Breast Cancer

Among all cancers in women, he takes the first 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, and also cancer of the nipple as well as the nipple in the field (Paget's disease with the breast). For the nodular cancers are characterized by the node developing a diameter as high as several centimeters. In certain instances, a decent knot, is permeated with whitish layers tissue penetrating into the surrounding fat, in others - a soft, juicy on the cut, splits easily. Diffuse cancer of prostate is roofed for any considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades the skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads down the surface with the breast and many types of the iron is roofed having a dense shell.

In histological structure will be the following forms 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 seen as varying levels of tissue and cell irregularities, which allowed to distinguish different a higher level malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which often has the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancers often are hormonal changes inside body: the entry into menopause, when there is an active restructuring in the hormonal regulation in the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, your body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most responsive to these changes, the breast growth actually starts to dissolve and stay replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role inside the growth and development of breast cancers. The excess hormones inside body generates a favorable background for developing the condition. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (over 12 months) to cut back potential risk of developing cancer of the breast. On the other hand, abortion lead to hormonal "explosion" in a woman's body that may trigger the growth and development of tumors. So far there is absolutely no consensus in regards to the impact about the growth and development of tumors of hormonal contraceptive drugs, yet it's considered that these drugs reduce potential 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: 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) likelihood of developing a tumor increasing by a lot more than half - familial kinds of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not bring about cancer, but concurrently, create an unfavorable background due to the development.

The cause of breast cancers would be the results of radiation, for example 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 of the breast and female reproductive system, with the excess fatty tissue in the body, it might be an outside endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are several forms in the growth of breast cancer:

- Nodular form, the most typical, is characterized by a dense knot of 0.5 to five cm or maybe more, it's seen as all of 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 first two forms are characteristic signs of inflammation: pain with the breast, a bright red colorization from the skin it raises body temperature to 39 degrees C. In view of these symptoms often occur, and errors in carried out patients treated for inflammatory diseases, which are named and therefore are known as these forms cancer of the breast. When tubular carcinoma breast cancer cover as a "skin" of its contracting and decreasing in size.

In some cases, breast cancers manifests in the form of metastases within the lymph nodes around the affected side, often doesn't detect the tumor itself - show hidden cancer of the breast.

For small tumors with the breast, any symptoms arise. The most observant ladies 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 can 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, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (more than 3 - 5 cm and infrequently 10-15 cm).

Need to assess the surface with the skin within the tumor: the malignant process will likely be observed retraction of the skin, obtaining within the folds, wrinkles, an indication of "lemon peel" - a neighborhood swelling with the skin over the tumor, is often a direct tumor invasion to skin surface, then it will become a bright red colorization and sprawl as "cauliflower."
