Breast Cancer

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

In histological structure would be the following types 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 degrees of tissue and cell irregularities, which in a position to distinguish different amount of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which will contains the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The reasons for cancer of the breast often are hormonal changes within the body: the entry into menopause, if you find a dynamic restructuring from the hormonal regulation from the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, our bodies will go through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most understanding of these changes, the breast tissue starts to dissolve and become replaced by fat.

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

In addition, patients which has a category of first-degree relatives with breast cancers (mothers and sisters) likelihood of having a tumor increasing by more than half - familial varieties of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not lead to cancer, but as well, create an unfavorable background for the development.

The reason for breast cancers may be the outcomes of radiation, such as 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 cause cancer of the breast and female reproductive :, with an excess dimply skin inside the body, it might be an outside endocrine organ and begins 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 characterized by a dense knot of 0.5 to 5 cm or more, it is seen as an all with 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 first two forms are characteristic signs and symptoms of inflammation: pain from the breast, a bright beautiful red colors in the skin it raises body temperature to 39 degrees C. In view of the symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, which can be named and are known these forms breast cancers. When tubular carcinoma breast cancers cover as a "skin" of their contracting and decreasing in dimensions.

In some cases, cancer of the breast manifests inside the form of metastases inside lymph nodes on the affected side, often does not detect the tumor itself - show hidden cancer of the breast.

For small tumors with the breast, any symptoms arise. The most observant ladies and their husbands can easily detect tumor site in the gland by accident, but in a very 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 tight knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, may be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (greater than 3 - 5 cm and sometimes 10-15 cm).

Need to evaluate the surface of the skin within the tumor: the malignant process will probably be observed retraction in the skin, buying in the folds, wrinkles, an indication of "lemon peel" - a nearby swelling from the skin over the tumor, can be a direct tumor invasion to skin surface, then it becomes a bright red colorization and sprawl as "cauliflower."
