Breast Cancer

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

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying examples of tissue and cell irregularities, which allowed to distinguish different a higher level malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which usually has the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancers often are hormonal changes inside the body: the entry into menopause, if you have a dynamic restructuring from the hormonal regulation of the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, one's body is going through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most tuned in to these changes, the breast growth starts to dissolve and be replaced by fat.

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

In addition, patients using a family of first-degree relatives with cancer of the breast (mothers and sisters) chance of having a tumor increasing by over half - familial kinds of cancer.

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

The reason behind breast cancers could be the outcomes of radiation, like 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 reproductive system, by having an excess fatty tissue in the body, it is a separate endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are several forms with the growth of cancer of the breast:

- Nodular form, the most frequent, is seen as a dense knot of 0.5 to five cm or even more, it's seen as an all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" from the breast and skin. For the first couple of forms are characteristic signs of inflammation: pain in 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 carried out patients treated for inflammatory diseases, which can be named and so are known as these forms breast cancer. When tubular carcinoma cancer of the breast cover being a "skin" of the contracting and decreasing in space.

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

For small tumors with the breast, any symptoms arise. The most observant women and their husbands can easily detect tumor site within the gland accidentally, but in the large breast to detect small size hard knot. Revealed a knot could be painful when pressed, round, smooth and agile, this speaks for a benign tumor. Signs of malignancy other: a strong knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, can be firmly fixed for the surrounding tissue or skin, usually painless, can reach a tremendous size (over three to five cm and quite often 10-15 cm).

Need to evaluate the surface in the skin in the tumor: the malignant process is going to be observed retraction with the skin, buying inside folds, wrinkles, an indicator of "lemon peel" - a nearby swelling in the skin in the tumor, may be a direct tumor invasion to the skin surface, then it will become a bright red colorization and sprawl as "cauliflower."
