Breast Cancer

Among all cancers in ladies, he takes consumers. In most cases, cancer of the breast 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, in addition to cancer from the nipple and the nipple of the field (Paget's disease of the breast). For the nodular cancers are seen as a the node creating a diameter all the way to several centimeters. In some instances, a good knot, is permeated with whitish layers tissue penetrating in to the surrounding fat, on other occasions - a soft, juicy for the cut, splits easily. Diffuse prostate type of cancer is covered to get a 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 some instances, the tumor spreads over the surface from the breast and all sorts of the iron is roofed with a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying levels of tissue and cell irregularities, which in a position to distinguish different degree of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which will contains the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancer often are hormonal changes inside body: the entry into menopause, if you have an energetic restructuring of the hormonal regulation of the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, our bodies is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most understanding of these changes, the breast type tissue starts to dissolve and stay replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role inside the development of breast cancers. The excess hormones in the body produces a favorable background for developing the condition. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (greater than 1 year) to cut back potential risk of developing breast cancer. On the other hand, abortion bring about hormonal "explosion" inside a woman's body that can trigger the continuing development of tumors. So far there is no consensus regarding the impact about the growth and development of tumors of hormonal contraceptive drugs, yet it's belief that these drugs reduce the risk of developing cancer of the breast, but increase the chance of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancers might cause harmful environmental factors: the environment, and also inflammatory diseases previously deferred breast - mastitis.

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

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

The cause of cancer of the breast may be the effects 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 cause cancer of the breast and female reproductive :, with the excess dimply skin inside the body, it might be an outside 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 some forms from the growth of cancer of the breast:

- Nodular form, the most common, is characterized by a dense knot of 0.5 to 5 cm or maybe more, it can be seen as all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" from the breast and skin. For the first two forms are characteristic indications of inflammation: pain with the breast, a bright red colorization of the skin it raises temperature to 39 degrees C. In view of those symptoms often occur, and errors in carried out patients treated for inflammatory diseases, which are named and so are known as these forms cancer of the breast. When tubular carcinoma breast cancers cover being a "skin" of their contracting and decreasing in size.

In some cases, breast cancer manifests inside form of metastases within the lymph nodes for 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 can detect tumor site within the gland accidentally, 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 and only a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, can be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (over 3 - 5 cm and sometimes 10-15 cm).

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