Breast Cancer

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

In histological structure would be the following types of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive cancer of the breast may 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 allowed to distinguish different a higher level malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which in turn contains the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

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

Scientifically established the female hormones estrogen-, plays an important role within the progression of breast cancer. The excess hormones inside the body generates a favorable background for developing the condition. 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 lessen the potential risk of developing breast cancer. On the other hand, abortion cause hormonal "explosion" in a very woman's body that can trigger the continuing development of tumors. So far there is no consensus concerning the impact around the growth and development of tumors of hormonal contraceptive drugs, but it is belief that these drugs reduce the risk of developing cancer of the breast, but increase the chance of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast may cause harmful environmental factors: the environment, and also inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not result in cancer, but as well, create an unfavorable background for the development.

The reason for cancer of the breast will be the outcomes of radiation, like 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 result in cancer in the breast and female the reproductive system, by having an excess fat in the body, it will become an outside endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are some forms of the growth of cancer of the breast:

- Nodular form, the commonest, is seen as an a dense knot of 0.5 to cm or more, it can be seen as a all with 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 first 2 forms are characteristic warning signs of inflammation: pain from the breast, a bright red color from the skin it raises temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that are named and are known these forms breast cancer. When tubular carcinoma breast cancer cover being a "skin" of the contracting and decreasing in size.

In certain cases, breast cancer manifests inside 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 as well as their husbands can detect tumor site in the gland accidentally, 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 for a benign tumor. Signs of malignancy other: a strong knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, may be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a tremendous size (a lot more than 3 to 5 cm and infrequently 10-15 cm).

Need to assess the surface from the skin on the tumor: the malignant process will be observed retraction with the skin, obtaining in the folds, wrinkles, an indication of "lemon peel" - a neighborhood swelling with the skin on the tumor, is often a direct tumor invasion to the skin surface, then it will become a bright red color and sprawl as "cauliflower."
