Breast Cancer

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

In histological structure are the following kinds of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive cancer of the breast could 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 able to distinguish different amount of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which in turn has got the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The factors behind cancer of the breast often are hormonal changes inside body: the entry into menopause, when there is an active restructuring with the hormonal regulation with the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, one's body will go through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most responsive to these changes, the breast type tissue starts to dissolve and turn into replaced by fat.

Scientifically established how the female hormones estrogen-, plays an integral role inside the growth and development of breast cancers. The excess hormones in 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 how the birth and prolonged breastfeeding (over 1 year) to relieve potential risk of developing breast cancer. On the other hand, abortion cause hormonal "explosion" inside a woman's body that will trigger the progression of tumors. So far there's no consensus in regards to the impact around the continuing development of tumors of hormonal contraceptive drugs, however it is thought that these drugs reduce potential risk of developing breast cancers, but increase the chance of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancer may cause harmful environmental factors: the planet, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a group of first-degree relatives with breast cancer (mothers and sisters) probability of having a tumor increasing by more than half - familial kinds of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to cause cancer, but simultaneously, create an unfavorable background due to the development.

The reason for breast cancer will be the outcomes of radiation, including 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 lead to cancer from the breast and female reproductive :, having an excess fat inside body, it might be a different endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are many forms with the growth of breast cancers:

- Nodular form, the most typical, is seen as a a dense knot of 0.5 to cm or more, it really is seen as 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 first two forms are characteristic indications of inflammation: pain with the breast, a bright red colorization 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 therefore are known these forms cancer of the breast. When tubular carcinoma breast cancer cover as a "skin" of the contracting and decreasing in space.

In some instances, breast cancers manifests within the form of metastases inside 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 are able to detect tumor site in the gland by chance, but in a very large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a strong 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 3 to 5 cm and quite often 10-15 cm).

Need to assess the surface from the skin in the tumor: the malignant process will likely be observed retraction with the skin, collecting inside folds, wrinkles, a symptom of "lemon peel" - a nearby swelling of the skin over the tumor, might be a direct tumor invasion to skin surface, then it might be a bright beautiful red colors and sprawl as "cauliflower."
