Breast Cancer

Among all cancers in ladies, 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, as well as cancer in the nipple and the nipple from 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 some instances, a good knot, is permeated with whitish layers tissue penetrating into the surrounding fat, on other occasions - a soft, juicy around the cut, splits easily. Diffuse prostate cancer is included to get a considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades the skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads across the surface in the breast and the iron is included using a dense shell.

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

• 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 varying examples of tissue and cell irregularities, which permitted to distinguish different a higher level malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which in turn contains the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes within the body: the entry into menopause, should there be an energetic restructuring in the hormonal regulation with the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, one's body is going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most attentive to these changes, the breast type tissue begins to dissolve and turn into replaced by fat.

Scientifically established that the female hormones estrogen-, plays a vital role inside development of breast cancers. The excess hormones inside body generates a favorable background for developing the illness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (greater than 1 year) to lessen potential risk of developing breast cancers. On the other hand, abortion cause hormonal "explosion" in a very woman's body that could trigger the progression of tumors. So far there isn't any consensus regarding the impact on the progression of tumors of hormonal contraceptive drugs, however it is thought that these drugs reduce the risk of developing cancer of the breast, but increase the risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: the environment, as well as 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) likelihood of creating a tumor increasing by over half - familial kinds of cancer.

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not cause cancer, but at the same time, create an unfavorable background because of its development.

The source of breast cancers may be the connection between radiation, such as irradiation in 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 in the breast and female the reproductive system, with the excess fat within the body, it might be a different 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 cancer:

- Nodular form, the most typical, is characterized by a dense knot of 0.5 to cm or maybe more, 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 any clear boundaries, "spreading" from the breast and skin. For the first two forms are characteristic signs and symptoms of inflammation: pain with the breast, a bright red colorization in the skin it raises temperature to 39 degrees C. In view of such symptoms often occur, and errors in carried out patients treated for inflammatory diseases, that are named and so are known these forms cancer of the breast. When tubular carcinoma breast cancers cover as being a "skin" of the contracting and decreasing in dimensions.

In some cases, breast cancers manifests inside the form of metastases in 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 have the ability to detect tumor site inside the gland unintentionally, 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 in support of a benign tumor. Signs of malignancy other: a tight knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, might be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a tremendous size (more than three to five cm and often 10-15 cm).

Need to evaluate the surface from the skin on the tumor: the malignant process will likely be observed retraction with the skin, obtaining inside folds, wrinkles, an indication of "lemon peel" - a neighborhood swelling of the skin on the tumor, may be a direct tumor invasion to your skin layer surface, then it might be a bright red colorization and sprawl as "cauliflower."
