Breast Cancer

Among all cancers in ladies, he takes the first 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, and also cancer in the nipple as well as the nipple from the field (Paget's disease in the breast). For the nodular cancers are characterized by the node developing a diameter of up to several centimeters. In certain instances, a good knot, is permeated with whitish layers tissue penetrating in to the surrounding dimply skin, in other people - a soft, juicy for the cut, splits easily. Diffuse cancer of the prostate is covered for the 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 instances, the tumor spreads across the surface from the breast and the iron is covered which has a dense shell.

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

• 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 a varying examples of tissue and cell irregularities, which permitted to distinguish different degree of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which usually has the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The reasons for breast cancer often are hormonal changes inside body: the entry into menopause, if you have a dynamic restructuring from the hormonal regulation of the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, one's body goes through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most tuned in to these changes, the breast type tissue actually starts to dissolve and be replaced by fat.

Scientifically established that this female hormones estrogen-, plays an integral role inside the continuing development of breast cancers. The excess hormones in the body creates a favorable background for developing the condition. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (a lot more than 12 months) to reduce the risk of developing breast cancer. On the other hand, abortion result in hormonal "explosion" in a woman's body that can trigger the continuing development of tumors. So far there is no consensus in regards to the impact for the growth and development of tumors of hormonal contraceptive drugs, but it's considered that these drugs reduce potential risk of developing breast cancer, but increase potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancer can cause harmful environmental factors: the planet, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a category of first-degree relatives with cancer of the breast (mothers and sisters) risk of making a tumor increasing by greater than half - familial kinds of cancer.

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not lead to cancer, but simultaneously, create an unfavorable background for its development.

The reason behind breast cancer may be the effects 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 bring about cancer in the breast and female the reproductive system, with the excess fat inside body, it will become a separate endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

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

- Nodular form, the most frequent, is seen as a a dense knot of 0.5 to 5 cm or higher, it really is seen as a all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" from the breast and skin. For the first two forms are characteristic signs of inflammation: pain from the breast, a bright red color with the skin it raises temperature to 39 degrees C. In view of the symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that happen to be named and are described these forms breast cancer. When tubular carcinoma cancer of the breast cover as a "skin" of the contracting and decreasing in proportions.

In some cases, cancer of the breast manifests inside form of metastases in the lymph nodes for the affected side, often fails to detect the tumor itself - show hidden cancer of the breast.

For small tumors from the breast, any symptoms arise. The most observant females and their husbands are able to detect tumor site within the gland by accident, but in a very 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 strong knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, may be firmly fixed for the surrounding tissue or skin, usually painless, can reach an important size (greater than 3 to 5 cm and often 10-15 cm).

Need to assess the surface with the skin within the tumor: the malignant process will likely be observed retraction from the skin, picking up within the folds, wrinkles, an indication of "lemon peel" - a local swelling in the skin within the tumor, may be a direct tumor invasion to the skin surface, then it is a bright beautiful red colors and sprawl as "cauliflower."
