Breast Cancer

Among all cancers in women, he takes consumers. In most cases, breast cancer 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, along with cancer from the nipple as well as the nipple from the field (Paget's disease with the breast). For the nodular cancers are seen as an the node having a diameter all the way to several centimeters. In certain instances, a strong knot, is permeated with whitish layers tissue penetrating to the surrounding dimply skin, in others - a soft, juicy about the cut, splits easily. Diffuse prostate type of cancer is covered for the 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 some cases, the tumor spreads down the surface from the breast and the iron is roofed having a dense shell.

In histological structure are the following types of breast cancer:

• 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 allowed to distinguish different level of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which will gets the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The reasons for cancer of the breast often are hormonal changes inside body: the entry into menopause, should there be a dynamic restructuring in the hormonal regulation in the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, our bodies will go through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most responsive to these changes, the breast tissue actually starts to dissolve and turn into replaced by fat.

Scientifically established the female hormones estrogen-, plays an important role in the growth and development of breast cancer. The excess hormones in the body generates a favorable background for developing the condition. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (a lot more than 1 year) to relieve the chance of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" inside a woman's body that will trigger the growth and development of tumors. So far there is no consensus in regards to the impact around the development of tumors of hormonal contraceptive drugs, but it is thought that these drugs reduce the chance of developing breast cancer, but increase the chance of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancer may cause harmful environmental factors: the planet, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a family of first-degree relatives with cancer of the breast (mothers and sisters) risk of creating a tumor increasing by a lot more than half - familial types of cancer.

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to cause cancer, but as well, create an unfavorable background because of its development.

The reason for cancer of the breast may be the effects of radiation, such as irradiation of 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 the reproductive system, with the excess fat within the body, it is a different endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are many forms of the growth of breast cancer:

- Nodular form, the most common, is seen as a a dense knot of 0.5 to five cm or even more, it's seen as an all with 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 2 forms are characteristic warning signs of inflammation: pain of the breast, a bright beautiful red colors of the skin it raises body's temperature to 39 degrees C. In view of these symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that happen to be named and so are described these forms cancer of the breast. When tubular carcinoma cancer of the breast cover as a "skin" of the contracting and decreasing in space.

In some cases, breast cancers manifests inside the form of metastases inside the lymph nodes around the affected side, often doesn't detect the tumor itself - show hidden breast cancer.

For small tumors in the breast, any symptoms arise. The most observant ladies and their husbands have the ability to detect tumor site in the gland by accident, but in a large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, can be firmly fixed on the surrounding tissue or skin, usually painless, can reach an important size (a lot more than 3 to 5 cm and sometimes 10-15 cm).

Need to assess the surface of the skin on the tumor: the malignant process will probably be observed retraction of the skin, picking up inside folds, wrinkles, a symptom of "lemon peel" - a local swelling with the skin in the tumor, may be a direct tumor invasion to your skin layer surface, then it is a bright red color and sprawl as "cauliflower."
