Breast Cancer

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

In histological structure include the following kinds of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as a varying examples of tissue and cell irregularities, which allowed to distinguish different level of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which will has got the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes inside body: the entry into menopause, should there be a dynamic restructuring from the hormonal regulation with the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, the body goes through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most tuned in to these changes, the breast growth starts to dissolve and turn into replaced by fat.

Scientifically established how the female hormones estrogen-, plays a key role within the continuing development of cancer of the breast. The excess hormones within the body produces a favorable background for developing the disease. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (more than 12 months) to lessen potential risk of developing breast cancer. On the other hand, abortion bring about hormonal "explosion" inside a woman's body that can trigger the progression of tumors. So far there is no consensus concerning the impact around the continuing development of tumors of hormonal contraceptive drugs, but it's thought that these drugs reduce the potential risk of developing breast cancers, but increase the potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancers may cause harmful environmental factors: environmental surroundings, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a category of first-degree relatives with cancer of the breast (mothers and sisters) probability of having a tumor increasing by greater than half - familial kinds of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not cause cancer, but as well, create an unfavorable background due to the development.

The reason behind breast cancers would be the connection between 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 result in cancer with the breast and female reproductive :, by having an excess fat in the body, it will become 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 several forms from the growth of cancer of the breast:

- Nodular form, the most typical, is characterized by a dense knot of 0.5 to cm or higher, it can be seen as a all of the following symptoms;

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

In certain cases, cancer of the breast manifests inside form of metastases inside the lymph nodes about the affected side, often fails to detect the tumor itself - show hidden breast cancer.

For small tumors from the breast, any symptoms arise. The most observant as well as their husbands can easily detect tumor site inside gland unintentionally, but in a large breast to detect small size hard knot. Revealed a knot may be painful when pressed, round, smooth and agile, this speaks in favor of a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, may be firmly fixed on the surrounding tissue or skin, usually painless, can reach a substantial size (greater than three to five cm and quite often 10-15 cm).

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