Breast Cancer

Among all cancers in ladies, he takes the ultimate place. In most cases, breast cancers 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 of the nipple and the nipple from the field (Paget's disease with the breast). For the nodular cancers are seen as an the node creating a diameter of up to several centimeters. In some instances, a tight knot, is permeated with whitish layers tissue penetrating to the surrounding fat, in other people - a soft, juicy around the cut, splits easily. Diffuse cancer of prostate is roofed for a considerable distance, the contours in the tumor are marked bad. Sometimes the cancer invades your skin layer and forms on the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads down the surface in the breast and the iron is covered using a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is seen as varying degrees of tissue and cell irregularities, which allowed to distinguish different amount of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which usually has got the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The factors behind cancer of the breast often are hormonal changes inside the body: the entry into menopause, if you find a dynamic restructuring in the hormonal regulation in the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, our bodies goes through, "hormonal crisis." The mammary gland and endometrium (lining with the uterus) are most tuned in to these changes, the breast growth actually starts to dissolve and stay replaced by fat.

Scientifically established that this female hormones estrogen-, plays a key role inside development of cancer of the breast. The excess hormones inside the body creates a favorable background for developing the disease. The least active hormones estrogen behave while pregnant and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (over 1 year) to cut back the potential risk of developing cancer of the breast. On the other hand, abortion bring about hormonal "explosion" inside a woman's body that can trigger the progression of tumors. So far there is no consensus about the impact around the progression of tumors of hormonal contraceptive drugs, however it is thought that these drugs reduce the potential risk of developing breast cancer, but increase the risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: environmental surroundings, along with inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a category of first-degree relatives with breast cancers (mothers and sisters) probability of developing a tumor increasing by greater than half - familial kinds of cancer.

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

The reason for breast cancers could be the results of 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 in the breast and female reproductive :, with the excess dimply skin inside the body, it becomes a different endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are some forms in the growth of breast cancers:

- Nodular form, the most common, is seen as an a dense knot of 0.5 to five cm or more, it really is seen as all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" with the breast and skin. For the first two forms are characteristic indications of inflammation: pain from the breast, a bright red colorization of the skin it raises temperature to 39 degrees C. In view of the symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, which are named and are referred to these forms cancer of the breast. When tubular carcinoma cancer of the breast cover being a "skin" of the company's contracting and decreasing in space.

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

For small tumors in the breast, any symptoms arise. The most observant as well as their husbands can easily detect tumor site inside the gland by chance, 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 in favor of 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, might be firmly fixed on the surrounding tissue or skin, usually painless, can reach an important size (over three to five cm and infrequently 10-15 cm).

Need to gauge the surface from the skin within the tumor: the malignant process is going to be observed retraction of the skin, picking up in the folds, wrinkles, an indication of "lemon peel" - a nearby swelling of the skin within the tumor, can be a direct tumor invasion to your skin surface, then it might be a bright red color and sprawl as "cauliflower."
