Breast Cancer

Among all cancers in females, he takes the ultimate place. In most cases, breast cancers 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 in 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 having a diameter of up to several centimeters. In certain cases, a strong knot, is permeated with whitish layers tissue penetrating in the surrounding fatty tissue, on other occasions - a soft, juicy about the cut, splits easily. Diffuse cancer of prostate is included to get a considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades skin and forms for the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads across the surface in the breast and all the iron is covered 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 a varying examples of tissue and cell irregularities, which in a position to distinguish different level of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which will gets 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, should there be an energetic restructuring with the hormonal regulation in the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, one's body goes through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most responsive to these changes, the breast tissue starts to dissolve and stay replaced by fat.

Scientifically established that the female hormones estrogen-, plays an important role inside the growth and development of breast cancers. The excess hormones within the body creates a favorable background for developing the disease. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (over 1 year) to reduce the chance of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" in a very woman's body that can trigger the development of tumors. So far there is no consensus concerning the impact about the continuing development 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 of the female genital organs, and osteoporosis. In addition predisposition to breast cancer may cause harmful environmental factors: the environment, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a category 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 like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to lead to cancer, but as well, create an unfavorable background because of its development.

The cause of breast cancers will be the connection between radiation, like irradiation of 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 in the breast and female reproductive :, by having an excess dimply skin in the body, it might be a different 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 in the growth of cancer of the breast:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" of the breast and skin. For the initial two forms are characteristic signs of inflammation: pain of the breast, a bright red colorization in the skin it raises body's temperature to 39 degrees C. In view of such symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, which can be named and so are known these forms breast cancer. When tubular carcinoma cancer of the breast cover being a "skin" of the contracting and decreasing in size.

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

For small tumors of the breast, any symptoms arise. The most observant women and their husbands have the ability to detect tumor site in the gland unintentionally, but in a 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 tight knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, may be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a significant size (more than 3 to 5 cm and infrequently 10-15 cm).

Need to evaluate the surface from the skin on the tumor: the malignant process will likely be observed retraction of the skin, obtaining inside folds, wrinkles, a signal of "lemon peel" - an area swelling from the skin in the tumor, might be a direct tumor invasion to the skin surface, then it might be a bright red colorization and sprawl as "cauliflower."
