Breast Cancer

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

In histological structure are the following varieties of breast cancers:

• 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 examples of tissue and cell irregularities, which able to distinguish different level of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which often has got the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes inside body: the entry into menopause, if you find an engaged restructuring of the hormonal regulation of the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, the body is going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most attentive to these changes, the breast growth begins to dissolve and turn into replaced by fat.

Scientifically established the female hormones estrogen-, plays an integral role inside progression of breast cancers. The excess hormones in the body creates a favorable background for developing the sickness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (a lot more than twelve months) to relieve potential risk of developing breast cancer. On the other hand, abortion lead to hormonal "explosion" in a woman's body that will trigger the continuing development of tumors. So far there is no consensus concerning the impact around the continuing development of tumors of hormonal contraceptive drugs, but it's thought that these drugs reduce the risk of developing breast cancers, but increase the risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: environmental surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases for example 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 for cancer of the breast will be the effects of radiation, including irradiation in 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 lead to cancer from the breast and female reproductive system, with an excess fatty tissue inside the body, it will become an outside endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are a couple of forms from 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 more, it's characterized by all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" in the breast and skin. For the initial two forms are characteristic indications of inflammation: pain in the breast, a bright red colorization in the skin it raises body's temperature to 39 degrees C. In view of those symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, that happen to be named and are known these forms cancer of the breast. When tubular carcinoma cancer of the breast cover as a "skin" of their contracting and decreasing in dimensions.

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

For small tumors in the breast, any symptoms arise. The most observant women and their husbands can easily detect tumor site within the gland accidentally, but in a large breast to detect small size hard knot. Revealed a knot could 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's stationary or slightly shifted, can be firmly fixed for the surrounding tissue or skin, usually painless, can reach a substantial size (more than 3 to 5 cm and quite often 10-15 cm).

Need to gauge the surface with the skin within the tumor: the malignant process is going to be observed retraction of the skin, buying inside folds, wrinkles, a signal of "lemon peel" - an area swelling with the skin in the tumor, can be a direct tumor invasion to your skin surface, then it will become a bright beautiful red colors and sprawl as "cauliflower."
