Breast Cancer

Among all cancers in ladies, he takes consumers. In most cases, breast cancer 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, as well as cancer from the nipple and the nipple with the field (Paget's disease of the breast). For the nodular cancers are seen as a the node having a diameter as high as several centimeters. In certain instances, a tight knot, is permeated with whitish layers tissue penetrating in to the surrounding fat, in other people - a soft, juicy for the cut, splits easily. Diffuse cancer of the prostate is covered for the considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades your skin layer 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 many types of the iron is included using a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as varying degrees 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 usually gets the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes within the body: the entry into menopause, if you find an energetic restructuring in the hormonal regulation with the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, our bodies is going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most attentive to these changes, the breast tissue actually starts to dissolve and stay replaced by fat.

Scientifically established the female hormones estrogen-, plays an integral role inside growth and development of breast cancers. The excess hormones within the body produces a favorable background for developing the disease. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (a lot more than 1 year) to relieve the potential risk of developing breast cancer. On the other hand, abortion cause hormonal "explosion" in a very woman's body that can trigger the continuing development of tumors. So far there isn't any consensus in regards to the impact for the continuing development of tumors of hormonal contraceptive drugs, but it is considered that these drugs reduce the potential risk of developing cancer of the breast, but increase potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancer can cause harmful environmental factors: the planet, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a family of first-degree relatives with breast cancers (mothers and sisters) chance of creating a tumor increasing by more than half - familial varieties of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not result in cancer, but simultaneously, create an unfavorable background for the development.

The source of breast cancer would be the connection between 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 result in cancer from the breast and female reproductive :, having an excess dimply skin in the body, it will become a separate endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are many forms in the growth of breast cancers:

- Nodular form, the most frequent, is characterized by a dense knot of 0.5 to five cm or more, it can be seen as all from 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 first two forms are characteristic signs and symptoms of inflammation: pain of the breast, a bright red color of the skin it raises body temperature to 39 degrees C. In view of the symptoms often occur, and errors in carried out patients treated for inflammatory diseases, that happen to be named and are known these forms cancer of the breast. When tubular carcinoma breast cancers cover as a "skin" of the company's contracting and decreasing in proportions.

In certain instances, cancer of the breast manifests inside form of metastases inside the lymph nodes on the affected side, often doesn't detect the tumor itself - show hidden breast cancers.

For small tumors from the breast, any symptoms arise. The most observant women and their husbands can detect tumor site inside gland accidentally, 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 decent knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, could be firmly fixed to the surrounding tissue or skin, usually painless, can reach an important size (a lot more than 3 - 5 cm and quite often 10-15 cm).

Need to gauge the surface from the skin within the tumor: the malignant process will likely be observed retraction of the skin, collecting inside the folds, wrinkles, an indication of "lemon peel" - a neighborhood swelling in the skin in the tumor, is often a direct tumor invasion to your skin surface, then it becomes a bright red color and sprawl as "cauliflower."
