Breast Cancer

Among all cancers ladies, he takes the initial place. In most cases, breast cancer 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 from the nipple and also the nipple from the field (Paget's disease in the breast). For the nodular cancers are characterized by the node creating a diameter all the way to several centimeters. In some instances, a strong knot, is permeated with whitish layers tissue penetrating into the surrounding fatty tissue, on other occasions - a soft, juicy about the cut, splits easily. Diffuse cancer of the prostate is covered for the considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades your skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads down the surface in the breast and many types of the iron is covered with a dense shell.

In histological structure will be the following varieties 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 varying levels of tissue and cell irregularities, which able to distinguish different level of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which in turn contains the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes inside the body: the entry into menopause, if you have a dynamic restructuring from the hormonal regulation in the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, the body is going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most tuned in to these changes, the breast growth actually starts to dissolve and turn into replaced by fat.

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

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't bring about cancer, but concurrently, create an unfavorable background for its development.

The reason for breast cancer will be the results of radiation, such as irradiation in 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, having an excess fatty tissue in the body, it becomes another endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are some forms in the growth of breast cancer:

- Nodular form, the commonest, is characterized by a dense knot of 0.5 to five cm or even more, it is characterized by all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" of the breast and skin. For the first 2 forms are characteristic signs of inflammation: pain from the breast, a bright beautiful red colors of the skin it raises body temperature to 39 degrees C. In view of these symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, which can be named and so are known as these forms cancer of the breast. When tubular carcinoma breast cancers cover as being a "skin" of the contracting and decreasing in dimensions.

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

For small tumors of the breast, any symptoms arise. The most observant ladies and their husbands can easily detect tumor site inside 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 and only a benign tumor. Signs of malignancy other: a decent 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 (more than 3 to 5 cm and sometimes 10-15 cm).

Need to evaluate the surface in the skin on the tumor: the malignant process will likely be observed retraction from the skin, obtaining inside the folds, wrinkles, an indicator of "lemon peel" - a neighborhood swelling from the skin over the tumor, is often a direct tumor invasion to the skin surface, then it becomes a bright red color and sprawl as "cauliflower."
