Breast Cancer

Among all cancers ladies, he takes the first place. In most cases, breast cancer 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, in addition to cancer with the nipple and also the nipple with the field (Paget's disease from the breast). For the nodular cancers are seen as a the node using a diameter all the way to several centimeters. In some instances, a strong knot, is permeated with whitish layers tissue penetrating in to the surrounding fat, in other people - a soft, juicy around the cut, splits easily. Diffuse prostate type of cancer is roofed for a considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads over the surface of the breast and many types of the iron is roofed with a dense shell.

In histological structure are the following forms of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

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

Causes of Breast Cancer.

The reasons behind breast cancer often are hormonal changes within the body: the entry into menopause, should there be an energetic restructuring of the hormonal regulation from the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, our bodies will go through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most tuned in to these changes, the breast growth starts to dissolve and turn into replaced by fat.

Scientifically established that the female hormones estrogen-, plays an important role in the progression of cancer of the breast. The excess hormones in the body creates a favorable background for developing the condition. 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 cut back potential risk of developing breast cancers. On the other hand, abortion bring about hormonal "explosion" inside a woman's body that may trigger the progression of tumors. So far there is no consensus concerning the impact on the progression of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce potential risk of developing cancer of the breast, but increase the chance of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast could cause harmful environmental factors: environmental surroundings, along with inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a group of first-degree relatives with breast cancers (mothers and sisters) probability of having a tumor increasing by over half - familial varieties of cancer.

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't result in cancer, but simultaneously, create an unfavorable background due to the development.

The cause of breast cancers will be the results of radiation, including 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 lead to cancer from the breast and female reproductive system, having an excess fat within the body, it might be another endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are several forms with the growth of breast cancer:

- Nodular form, the most common, is seen as a dense knot of 0.5 to cm or more, it is seen as an all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" of the breast and skin. For the first 2 forms are characteristic signs of inflammation: pain with the breast, a bright red color in the skin it raises body temperature to 39 degrees C. In view of the symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that are named and are described these forms cancer of the breast. When tubular carcinoma breast cancers cover like a "skin" of its contracting and decreasing in proportions.

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

For small tumors with the breast, any symptoms arise. The most observant ladies and their husbands are able to detect tumor site inside the gland unintentionally, 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 favor of a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, can be firmly fixed towards the surrounding tissue or skin, usually painless, can reach an important size (more than 3 to 5 cm and infrequently 10-15 cm).

Need to assess the surface in the skin within the tumor: the malignant process will probably be observed retraction of the skin, obtaining inside folds, wrinkles, an indicator of "lemon peel" - an area swelling from the skin over the tumor, may be a direct tumor invasion to the skin surface, then it will become a bright beautiful red colors and sprawl as "cauliflower."
