Breast Cancer

Among all cancers ladies, he takes the ultimate place. In most cases, breast cancers develops inside 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 of the nipple along with the nipple with the field (Paget's disease with the breast). For the nodular cancers are characterized by the node creating a diameter up to several centimeters. In certain cases, a strong knot, is permeated with whitish layers tissue penetrating in the surrounding fatty tissue, on other occasions - a soft, juicy on the cut, splits easily. Diffuse prostate type of cancer is included for the considerable distance, the contours with the tumor are marked bad. Sometimes the cancer invades your skin layer and forms about the surface of decaying mushroom formation - a cancerous ulcer. In certain cases, the tumor spreads across the surface with the breast and many types of the iron is covered using a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying degrees of tissue and cell irregularities, which allowed to distinguish different a higher level malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which will contains the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancer often are hormonal changes inside body: the entry into menopause, if you have an energetic restructuring with the hormonal regulation in the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, the body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most tuned in to these changes, the breast type tissue actually starts to dissolve and become replaced by fat.

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

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

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't result in cancer, but at the same time, create an unfavorable background because of its development.

The reason behind breast cancer will be the results of radiation, including 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 cause cancer in the breast and female reproductive system, with the excess fatty tissue in the body, it might be an outside endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are many forms in the growth of breast cancers:

- Nodular form, the most frequent, is seen as an a dense knot of 0.5 to cm or higher, it is seen as all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" with the breast and skin. For the first two forms are characteristic warning signs of inflammation: pain with the breast, a bright red colorization from the skin it raises body's temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, which are named and are known these forms cancer of the breast. When tubular carcinoma breast cancers cover as a "skin" of the contracting and decreasing in space.

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

For small tumors in the breast, any symptoms arise. The most observant females and their husbands can detect tumor site in the gland unintentionally, but in a large breast to detect small size hard knot. Revealed a knot can be painful when pressed, round, smooth and agile, this speaks in favor 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, might be firmly fixed to the surrounding tissue or skin, usually painless, can reach a tremendous size (over 3 to 5 cm and quite often 10-15 cm).

Need to evaluate the surface with the skin in the tumor: the malignant process will likely be observed retraction from the skin, picking up within the folds, wrinkles, a symptom of "lemon peel" - a nearby swelling from the skin within the tumor, may be a direct tumor invasion to your skin layer surface, then it becomes a bright red colorization and sprawl as "cauliflower."
