Breast Cancer

Among all cancers in women, he takes the ultimate 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, as well as cancer of the nipple and the nipple of the field (Paget's disease of the breast). For the nodular cancers are seen as a the node developing a diameter up to several centimeters. In some instances, a strong knot, is permeated with whitish layers tissue penetrating to the surrounding fat, in others - a soft, juicy on the cut, splits easily. Diffuse cancer of prostate is included for any considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades your skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads along the surface of the breast and all the iron is included which has a dense shell.

In histological structure will be the following types of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying degrees of tissue and cell irregularities, which in a position to distinguish different level of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which will gets the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The reasons for breast cancer often are hormonal changes within the body: the entry into menopause, if you have a dynamic restructuring with the hormonal regulation with the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, our bodies is going through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most responsive to these changes, the breast tissue begins to dissolve and be replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role inside progression of breast cancers. The excess hormones in the body generates a favorable background for developing the sickness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (over twelve months) to lessen potential risk of developing breast cancer. On the other hand, abortion result in hormonal "explosion" in the woman's body that may trigger the development of tumors. So far there isn't any consensus regarding the impact around the growth and development of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce the risk of developing cancer of the breast, but increase the risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast can cause harmful environmental factors: the environment, and also inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't lead to cancer, but at the same time, create an unfavorable background because of its development.

The reason behind cancer of the breast would be the connection between 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 lead to cancer from the breast and female reproductive system, by having an excess fat in the body, it is another endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are some forms with the growth of breast cancers:

- Nodular form, the most common, is seen as an a dense knot of 0.5 to cm or higher, it really is seen as all from the following symptoms;

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

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

For small tumors from the breast, any symptoms arise. The most observant women and their husbands have the ability to detect tumor site within the gland accidentally, 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 for a benign tumor. Signs of malignancy other: a decent 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 tremendous size (over 3 - 5 cm and sometimes 10-15 cm).

Need to assess the surface from the skin over the tumor: the malignant process is going to be observed retraction with the skin, obtaining inside folds, wrinkles, a symptom of "lemon peel" - a neighborhood swelling from the skin over the tumor, is often a direct tumor invasion to your skin layer surface, then it is a bright beautiful red colors and sprawl as "cauliflower."
