Breast Cancer

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

In histological structure are the following varieties of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as varying examples of tissue and cell irregularities, which permitted to distinguish different level of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which in turn has the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes inside body: the entry into menopause, if you find an engaged restructuring in the hormonal regulation of the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, one's body will go through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most understanding of these changes, the breast tissue actually starts to dissolve and be replaced by fat.

Scientifically established that this female hormones estrogen-, plays an integral role within the growth and development of cancer of the breast. The excess hormones in the body creates a favorable background for developing the sickness. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (a lot more than twelve months) to lessen the chance of developing cancer of the breast. On the other hand, abortion bring about hormonal "explosion" in the woman's body that will trigger the progression of tumors. So far there is absolutely no consensus regarding the impact around the progression of tumors of hormonal contraceptive drugs, but it's thought that these drugs reduce the potential risk of developing breast cancer, but increase the potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancer could cause harmful environmental factors: the environment, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a category of first-degree relatives with breast cancer (mothers and sisters) chance of having a tumor increasing by greater than half - familial types of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not bring about cancer, but at the same time, create an unfavorable background for its development.

The reason behind breast cancers would be the results of radiation, such as 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 in the breast and female reproductive :, by having an excess dimply skin within the body, it is another 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 frequent, is seen as a dense knot of 0.5 to cm or more, it's seen as a all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" in the breast and skin. For the initial two forms are characteristic indications of inflammation: pain in the breast, a bright beautiful red colors with the skin it raises body temperature to 39 degrees C. In view of these symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, that happen to be named and so are referred to these forms cancer of the breast. When tubular carcinoma breast cancers cover as being a "skin" of its contracting and decreasing in space.

In certain instances, breast cancer manifests inside the form of metastases within the lymph nodes on the affected side, often doesn't detect the tumor itself - show hidden breast cancer.

For small tumors with the breast, any symptoms arise. The most observant females and their husbands can easily detect tumor site within the gland unintentionally, but in the large breast to detect small size hard knot. Revealed a knot may 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 can be stationary or slightly shifted, can be firmly fixed for the surrounding tissue or skin, usually painless, can reach a tremendous size (more than 3 to 5 cm and quite often 10-15 cm).

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