Breast Cancer

Among all cancers 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, along with cancer from the nipple along with the nipple from the field (Paget's disease of the breast). For the nodular cancers are seen as the node having a diameter as high as several centimeters. In some instances, a decent knot, is permeated with whitish layers tissue penetrating in to the surrounding fat, on other occasions - a soft, juicy around the cut, splits easily. Diffuse prostate cancer is included for a considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades the skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads over the surface from the breast and all sorts of the iron is covered having a dense shell.

In histological structure are the following varieties of breast cancer:

• 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 degrees of tissue and cell irregularities, which able to distinguish different degree of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which often has got the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes inside body: the entry into menopause, if you have an engaged restructuring with the hormonal regulation from the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, your body is going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most understanding of these changes, the breast growth actually starts to dissolve and turn into replaced by fat.

Scientifically established the female hormones estrogen-, plays an important role in the development of breast cancer. The excess hormones inside 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 the birth and prolonged breastfeeding (greater than twelve months) to relieve the chance of developing breast cancer. On the other hand, abortion result in hormonal "explosion" in a woman's body that could trigger the growth and development of tumors. So far there isn't any consensus concerning the impact on the development of tumors of hormonal contraceptive drugs, however it is believed that these drugs reduce potential risk of developing breast cancer, but increase the chance of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: environmental surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a category of first-degree relatives with breast cancer (mothers and sisters) risk of developing a tumor increasing by over half - familial kinds of cancer.

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't bring about cancer, but concurrently, create an unfavorable background because of its development.

The reason behind cancer of the breast will be the effects of radiation, for example 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 cause cancer from the breast and female reproductive :, with an excess fat in the body, it is another endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are some forms of the growth of cancer of the breast:

- Nodular form, the commonest, is characterized by a dense knot of 0.5 to five cm or maybe more, it really is seen as a all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" from the breast and skin. For the first two forms are characteristic warning 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, which can be named and so are referred to these forms cancer of the breast. When tubular carcinoma cancer of the breast cover like a "skin" of the contracting and decreasing in dimensions.

In some cases, breast cancers manifests inside form of metastases within the lymph nodes on the affected side, often fails to 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 easily detect tumor site inside the gland by chance, but in the large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks for a benign tumor. Signs of malignancy other: a tight knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (greater than three to five cm and sometimes 10-15 cm).

Need to assess the surface of the skin within the tumor: the malignant process is going to be observed retraction in the skin, obtaining inside folds, wrinkles, an indication of "lemon peel" - a nearby swelling of the skin over the tumor, may be a direct tumor invasion to your skin surface, then it becomes a bright beautiful red colors and sprawl as "cauliflower."
