Breast Cancer

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

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying degrees of tissue and cell irregularities, which allowed to distinguish different a higher level malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which usually has got the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

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

Scientifically established that the female hormones estrogen-, plays an integral role inside the growth and development of cancer of the breast. The excess hormones within the body creates a favorable background for developing the disease. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (more than 1 year) to cut back potential risk of developing cancer of the breast. On the other hand, abortion cause hormonal "explosion" in a woman's body that may trigger the continuing development of tumors. So far there is absolutely no consensus concerning the impact about the development of tumors of hormonal contraceptive drugs, but it's considered that these drugs reduce the risk of developing breast cancers, but increase the chance of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast can cause harmful environmental factors: the surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a category of first-degree relatives with breast cancer (mothers and sisters) chance of having a tumor increasing by more than half - familial varieties of cancer.

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

The reason behind breast cancer may be the connection between radiation, such as 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 bring about cancer in the breast and female reproductive :, with the excess fatty tissue inside body, it becomes an outside 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 some forms from the growth of breast cancer:

- Nodular form, the most frequent, is characterized by a dense knot of 0.5 to cm or maybe more, it is characterized by all in 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 two forms are characteristic indications of inflammation: pain in the breast, a bright beautiful red colors with the skin it raises body temperature to 39 degrees C. In view of the symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, that happen to be named and so are referred to these forms breast cancers. When tubular carcinoma breast cancers cover like a "skin" of the company's contracting and decreasing in proportions.

In certain cases, breast cancers manifests in the form of metastases within the lymph nodes on the affected side, often does not detect the tumor itself - show hidden breast cancers.

For small tumors with the breast, any symptoms arise. The most observant women and their husbands are able to detect tumor site inside the gland unintentionally, 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 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, could be firmly fixed for the surrounding tissue or skin, usually painless, can reach an important size (over 3 to 5 cm and often 10-15 cm).

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