Breast Cancer

Among all cancers in females, he takes the first place. In most cases, breast cancers 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, as well as cancer from the nipple and the nipple with the field (Paget's disease with the breast). For the nodular cancers are seen as an the node having a diameter all the way to several centimeters. In some cases, a good knot, is permeated with whitish layers tissue penetrating in the surrounding dimply skin, in other people - a soft, juicy around the cut, splits easily. Diffuse prostate type of cancer is included for the considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades the skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads across the surface of the breast and all sorts of the iron is covered having a dense shell.

In histological structure are the following varieties of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as an varying levels of tissue and cell irregularities, which permitted to distinguish different a higher level malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which will contains the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The causes of cancer of the breast often are hormonal changes inside body: the entry into menopause, should there be an energetic restructuring with the hormonal regulation in the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, the body is going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most responsive to these changes, the breast tissue starts to dissolve and turn into replaced by fat.

Scientifically established the female hormones estrogen-, plays a key role within the continuing development of breast cancers. The excess hormones in the body results in a favorable background for developing the disease. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (a lot more than 1 year) to relieve the risk of developing breast cancer. On the other hand, abortion cause hormonal "explosion" in the woman's body that can trigger the continuing development of tumors. So far there isn't any consensus about the impact around the development of tumors of hormonal contraceptive drugs, however it is believed that these drugs reduce the risk of developing breast cancers, but increase the chance of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancer may cause harmful environmental factors: the surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to cause cancer, but simultaneously, create an unfavorable background for its development.

The cause of breast cancer may be the effects 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 result in cancer in the breast and female reproductive :, with the excess dimply skin in the body, it might be an outside endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are many forms from the growth of breast cancer:

- Nodular form, the most frequent, is seen as a dense knot of 0.5 to cm or more, it is seen as all in 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 signs and symptoms of inflammation: pain from 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 carried out patients treated for inflammatory diseases, which are named and therefore are described these forms breast cancer. When tubular carcinoma breast cancer cover as a "skin" of the company's contracting and decreasing in dimensions.

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

For small tumors from the breast, any symptoms arise. The most observant ladies and their husbands can easily detect tumor site inside gland by accident, but in a very large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks and only 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 significant size (over three to five cm and quite often 10-15 cm).

Need to assess the surface from the skin over the tumor: the malignant process is going to be observed retraction from the skin, picking up inside folds, wrinkles, a signal of "lemon peel" - a local swelling from the skin over the tumor, can be a direct tumor invasion to skin surface, then it might be a bright beautiful red colors and sprawl as "cauliflower."
