Breast Cancer

Among all cancers ladies, he takes the initial place. In most cases, breast cancer 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 of the nipple and the nipple from the field (Paget's disease of the breast). For the nodular cancers are seen as an the node having a diameter up to several centimeters. In certain cases, a strong knot, is permeated with whitish layers tissue penetrating to the surrounding fat, on other occasions - a soft, juicy for the cut, splits easily. Diffuse prostate type of cancer is roofed to get a considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades your skin and forms for the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads down the surface with the breast and the iron is roofed having a dense shell.

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

• 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 varying degrees of tissue and cell irregularities, which allowed to distinguish different degree of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which in turn contains the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancer often are hormonal changes within the body: the entry into menopause, if you find an active restructuring from the hormonal regulation from the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, our bodies is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most tuned in to these changes, the breast type tissue begins to dissolve and stay replaced by fat.

Scientifically established the female hormones estrogen-, plays a vital role in the progression of breast cancer. The excess hormones within the body produces a favorable background for developing the illness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (greater than 1 year) to reduce the potential risk of developing breast cancer. On the other hand, abortion result in hormonal "explosion" in a woman's body that will trigger the continuing development of tumors. So far there's no consensus regarding the impact on the progression of tumors of hormonal contraceptive drugs, but it's considered that these drugs reduce the risk of developing breast cancers, but increase potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: the environment, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a family of first-degree relatives with cancer of the breast (mothers and sisters) likelihood of having a tumor increasing by a lot more than half - familial varieties of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to result in cancer, but at the same time, create an unfavorable background due to the development.

The cause of breast cancer could be the results of radiation, for example irradiation of 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 with the breast and female reproductive system, having an excess fat within the body, it is a separate 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 several forms with the growth of cancer of the breast:

- Nodular form, the most common, is seen as an a dense knot of 0.5 to 5 cm or even more, it really is characterized by all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" in the breast and skin. For the first 2 forms are characteristic indications of inflammation: pain of the breast, a bright red color with the skin it raises 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 are referred to these forms breast cancer. When tubular carcinoma breast cancers cover as a "skin" of the company's contracting and decreasing in space.

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

For small tumors in the breast, any symptoms arise. The most observant as well as their husbands have the ability to detect tumor site inside the gland accidentally, but inside a large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks in favor of a benign tumor. Signs of malignancy other: a tight knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach a significant size (over three to five cm and often 10-15 cm).

Need to evaluate the surface in the skin in the tumor: the malignant process will probably be observed retraction of the skin, buying inside folds, wrinkles, an indicator of "lemon peel" - a local swelling from the skin within the tumor, might be a direct tumor invasion to skin surface, then it will become a bright red colorization and sprawl as "cauliflower."
