Breast Cancer

Among all cancers ladies, he takes the first place. In most cases, breast cancers develops in the presence of precancerous changes. This is primarily a benign mammary dysplasia and papilloma ducts.

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

In histological structure include the following kinds of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as varying levels of tissue and cell irregularities, which able to distinguish different degree of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which will has the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The reasons behind cancer of the breast often are hormonal changes inside the body: the entry into menopause, should there be an active restructuring from the hormonal regulation from the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, the body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most attentive to these changes, the breast growth begins to dissolve and stay replaced by fat.

Scientifically established that the female hormones estrogen-, plays an integral role inside growth and development of cancer of the breast. The excess hormones inside body creates a favorable background for developing the disease. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (greater than 1 year) to relieve the risk of developing breast cancers. On the other hand, abortion result in hormonal "explosion" in the woman's body that will trigger the continuing development of tumors. So far there's no consensus regarding the impact about the growth and development of tumors of hormonal contraceptive drugs, but it is thought that these drugs reduce potential risk of developing breast cancer, but increase the chance of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancer might cause harmful environmental factors: environmental surroundings, along with inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a group of first-degree relatives with breast cancer (mothers and sisters) chance of creating a tumor increasing by greater than half - familial types of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to bring about cancer, but concurrently, create an unfavorable background for its development.

The reason for breast cancers may be the outcomes of radiation, including irradiation from 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 the reproductive system, with an excess dimply skin inside the body, it becomes an outside endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are many forms with the growth of cancer of the breast:

- Nodular form, the most typical, is seen as an a dense knot of 0.5 to cm or higher, it can be seen as a all in 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 and symptoms of inflammation: pain from 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 diagnosis of patients treated for inflammatory diseases, which can be named and they are referred to these forms breast cancer. When tubular carcinoma breast cancers cover like a "skin" of the company's contracting and decreasing in proportions.

In certain instances, breast cancers manifests in the form of metastases inside lymph nodes about the affected side, often does not detect the tumor itself - show hidden breast cancers.

For small tumors from the breast, any symptoms arise. The most observant females and their husbands are able to detect tumor site within the gland unintentionally, but inside a large breast to detect small size hard knot. Revealed a knot can 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, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (more than 3 to 5 cm and often 10-15 cm).

Need to gauge the surface of the skin in the tumor: the malignant process is going to be observed retraction in the skin, buying within the folds, wrinkles, an indicator of "lemon peel" - an area swelling of the skin on the tumor, is often a direct tumor invasion to your skin layer surface, then it might be a bright beautiful red colors and sprawl as "cauliflower."
