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, as well as cancer with the nipple along with the nipple with the field (Paget's disease in the breast). For the nodular cancers are characterized by the node creating a diameter up to several centimeters. In some instances, a good knot, is permeated with whitish layers tissue penetrating into the surrounding fatty tissue, in other people - a soft, juicy on the cut, splits easily. Diffuse cancer of prostate is covered for the considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades your skin layer and forms about the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads over the surface with the breast and all the iron is roofed which has a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as varying examples of tissue and cell irregularities, which allowed to distinguish different amount 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 causes of cancer of the breast often are hormonal changes within the body: the entry into menopause, should there be an energetic restructuring with the hormonal regulation in the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, the body is going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most attentive to these changes, the breast growth actually starts to dissolve and turn into replaced by fat.

Scientifically established that this female hormones estrogen-, plays a key role inside the progression of cancer of the breast. The excess hormones inside body generates a favorable background for developing the condition. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (a lot more than one year) to reduce the chance of developing cancer of the breast. On the other hand, abortion bring about hormonal "explosion" inside a woman's body that can trigger the progression of tumors. So far there is absolutely no consensus concerning the impact on the continuing development of tumors of hormonal contraceptive drugs, yet it's considered that these drugs reduce the chance of developing breast cancers, but increase the risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast could cause harmful environmental factors: the environment, along with inflammatory diseases previously deferred breast - mastitis.

In addition, patients having a group of first-degree relatives with breast cancer (mothers and sisters) probability of having 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 bring about cancer, but simultaneously, create an unfavorable background for the development.

The reason behind cancer of the breast could be the effects of radiation, for example 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 with the breast and female reproductive :, by having an excess fatty tissue inside body, it is a different endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

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

- Nodular form, the most frequent, is seen as a dense knot of 0.5 to five cm or more, it can be characterized by all from 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 2 forms are characteristic signs and symptoms of inflammation: pain in the breast, a bright red colorization with 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, which are named and therefore are referred to these forms breast cancers. When tubular carcinoma breast cancer cover like a "skin" of the company's contracting and decreasing in space.

In certain cases, breast cancers 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 with the breast, any symptoms arise. The most observant ladies and their husbands have the ability to detect tumor site within the gland by accident, but inside a large breast to detect small size hard knot. Revealed a knot may be painful when pressed, round, smooth and agile, this speaks in support of a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, could be firmly fixed for the surrounding tissue or skin, usually painless, can reach a significant size (over three to five cm and infrequently 10-15 cm).

Need to gauge the surface with the skin on the tumor: the malignant process will likely be observed retraction in the skin, picking up inside folds, wrinkles, a symptom of "lemon peel" - an area swelling from the skin within the tumor, might be a direct tumor invasion to the skin surface, then it becomes a bright red colorization and sprawl as "cauliflower."
