolve and turn into replaced by fat.

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

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

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

The reason behind breast cancers will be the effects of radiation, including 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 :, with the excess dimply skin in the body, it will become 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 many forms with the growth of cancer of the breast:

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

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

In certain cases, cancer of the breast manifests inside the form of metastases inside lymph nodes about the affected side, often doesn't detect the tumor itself - show hidden breast cancers.

For small tumors in the breast, any symptoms arise. The most observant as well as their husbands can detect tumor site within the gland by chance, but inside 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 good knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, can be firmly fixed on the surrounding tissue or skin, usually painless, can reach a tremendous size (over 3 - 5 cm and quite often 10-15 cm).

Need to evaluate the surface of the skin in the tumor: the malignant process is going to be observed retraction from the skin, buying within the folds, wrinkles, a signal of "lemon peel" - a local swelling with the skin within the tumor, is often a direct tumor invasion to skin surface, then it might be a bright red color and sprawl as "cauliflower."
