Breast Cancer

Among all cancers in ladies, he takes consumers. In most cases, cancer of the breast 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, and also cancer of the nipple and the nipple of the field (Paget's disease in the breast). For the nodular cancers are characterized by the node using a diameter all the way to several centimeters. In some instances, a good knot, is permeated with whitish layers tissue penetrating in the surrounding fatty tissue, on other occasions - a soft, juicy around the cut, splits easily. Diffuse cancer of the prostate 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 certain instances, the tumor spreads across the surface with the breast and all the iron is included with a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers may 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 allowed to distinguish different a higher level malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which often has the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The reasons for breast cancers 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 output of progesterone and estrogen, our bodies goes through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most understanding of these changes, the breast growth starts to dissolve and be replaced by fat.

Scientifically established that the female hormones estrogen-, plays an integral role inside the development of breast cancers. The excess hormones inside body generates a favorable background for developing the illness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (over twelve months) to reduce the potential risk of developing breast cancers. On the other hand, abortion result in hormonal "explosion" in a very woman's body that could trigger the development of tumors. So far there is no consensus concerning the impact for the growth and development of tumors of hormonal contraceptive drugs, however it is believed that these drugs reduce the risk of developing breast cancers, but increase the chance of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: environmental surroundings, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients having a group of first-degree relatives with cancer of the breast (mothers and sisters) chance 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 usually do not result in cancer, but as well, create an unfavorable background for its development.

The source of breast cancer would be the effects of radiation, including 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 bring about cancer from the breast and female reproductive :, with an excess fat within the body, it might be an outside endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are a couple of forms in the growth of breast cancers:

- Nodular form, the commonest, is seen as a a dense knot of 0.5 to five cm or higher, it's seen as a all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" of the breast and skin. For the initial two forms are characteristic indications of inflammation: pain of the breast, a bright red color with the skin it raises temperature to 39 degrees C. In view of those symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, which can be named and are referred to these forms breast cancer. When tubular carcinoma cancer of the breast cover like a "skin" of its contracting and decreasing in space.

In some instances, cancer of the breast manifests inside 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 with the breast, any symptoms arise. The most observant females and their husbands can easily detect tumor site inside the gland by accident, but inside a large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a tight knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, can be firmly fixed for the surrounding tissue or skin, usually painless, can reach a substantial size (over 3 - 5 cm and quite often 10-15 cm).

Need to evaluate the surface of the skin within the tumor: the malignant process is going to be observed retraction of the skin, obtaining in the folds, wrinkles, an indicator of "lemon peel" - a nearby swelling of the skin in the tumor, is often a direct tumor invasion to the skin surface, then it becomes a bright red color and sprawl as "cauliflower."
