Breast Cancer

Among all cancers ladies, he takes consumers. In most cases, breast cancers develops in the presence of precancerous changes. This is primarily a benign mammary dysplasia and papilloma ducts.

Breast cancer is represented macroscopically nodular and diffuse forms, along with cancer with the nipple as well as the nipple of the field (Paget's disease of the breast). For the nodular cancers are characterized by the node creating a diameter all the way to several centimeters. In certain instances, a strong knot, is permeated with whitish layers tissue penetrating into the surrounding fatty tissue, on other occasions - a soft, juicy around the cut, splits easily. Diffuse prostate cancer is included for the considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades your skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads across the surface of the breast and many types of the iron is covered having a dense shell.

In histological structure are the following kinds of breast cancers:

• 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 characterized by varying examples 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 usually has got the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The reasons for cancer of the breast often are hormonal changes within the body: the entry into menopause, if you have an engaged restructuring of the hormonal regulation in the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, our bodies goes through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most tuned in to these changes, the breast type tissue starts to dissolve and become replaced by fat.

Scientifically established that the female hormones estrogen-, plays an integral role inside continuing development of breast cancer. The excess hormones inside body produces 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 1 year) to reduce the chance of developing breast cancers. On the other hand, abortion bring about hormonal "explosion" in a woman's body that may trigger the progression of tumors. So far there's no consensus about the impact on the growth and development of tumors of hormonal contraceptive drugs, but it is believed that these drugs reduce the risk of developing breast cancers, but increase the risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancer can cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to cause cancer, but as well, create an unfavorable background for the development.

The cause of breast cancer may be the results of radiation, like 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 cause cancer from the breast and female reproductive system, with an excess fat inside the body, it will become an outside endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are several forms in the growth of breast cancer:

- Nodular form, the most common, is characterized by a dense knot of 0.5 to five cm or more, it can be seen as a all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" from the breast and skin. For the initial two forms are characteristic signs of inflammation: pain in the breast, a bright red colorization in the skin it raises body temperature to 39 degrees C. In view of the symptoms often occur, and errors in carried out patients treated for inflammatory diseases, that are named and therefore are known as these forms breast cancers. When tubular carcinoma breast cancers cover like a "skin" of its contracting and decreasing in dimensions.

In certain cases, breast cancers manifests within the form of metastases in 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 women and their husbands can detect tumor site in the gland by accident, 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 support of a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, could be firmly fixed for the surrounding tissue or skin, usually painless, can reach an important size (over three to five cm and infrequently 10-15 cm).

Need to evaluate the surface of the skin over the tumor: the malignant process will be observed retraction with the skin, obtaining inside the folds, wrinkles, a signal of "lemon peel" - a neighborhood swelling in the skin on the tumor, might be a direct tumor invasion to skin surface, then it is a bright beautiful red colors and sprawl as "cauliflower."
