Breast Cancer

Among all cancers in ladies, 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, in addition to cancer in the nipple along with the nipple in the field (Paget's disease in the breast). For the nodular cancers are seen as an the node developing a diameter as high as several centimeters. In some cases, a tight knot, is permeated with whitish layers tissue penetrating in the surrounding fatty tissue, in other people - a soft, juicy on the cut, splits easily. Diffuse cancer of the prostate is included for a considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades the skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads across the surface from the breast and many types of the iron is included with a dense shell.

In histological structure would be the following varieties of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as a varying levels of tissue and cell irregularities, which in a position to distinguish different degree of malignancy. This type of cancer include, in particular, infiltrating ductal and lobular carcinoma, which in turn gets the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes in the body: the entry into menopause, if you find an energetic restructuring with the hormonal regulation with the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, your body will go through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most understanding of these changes, the breast tissue begins to dissolve and be replaced by fat.

Scientifically established how the female hormones estrogen-, plays a vital role inside continuing development of breast cancer. The excess hormones in the body creates a favorable background for developing the disease. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved the birth and prolonged breastfeeding (over 12 months) to reduce the chance of developing cancer of the breast. On the other hand, abortion lead to hormonal "explosion" in the woman's body that can trigger the growth and development of tumors. So far there's no consensus in regards to the impact for the development of tumors of hormonal contraceptive drugs, but it's considered that these drugs reduce the risk of developing breast cancers, but increase the chance of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: the surroundings, along with inflammatory diseases previously deferred breast - mastitis.

In addition, patients having a group of first-degree relatives with cancer of the breast (mothers and sisters) chance of having a tumor increasing by a lot more than half - familial types of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't result in cancer, but concurrently, create an unfavorable background due to the development.

The cause of breast cancer could be the effects of radiation, such as 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 lead to cancer with the breast and female reproductive system, with the excess fat inside the body, it becomes a separate endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are several forms from the growth of breast cancer:

- Nodular form, the commonest, is seen as a a dense knot of 0.5 to 5 cm or even more, it really is characterized by all from the following symptoms;

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

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

For small tumors of the breast, any symptoms arise. The most observant as well as their husbands have the ability to detect tumor site in the gland by accident, but in the large breast to detect small size hard knot. Revealed a knot can be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, can be firmly fixed to the surrounding tissue or skin, usually painless, can reach a substantial size (greater than 3 to 5 cm and infrequently 10-15 cm).

Need to gauge the surface with the skin within the tumor: the malignant process is going to be observed retraction with the skin, collecting inside the folds, wrinkles, a symptom of "lemon peel" - an area swelling with the skin within the tumor, may be a direct tumor invasion to your skin surface, then it will become a bright red colorization and sprawl as "cauliflower."
