Breast Cancer

Among all cancers in females, he takes the initial place. 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, in addition to cancer with the nipple and also the nipple of the field (Paget's disease of the breast). For the nodular cancers are seen as a the node having a diameter all the way to several centimeters. In certain instances, a tight knot, is permeated with whitish layers tissue penetrating in to the surrounding fatty tissue, in other people - a soft, juicy around the cut, splits easily. Diffuse prostate type of cancer is roofed for any considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades your skin layer and forms on the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads over the surface in the breast and all sorts of the iron is included with a dense shell.

In histological structure include the following kinds of cancer of the breast:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as an varying examples of tissue and cell irregularities, which permitted to distinguish different a higher level malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which in turn gets the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

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

Scientifically established the female hormones estrogen-, plays an important role in the development of breast cancer. The excess hormones within the 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 that the birth and prolonged breastfeeding (over 12 months) to cut back the potential risk of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" inside a woman's body that could trigger the growth and development of tumors. So far there isn't any consensus regarding the impact around the continuing development of tumors of hormonal contraceptive drugs, yet it's thought that these drugs reduce the potential 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 breast cancer can cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a family of first-degree relatives with cancer of the breast (mothers and sisters) probability of having a tumor increasing by over half - familial varieties of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not result in cancer, but concurrently, create an unfavorable background because of its development.

The reason behind cancer of the breast could be the outcomes of radiation, such as irradiation with 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 reproductive :, having an excess fat inside the body, it is an outside endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are several forms from the growth of breast cancers:

- Nodular form, the most common, is seen as an a dense knot of 0.5 to 5 cm or maybe more, it really is seen as a all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" with the breast and skin. For the first 2 forms are characteristic warning signs of inflammation: pain of the breast, a bright red colorization from the skin it raises temperature to 39 degrees C. In view of the symptoms often occur, and errors in carried out 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 company's contracting and decreasing in dimensions.

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

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

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