Breast Cancer

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

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

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancer might be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is seen as varying examples 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 in turn contains the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

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

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

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

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't lead to cancer, but simultaneously, create an unfavorable background because of its development.

The reason for breast cancer will be the outcomes of radiation, including irradiation with 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 of the breast and female reproductive :, with the 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 some forms in the growth of breast cancer:

- Nodular form, the commonest, is seen as a dense knot of 0.5 to cm or more, it really is seen as all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" of the breast and skin. For the first 2 forms are characteristic signs and symptoms of inflammation: pain from the breast, a bright red colorization in 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 are named and they are known these forms breast cancers. When tubular carcinoma cancer of the breast cover as being a "skin" of their contracting and decreasing in size.

In certain instances, breast cancer manifests in the form of metastases inside the lymph nodes about the affected side, often does not detect the tumor itself - show hidden breast cancers.

For small tumors of the breast, any symptoms arise. The most observant females and their husbands can easily detect tumor site in 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 and only a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, may be firmly fixed for the surrounding tissue or skin, usually painless, can reach an important size (a lot more than 3 - 5 cm and infrequently 10-15 cm).

Need to gauge the surface from the skin over the tumor: the malignant process will be observed retraction of the skin, picking up within the folds, wrinkles, an indicator of "lemon peel" - a nearby swelling from the skin on the tumor, may be a direct tumor invasion to your skin layer surface, then it becomes a bright red colorization and sprawl as "cauliflower."
