Breast Cancer

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

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

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers can be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is characterized by varying degrees of tissue and cell irregularities, which in a position to distinguish different degree of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which often contains the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The causes of cancer of the breast often are hormonal changes in the body: the entry into menopause, when there is an engaged restructuring in the hormonal regulation from the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, one's body is going through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most attentive to these changes, the breast tissue starts to dissolve and stay replaced by fat.

Scientifically established the female hormones estrogen-, plays an important role within the progression of breast cancer. The excess hormones within 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 that this birth and prolonged breastfeeding (over one year) to relieve potential risk of developing breast cancer. On the other hand, abortion lead to hormonal "explosion" in the woman's body that could trigger the development of tumors. So far there is absolutely no consensus about the impact around the continuing development of tumors of hormonal contraceptive drugs, yet it's believed that these drugs reduce the risk of developing breast cancers, but increase potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients having a family of first-degree relatives with cancer of the breast (mothers and sisters) risk of developing a tumor increasing by over half - familial forms of cancer.

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

The reason behind breast cancers would be the outcomes of radiation, including irradiation from 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 reproductive system, with the excess dimply skin inside body, it is a different endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are some forms with the growth of breast cancers:

- Nodular form, the most frequent, is seen as an a dense knot of 0.5 to cm or maybe more, it can be seen as a all from 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 two forms are characteristic warning signs of inflammation: pain of the breast, a bright red colorization of the skin it raises temperature to 39 degrees C. In view of the symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, that are named and therefore are known as these forms cancer of the breast. When tubular carcinoma cancer of the breast cover like a "skin" of their contracting and decreasing in space.

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

For small tumors in the breast, any symptoms arise. The most observant as well as their husbands can detect tumor site in the gland by chance, but in 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 decent knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, might be firmly fixed on the surrounding tissue or skin, usually painless, can reach a tremendous size (greater than three to five cm and often 10-15 cm).

Need to gauge the surface from the skin within the tumor: the malignant process is going to be observed retraction of the skin, obtaining in the folds, wrinkles, a symptom of "lemon peel" - a neighborhood swelling of the skin over the tumor, may be a direct tumor invasion to the skin surface, then it will become a bright beautiful red colors and sprawl as "cauliflower."
