Breast Cancer

Among all cancers ladies, he takes the ultimate place. In most cases, cancer of the breast develops within 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 along with the nipple with the field (Paget's disease with the breast). For the nodular cancers are seen as an the node developing a diameter as high as several centimeters. In certain cases, a decent knot, is permeated with whitish layers tissue penetrating into the surrounding dimply skin, on other occasions - a soft, juicy for the cut, splits easily. Diffuse prostate type of cancer is roofed for any considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades the skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads across the surface with the breast and many types of the iron is covered having a dense shell.

In histological structure will be the following kinds of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as a varying levels of tissue and cell irregularities, which allowed to distinguish different degree of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which in turn gets the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancer often are hormonal changes within the body: the entry into menopause, when there is an engaged restructuring from the hormonal regulation from the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, one's body will go through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most tuned in to these changes, the breast growth starts to dissolve and become replaced by fat.

Scientifically established that this female hormones estrogen-, plays a key role in the growth and development 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 the birth and prolonged breastfeeding (greater than one year) to reduce the potential risk of developing cancer of the breast. On the other hand, abortion bring about hormonal "explosion" inside a woman's body that will trigger the development of tumors. So far there is absolutely no consensus in regards to the impact for the progression of tumors of hormonal contraceptive drugs, however it is thought that these drugs reduce the risk of developing breast cancer, but increase the chance of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: the environment, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients using a group of first-degree relatives with breast cancers (mothers and sisters) risk of having a tumor increasing by a lot more than half - familial kinds of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not cause cancer, but concurrently, create an unfavorable background due to the development.

The cause of cancer of the breast may be the outcomes of radiation, like 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 from the breast and female reproductive :, with the excess fat within the body, it becomes a separate endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are several forms with the growth of breast cancers:

- Nodular form, the most typical, is seen as a a dense knot of 0.5 to cm or even more, it's seen as a all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without 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 of the skin it raises body temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that happen to be named and are described these forms cancer of the breast. When tubular carcinoma cancer of the breast cover like a "skin" of their contracting and decreasing in proportions.

Preoperative breast MRI associated with more testing and mastectomies

In some instances, cancer of the breast manifests inside form of metastases within the lymph nodes about the affected side, often doesn't detect the tumor itself - show hidden breast cancers.

For small tumors from the breast, any symptoms arise. The most observant as well as their husbands are able to detect tumor site within the gland by chance, but in the 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 good knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, may be firmly fixed to the surrounding tissue or skin, usually painless, can reach a significant size (a lot more than 3 to 5 cm and quite often 10-15 cm).

Need to assess the surface with the skin in the tumor: the malignant process is going to be observed retraction in the skin, collecting inside folds, wrinkles, a symptom of "lemon peel" - a nearby swelling from the skin over the tumor, might be a direct tumor invasion to your skin layer surface, then it is a bright red color and sprawl as "cauliflower."
