Breast Cancer

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

In histological structure include the following types of cancer of the breast:

• 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 a varying examples of tissue and cell irregularities, which permitted to distinguish different degree of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which in turn gets the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancer often are hormonal changes in the body: the entry into menopause, if you find an energetic restructuring of the hormonal regulation from the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, one's body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most attentive to these changes, the breast tissue begins to dissolve and be replaced by fat.

Scientifically established the female hormones estrogen-, plays an integral role in the growth and development of cancer of the breast. The excess hormones inside the body generates a favorable background for developing the disease. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (over 1 year) to relieve the chance of developing breast cancers. On the other hand, abortion bring about hormonal "explosion" in a woman's body that can trigger the progression of tumors. So far there is no consensus regarding the impact on the continuing 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 the potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancers can cause harmful environmental factors: the surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a family of first-degree relatives with breast cancer (mothers and sisters) likelihood of creating a tumor increasing by greater than half - familial forms of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not cause cancer, but as well, create an unfavorable background for its development.

The cause of cancer of the breast will be the results of radiation, for example 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 result in cancer from the breast and female reproductive system, with an excess dimply skin inside the body, it will become a different 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 from the growth of breast cancer:

- Nodular form, the most typical, is seen as an a dense knot of 0.5 to 5 cm or more, it's characterized by all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" with the breast and skin. For the first couple of forms are characteristic signs of inflammation: pain with the breast, a bright red colorization from the skin it raises body temperature to 39 degrees C. In view of such symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, which can be named and they are described these forms cancer of the breast. When tubular carcinoma breast cancers cover as being a "skin" of the company's contracting and decreasing in size.

In some instances, breast cancers manifests in the form of metastases within the lymph nodes for the affected side, often ceases to detect the tumor itself - show hidden cancer of the breast.

For small tumors of the breast, any symptoms arise. The most observant as well as their husbands can easily detect tumor site within the gland by accident, but in the large breast to detect small size hard knot. Revealed a knot could 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 on the surrounding tissue or skin, usually painless, can reach a significant size (a lot more than three to five cm and quite often 10-15 cm).

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