Breast Cancer

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

In histological structure are the following varieties of cancer of the breast:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancer 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 able to distinguish different a higher level malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which often has the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The reasons for breast cancers often are hormonal changes inside the body: the entry into menopause, if you find an engaged restructuring from the hormonal regulation of the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, your body is going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most understanding of these changes, the breast tissue actually starts to dissolve and stay replaced by fat.

Scientifically established that the female hormones estrogen-, plays an important role inside the development of breast cancer. The excess hormones inside body creates a favorable background for developing the illness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (over 12 months) to relieve potential risk of developing cancer of the breast. On the other hand, abortion result in hormonal "explosion" inside a woman's body that may trigger the growth and development of tumors. So far there is absolutely no consensus about the impact for the continuing development of tumors of hormonal contraceptive drugs, but it is belief that these drugs reduce the risk of developing breast cancers, but increase the potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast could cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to cause cancer, but at the same time, create an unfavorable background for the development.

The reason behind breast cancer could be the outcomes of radiation, such as 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 cause cancer from the breast and female reproductive system, with the excess fatty tissue within the body, it is a separate 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 of the growth of breast cancer:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" with the breast and skin. For the initial two forms are characteristic warning signs of inflammation: pain with the breast, a bright red color of the skin it raises body temperature to 39 degrees C. In view of those symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, which can be named and so are known these forms breast cancer. When tubular carcinoma breast cancer cover as being a "skin" of its contracting and decreasing in size.

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

For small tumors from the breast, any symptoms arise. The most observant as well as their husbands have the ability to detect tumor site in the gland unintentionally, but in the large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks in support 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, could be firmly fixed on the surrounding tissue or skin, usually painless, can reach a significant size (more than 3 - 5 cm and sometimes 10-15 cm).

Need to gauge the surface of the skin on the tumor: the malignant process is going to be observed retraction in the skin, obtaining inside the folds, wrinkles, a signal of "lemon peel" - a local swelling in the skin over the tumor, might be a direct tumor invasion to skin surface, then it might be a bright red colorization and sprawl as "cauliflower."
