Breast Cancer

Among all cancers in females, he takes the ultimate place. In most cases, cancer of the breast 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 from the nipple as well as the nipple in the field (Paget's disease from the breast). For the nodular cancers are seen as the node using a diameter as high as several centimeters. In certain cases, a tight knot, is permeated with whitish layers tissue penetrating into the surrounding fatty tissue, in other people - a soft, juicy about the cut, splits easily. Diffuse cancer of prostate is roofed for any considerable distance, the contours from 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 cases, the tumor spreads over the surface from the breast and all the iron is included using a dense shell.

In histological structure are the following varieties of breast cancer:

• 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 degrees of tissue and cell irregularities, which permitted to distinguish different level of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which in turn gets the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The causes of breast cancers often are hormonal changes inside the body: the entry into menopause, when there is an engaged restructuring with the hormonal regulation of 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 from the uterus) are most responsive to these changes, the breast type tissue actually starts to dissolve and turn into replaced by fat.

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

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

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to lead to cancer, but concurrently, create an unfavorable background for the development.

The cause 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 of the breast and female reproductive system, by having an excess fatty tissue within the body, it will become an outside endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are several forms with the growth of breast cancers:

- Nodular form, the most common, is characterized by a dense knot of 0.5 to five cm or higher, it's seen as an all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" from the breast and skin. For the first two forms are characteristic signs of inflammation: pain in 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 diagnosing patients treated for inflammatory diseases, that happen to be named and so are referred to these forms cancer of the breast. When tubular carcinoma cancer of the breast cover like a "skin" of the contracting and decreasing in size.

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

For small tumors of the breast, any symptoms arise. The most observant ladies and their husbands have the ability to detect tumor site within the gland by chance, but in the large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks in support of a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach an important size (over 3 - 5 cm and infrequently 10-15 cm).

Need to gauge the surface of the skin in the tumor: the malignant process will be observed retraction in the skin, collecting in the folds, wrinkles, an indication of "lemon peel" - a neighborhood swelling in the skin in the tumor, may be a direct tumor invasion to your skin surface, then it might be a bright beautiful red colors and sprawl as "cauliflower."
