Breast Cancer

Among all cancers ladies, he takes the ultimate place. 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, along with cancer from the nipple and also the nipple from the field (Paget's disease of the breast). For the nodular cancers are seen as an the node developing a diameter up to several centimeters. In some instances, a tight knot, is permeated with whitish layers tissue penetrating to the surrounding fatty tissue, on other occasions - a soft, juicy about the cut, splits easily. Diffuse prostate type of cancer is covered for any considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades the skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads over the surface of the breast and the iron is covered with a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as varying levels of tissue and cell irregularities, which permitted to distinguish different level of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which often gets the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The factors behind cancer of the breast often are hormonal changes in the body: the entry into menopause, should there be an active restructuring with the hormonal regulation with the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, the body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most tuned in to these changes, the breast growth begins to dissolve and turn into replaced by fat.

Scientifically established that this female hormones estrogen-, plays a key role within the progression of breast cancers. The excess hormones inside body produces a favorable background for developing the disease. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (over one year) to relieve the chance of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" in the woman's body that can trigger the growth and development of tumors. So far there is absolutely no consensus in regards to the impact for the progression of tumors of hormonal contraceptive drugs, but it is thought that these drugs reduce potential risk of developing breast cancers, but increase the risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: environmental surroundings, in addition to inflammatory diseases previously deferred breast - mastitis.

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

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not bring about cancer, but at the same time, create an unfavorable background due to the development.

The cause of breast cancers would be the results of radiation, for example irradiation from 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 of the breast and female reproductive :, with an excess dimply skin inside 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 many forms in the growth of breast cancer:

- Nodular form, the most typical, is characterized by a dense knot of 0.5 to five cm or more, it's characterized by all from the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" with the breast and skin. For the first couple of forms are characteristic indications of inflammation: pain from the breast, a bright red colorization of the skin it raises body's 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 so are referred to these forms cancer of the breast. When tubular carcinoma breast cancers cover as a "skin" of its contracting and decreasing in dimensions.

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

For small tumors of the breast, any symptoms arise. The most observant ladies and their husbands are able to detect tumor site inside the gland by accident, but in a very large breast to detect small size hard knot. Revealed a knot could 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 can be stationary or slightly shifted, can be firmly fixed for the surrounding tissue or skin, usually painless, can reach a substantial size (greater than 3 to 5 cm and quite often 10-15 cm).

Need to assess the surface from the skin in the tumor: the malignant process will likely be observed retraction from the skin, collecting inside folds, wrinkles, a signal of "lemon peel" - a local swelling in the skin over the tumor, is often a direct tumor invasion to your skin surface, then it is a bright red colorization and sprawl as "cauliflower."
