Breast Cancer

Among all cancers ladies, he takes consumers. In most cases, breast cancer develops inside 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 in the nipple and the nipple with the field (Paget's disease from the breast). For the nodular cancers are seen as an the node using a diameter of up to several centimeters. In certain cases, a good knot, is permeated with whitish layers tissue penetrating to the surrounding fatty tissue, on other occasions - a soft, juicy for the cut, splits easily. Diffuse prostate type of cancer is roofed for the considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades the skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads over the surface with the breast and the iron is included having a dense shell.

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

• 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 levels of tissue and cell irregularities, which allowed to distinguish different amount of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which in turn has got the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancers often are hormonal changes within the body: the entry into menopause, if you have an energetic restructuring in the hormonal regulation with the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, our bodies is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most tuned in to these changes, the breast tissue actually starts to dissolve and be replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role in the continuing development of breast cancers. The excess hormones within the body creates a favorable background for developing the condition. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (over twelve months) to relieve the potential risk of developing cancer of the breast. On the other hand, abortion bring about hormonal "explosion" in a woman's body that could trigger the growth and development of tumors. So far there isn't any consensus concerning the impact around the continuing development of tumors of hormonal contraceptive drugs, however it is thought that these drugs reduce the chance of developing breast cancers, but increase the potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancers may cause harmful environmental factors: the surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a category of first-degree relatives with breast cancer (mothers and sisters) likelihood of developing a tumor increasing by over half - familial varieties of cancer.

Benign breast diseases including 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 breast cancer will be the outcomes of radiation, for example 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 of the breast and female reproductive system, by having an excess fatty tissue in the body, it will become another 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 several forms from the growth of cancer of the breast:

- Nodular form, the most frequent, is seen as a a dense knot of 0.5 to five cm or higher, it is seen as a all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" in the breast and skin. For the first couple of forms are characteristic signs 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, that happen to be named and therefore are known as these forms breast cancer. When tubular carcinoma breast cancer cover being a "skin" of its contracting and decreasing in size.

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

For small tumors from the breast, any symptoms arise. The most observant women and their husbands can detect tumor site in the gland by chance, but in a very 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 strong knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, might be firmly fixed towards the surrounding tissue or skin, usually painless, can reach an important size (greater than three to five cm and sometimes 10-15 cm).

Need to evaluate the surface from the skin over the tumor: the malignant process will likely be observed retraction in the skin, collecting within the folds, wrinkles, an indication of "lemon peel" - a local swelling with the skin in the tumor, may be a direct tumor invasion to your skin surface, then it will become a bright red colorization and sprawl as "cauliflower."
