Breast Cancer

Among all cancers in women, he takes the initial place. In most cases, breast cancers develops inside the 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 of the nipple and also the nipple from the field (Paget's disease with the breast). For the nodular cancers are characterized by the node using a diameter up to several centimeters. In some instances, a strong knot, is permeated with whitish layers tissue penetrating in to the surrounding fat, in other people - a soft, juicy on the cut, splits easily. Diffuse prostate type of cancer is roofed for a considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades your skin layer and forms around the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads along the surface of the breast and all sorts of the iron is covered which has a dense shell.

In histological structure are the following forms of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as an varying levels 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 often has the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The reasons for cancer of the breast often are hormonal changes inside body: the entry into menopause, if you have a dynamic restructuring in the hormonal regulation in the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, your body will go through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most tuned in to these changes, the breast tissue begins to dissolve and turn into replaced by fat.

Scientifically established the female hormones estrogen-, plays a vital role within the progression of cancer of the breast. 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 the birth and prolonged breastfeeding (more than 1 year) to reduce the risk of developing breast cancer. On the other hand, abortion bring about hormonal "explosion" in a very woman's body that may trigger the progression of tumors. So far there's no consensus concerning the impact around the development of tumors of hormonal contraceptive drugs, but it is considered that these drugs reduce the risk of developing breast cancer, but increase the chance of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast can cause harmful environmental factors: environmental surroundings, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a group of first-degree relatives with breast cancer (mothers and sisters) probability of making a tumor increasing by more than half - familial forms of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not lead to cancer, but simultaneously, create an unfavorable background due to the development.

The reason for breast cancer will be the connection between radiation, like 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 result in cancer from the breast and female reproductive :, having an excess dimply skin in the body, it becomes a separate endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are many forms from the growth of breast cancer:

- Nodular form, the most common, is characterized by a dense knot of 0.5 to 5 cm or even more, it can be seen as all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" from the breast and skin. For the first couple of forms are characteristic signs of inflammation: pain from the breast, a bright red color of the skin it raises body temperature to 39 degrees C. In view of those symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, that happen to be named and are known as these forms breast cancer. When tubular carcinoma cancer of the breast cover as a "skin" of their contracting and decreasing in proportions.

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

For small tumors with the breast, any symptoms arise. The most observant females and their husbands have the ability to detect tumor site in 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 good knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, can be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (over 3 to 5 cm and often 10-15 cm).

Need to gauge the surface in the skin within the tumor: the malignant process will be observed retraction of the skin, obtaining within the folds, wrinkles, a symptom of "lemon peel" - a local swelling with the skin on the tumor, might be a direct tumor invasion to your skin layer surface, then it is a bright beautiful red colors and sprawl as "cauliflower."
