Breast Cancer

Among all cancers in ladies, he takes the ultimate place. In most cases, breast cancers 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, as well as cancer with the nipple and the nipple of the field (Paget's disease from the breast). For the nodular cancers are seen as the node using a diameter up to several centimeters. In certain instances, a strong knot, is permeated with whitish layers tissue penetrating in the surrounding fatty tissue, in other people - a soft, juicy on the cut, splits easily. Diffuse prostate cancer is roofed for the considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads along the surface in the breast and all sorts of the iron is included having a dense shell.

In histological structure are the following kinds of cancer of the breast:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive cancer of the breast can be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is seen as varying degrees of tissue and cell irregularities, which permitted to distinguish different amount of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which usually gets the structure of scirrhus, and also 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 from the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, your body goes through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most understanding of these changes, the breast type tissue actually starts to dissolve and stay replaced by fat.

Scientifically established the female hormones estrogen-, plays an integral role inside growth and development of cancer of the breast. The excess hormones inside the body generates a favorable background for developing the condition. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (over 12 months) to relieve potential risk of developing breast cancers. On the other hand, abortion cause hormonal "explosion" in the woman's body that will trigger the growth and development of tumors. So far there is absolutely no consensus in regards to the impact on the progression of tumors of hormonal contraceptive drugs, yet it's thought that these drugs reduce the potential risk of developing breast cancers, but increase potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancer could cause harmful environmental factors: the planet, in addition to inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not cause cancer, but simultaneously, create an unfavorable background for its development.

The reason behind breast cancer would be the outcomes 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 cause cancer in the breast and female reproductive :, with an excess fat inside body, it becomes a different endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are a couple of forms with the growth of breast cancers:

- Nodular form, the most typical, is seen as a a dense knot of 0.5 to five cm or higher, it's seen as all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" of the breast and skin. For the initial two forms are characteristic signs and symptoms of inflammation: pain in the breast, a bright beautiful red colors with the skin it raises body's temperature to 39 degrees C. In view of the symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, which are named and therefore are described these forms breast cancer. When tubular carcinoma breast cancer cover as being a "skin" of their contracting and decreasing in dimensions.

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

For small tumors from the breast, any symptoms arise. The most observant ladies and their husbands are able to detect tumor site within the gland accidentally, but inside a large breast to detect small size hard knot. Revealed a knot may be painful when pressed, round, smooth and agile, this speaks for 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 for the surrounding tissue or skin, usually painless, can reach a substantial size (greater than 3 - 5 cm and infrequently 10-15 cm).

Need to assess the surface from the skin over the tumor: the malignant process will probably be observed retraction with the skin, picking up inside the folds, wrinkles, an indicator of "lemon peel" - a nearby swelling of the skin on the tumor, is often a direct tumor invasion to your skin layer surface, then it is a bright red color and sprawl as "cauliflower."
