Breast Cancer

Among all cancers in females, he takes the initial 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, and also cancer with the nipple and the nipple from the field (Paget's disease with the breast). For the nodular cancers are seen as a the node using a diameter of up to several centimeters. In some cases, a decent knot, is permeated with whitish layers tissue penetrating into the surrounding fatty tissue, in others - a soft, juicy around the cut, splits easily. Diffuse prostate cancer is included for a considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades your skin layer and forms around the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads over the surface in the breast and many types of the iron is roofed using a dense shell.

In histological structure would be the following types of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

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

Causes of Breast Cancer.

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

Scientifically established that this female hormones estrogen-, plays a key role within the progression of breast cancer. The excess hormones inside the body results in a favorable background for developing the sickness. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (greater than one year) to reduce the potential risk 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 in regards to the impact on the progression of tumors of hormonal contraceptive drugs, yet it's considered that these drugs reduce potential risk of developing cancer of the breast, but increase the potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancer could cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a group of first-degree relatives with cancer of the breast (mothers and sisters) risk of making a tumor increasing by over half - familial forms of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not cause cancer, but at the same time, create an unfavorable background for the development.

The cause of breast cancers will be the outcomes 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 the reproductive system, with 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 some forms from the growth of breast cancers:

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

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" with the breast and skin. For the first couple of forms are characteristic signs of inflammation: pain with the breast, a bright red color from the skin it raises temperature to 39 degrees C. In view of such symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, which are named and they are described these forms breast cancers. When tubular carcinoma cancer of the breast cover as being a "skin" of the company's contracting and decreasing in proportions.

In some instances, breast cancer manifests inside form of metastases inside lymph nodes on the affected side, often does not detect the tumor itself - show hidden breast cancer.

For small tumors of the breast, any symptoms arise. The most observant females and their husbands have the ability to detect tumor site inside gland by chance, but in a very large breast to detect small size hard knot. Revealed a knot might 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, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach an important size (over 3 - 5 cm and sometimes 10-15 cm).

Need to evaluate the surface with the skin within the tumor: the malignant process will likely be observed retraction from the skin, obtaining in the folds, wrinkles, an indication of "lemon peel" - a nearby swelling of the skin in the tumor, may be a direct tumor invasion to skin surface, then it might be a bright beautiful red colors and sprawl as "cauliflower."
