Breast Cancer

Among all cancers ladies, he takes the ultimate place. In most cases, cancer of the breast develops within 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 and the nipple with the field (Paget's disease in the breast). For the nodular cancers are seen as a the node developing a diameter as high as several centimeters. In certain instances, a decent knot, is permeated with whitish layers tissue penetrating in the surrounding fatty tissue, on other occasions - a soft, juicy for the cut, splits easily. Diffuse prostate type of cancer is included to get a considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades your skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads along the surface from the breast and many types of the iron is covered with a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers could 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 able to distinguish different degree of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which usually contains the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancer often are hormonal changes inside the body: the entry into menopause, if you have a dynamic restructuring in the hormonal regulation in the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, our bodies is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most understanding of these changes, the breast type tissue actually starts to dissolve and stay replaced by fat.

Scientifically established that this female hormones estrogen-, plays a vital role inside the continuing development of cancer of the breast. The excess hormones inside the body creates a favorable background for developing the illness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (more than one year) to cut back the risk of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" in a very woman's body that will trigger the growth and development of tumors. So far there is no consensus in regards to the impact around the progression of tumors of hormonal contraceptive drugs, yet it's belief that these drugs reduce the risk of developing breast cancer, but increase the risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast may cause harmful environmental factors: environmental surroundings, in addition to inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't lead to cancer, but as well, create an unfavorable background for its development.

The cause of breast cancers would be the connection between 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 lead to cancer with the breast and female reproductive :, by having an excess dimply skin inside the body, it might be a separate 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 many forms of the growth of breast cancers:

- Nodular form, the commonest, is seen as an a dense knot of 0.5 to cm or higher, it really is seen as an all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" from the breast and skin. For the first 2 forms are characteristic warning signs of inflammation: pain with the breast, a bright red colorization of the skin it raises temperature to 39 degrees C. In view of these symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, which can be named and are described these forms breast cancer. When tubular carcinoma breast cancer cover like a "skin" of their contracting and decreasing in proportions.

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

For small tumors in the breast, any symptoms arise. The most observant females and their husbands are able to detect tumor site inside the gland by chance, but in a very 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 good 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 substantial size (greater than 3 to 5 cm and quite often 10-15 cm).

Need to evaluate the surface of the skin within the tumor: the malignant process will likely be observed retraction in the skin, picking up within the folds, wrinkles, a symptom of "lemon peel" - a local swelling with the skin in the tumor, is often a direct tumor invasion to skin surface, then it might be a bright red color and sprawl as "cauliflower."
