Breast Cancer

Among all cancers in females, he takes the ultimate place. In most cases, breast cancer develops inside 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 along with the nipple with the field (Paget's disease from the breast). For the nodular cancers are seen as an the node using a diameter up to several centimeters. In some cases, a strong knot, is permeated with whitish layers tissue penetrating into the surrounding fat, in other people - a soft, juicy about the cut, splits easily. Diffuse prostate cancer is covered to get a considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades skin and forms for the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads across the surface in the breast and many types of the iron is covered with a dense shell.

In histological structure are the following forms of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as an varying levels of tissue and cell irregularities, which permitted to distinguish different level of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which will gets the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes inside body: the entry into menopause, if you find an active restructuring of the hormonal regulation from the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, one's body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most attentive to these changes, the breast tissue actually starts to dissolve and be replaced by fat.

Scientifically established that this female hormones estrogen-, plays a vital role within the progression of breast cancer. The excess hormones inside the body generates 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 potential risk of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" inside a woman's body that can trigger the progression of tumors. So far there's no consensus in regards to the impact on the development of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce the risk of developing cancer of the breast, but increase the potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancers can cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a group of first-degree relatives with cancer of the breast (mothers and sisters) risk of creating 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 lead to cancer, but concurrently, create an unfavorable background because of its development.

The reason for breast cancers may be the outcomes of radiation, like 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 bring about cancer from the breast and female reproductive system, by having an excess fatty tissue within the body, it will become a different endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are a couple of forms in the growth of breast cancer:

- Nodular form, the commonest, is seen as a a dense knot of 0.5 to 5 cm or maybe more, it can be seen as all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" in the breast and skin. For the first 2 forms are characteristic signs and symptoms of inflammation: pain in the breast, a bright red color of 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, that happen to be named and so are referred to these forms cancer of the breast. When tubular carcinoma breast cancers cover like a "skin" of the contracting and decreasing in space.

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

For small tumors in the breast, any symptoms arise. The most observant ladies and their husbands can detect tumor site within the gland by accident, but in a very large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks in support of a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, can be firmly fixed for the surrounding tissue or skin, usually painless, can reach a significant size (greater than 3 to 5 cm and quite often 10-15 cm).

Need to evaluate the surface in the skin on the tumor: the malignant process will likely be observed retraction of the skin, buying inside folds, wrinkles, an indication of "lemon peel" - an area swelling from the skin in the tumor, may be a direct tumor invasion to the skin surface, then it will become a bright beautiful red colors and sprawl as "cauliflower."
