Breast Cancer

Among all cancers ladies, he takes consumers. In most cases, breast cancer 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, and also cancer with the nipple along with the nipple from the field (Paget's disease with the breast). For the nodular cancers are seen as an the node developing a diameter of up to several centimeters. In certain cases, a tight knot, is permeated with whitish layers tissue penetrating into the surrounding fat, in others - a soft, juicy on the cut, splits easily. Diffuse cancer of the prostate is covered for a considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades skin and forms for the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads across the surface from the breast and all sorts of the iron is included with a dense shell.

In histological structure would be the following forms of cancer of the breast:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

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

Causes of Breast Cancer.

The causes of breast cancers often are hormonal changes inside the body: the entry into menopause, when there is an active restructuring in the hormonal regulation with the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, our bodies is going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most tuned in to these changes, the breast type tissue begins to dissolve and turn into replaced by fat.

Scientifically established the female hormones estrogen-, plays an integral role within the progression of cancer of the breast. The excess hormones inside body generates a favorable background for developing the disease. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (a lot more than one year) to cut back the chance of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" in a very woman's body that can trigger the growth and development of tumors. So far there isn't any consensus about the impact for the development of tumors of hormonal contraceptive drugs, yet it's belief that these drugs reduce the potential risk of developing breast cancers, but increase the chance of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancers may cause harmful environmental factors: the environment, 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) risk of having a tumor increasing by a lot more than half - familial types of cancer.

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

The reason for cancer of the breast could be the connection between radiation, including 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 of the breast and female the reproductive system, by having an excess fatty tissue inside the body, it is a different endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are a couple of forms of the growth of cancer of the breast:

- Nodular form, the most frequent, is seen as an a dense knot of 0.5 to cm or maybe more, it really is characterized by all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" in the breast and skin. For the first couple of forms are characteristic signs and symptoms of inflammation: pain in the breast, a bright red color of the skin it raises temperature to 39 degrees C. In view of these symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that are named and they are referred to these forms breast cancer. When tubular carcinoma cancer of the breast cover being a "skin" of the company's contracting and decreasing in proportions.

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

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 accident, but in 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 strong knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, may be firmly fixed on the surrounding tissue or skin, usually painless, can reach a tremendous size (a lot more than three to five cm and sometimes 10-15 cm).

Need to evaluate the surface with the skin in the tumor: the malignant process will be observed retraction in the skin, collecting inside folds, wrinkles, an indication of "lemon peel" - a neighborhood swelling with the skin within the tumor, is often a direct tumor invasion to the skin surface, then it will become a bright red color and sprawl as "cauliflower."
