Breast Cancer

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

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

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancer might 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 able to distinguish different amount of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which will has got the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The factors behind cancer of the breast often are hormonal changes in the body: the entry into menopause, when there is an active restructuring from the hormonal regulation with 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 of the uterus) are most responsive to these changes, the breast growth starts to dissolve and be replaced by fat.

Scientifically established that this female hormones estrogen-, plays an important role within the continuing development of breast cancers. The excess hormones inside the body produces a favorable background for developing the sickness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (more than twelve months) to relieve the potential risk of developing breast cancers. On the other hand, abortion result in hormonal "explosion" in the woman's body that can trigger the continuing development of tumors. So far there's no consensus in regards to the impact on the development of tumors of hormonal contraceptive drugs, yet it's thought that these drugs reduce the potential risk of developing breast cancers, but increase the potential risk of developing cancer from the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast can cause harmful environmental factors: environmental surroundings, along with inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a group of first-degree relatives with breast cancer (mothers and sisters) likelihood of creating a tumor increasing by over half - familial kinds of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't lead to cancer, but concurrently, create an unfavorable background for the development.

The reason behind cancer of the breast would be the outcomes of radiation, like irradiation with 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 of the breast and female the reproductive system, with the excess fatty tissue inside the body, it might be an outside endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are some forms in the growth of breast cancers:

- Nodular form, the most frequent, is seen as a a dense knot of 0.5 to 5 cm or even more, it really 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" in the breast and skin. For the first two forms are characteristic signs and symptoms of inflammation: pain in the breast, a bright red color of the skin it raises body's temperature to 39 degrees C. In view of the symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, which can be named and therefore are known these forms breast cancers. When tubular carcinoma breast cancer cover as being a "skin" of the company's contracting and decreasing in size.

In some cases, breast cancers manifests within the form of metastases in the lymph nodes about the affected side, often doesn't detect the tumor itself - show hidden cancer of the breast.

For small tumors with the breast, any symptoms arise. The most observant females and their husbands can easily detect tumor site inside gland accidentally, but in a large breast to detect small size hard knot. Revealed a knot may 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 is stationary or slightly shifted, may be firmly fixed to the surrounding tissue or skin, usually painless, can reach a tremendous size (a lot more than 3 to 5 cm and quite often 10-15 cm).

Need to evaluate the surface with the skin over the tumor: the malignant process will probably be observed retraction from the skin, buying inside folds, wrinkles, an indicator of "lemon peel" - a neighborhood swelling from the skin in the tumor, is often a direct tumor invasion to skin surface, then it might be a bright beautiful red colors and sprawl as "cauliflower."
