Breast Cancer

Among all cancers ladies, he takes the initial place. In most cases, cancer of the breast 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, as well as cancer from the nipple and the nipple with the field (Paget's disease of the breast). For the nodular cancers are characterized by the node using a diameter as high as several centimeters. In some instances, a good knot, is permeated with whitish layers tissue penetrating to the surrounding dimply skin, on other occasions - a soft, juicy for the cut, splits easily. Diffuse prostate type of cancer is covered to get a considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades the skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads over the surface with the breast and all the iron is roofed using a dense shell.

In histological structure will 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 a varying degrees of tissue and cell irregularities, which able to distinguish different a higher level malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which often contains the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes within the body: the entry into menopause, when there is a dynamic restructuring of the hormonal regulation in the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, the body is going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most tuned in to these changes, the breast tissue actually starts to dissolve and stay replaced by fat.

Scientifically established the female hormones estrogen-, plays an important role inside development of cancer of the breast. The excess hormones in the body creates a favorable background for developing the disease. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved that this birth and prolonged breastfeeding (a lot more than twelve months) to relieve potential risk of developing breast cancer. On the other hand, abortion bring about hormonal "explosion" in the woman's body that could trigger the growth and development of tumors. So far there is absolutely no consensus in regards to the impact on the progression of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce potential risk of developing breast cancer, 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: environmental surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a category of first-degree relatives with cancer of the breast (mothers and sisters) chance of developing a tumor increasing by over half - familial types of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not lead to cancer, but as well, create an unfavorable background for the development.

The reason behind breast cancers will be the connection between radiation, for example 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 result in cancer of the breast and female the reproductive system, with the excess fatty tissue in the body, it might be 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 many forms in 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 characterized by all in 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 2 forms are characteristic warning signs of inflammation: pain in the breast, a bright red color with the skin it raises body temperature to 39 degrees C. In view of these symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, that are named and are known these forms breast cancer. When tubular carcinoma breast cancers cover like a "skin" of its contracting and decreasing in proportions.

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

For small tumors of the breast, any symptoms arise. The most observant ladies and their husbands can easily detect tumor site inside gland accidentally, but inside a 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 tight knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, may be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a substantial size (greater than three to five cm and infrequently 10-15 cm).

Need to assess the surface with the skin within the tumor: the malignant process is going to be observed retraction of the skin, buying within the folds, wrinkles, a symptom of "lemon peel" - an area swelling of the skin on the tumor, may be a direct tumor invasion to your skin layer surface, then it is a bright red color and sprawl as "cauliflower."
