Breast Cancer

Among all cancers in females, he takes consumers. In most cases, cancer of the breast develops inside 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 of the nipple and also the nipple in the field (Paget's disease from the breast). For the nodular cancers are seen as a the node creating a diameter up to several centimeters. In certain cases, a tight knot, is permeated with whitish layers tissue penetrating in to the surrounding fat, in others - a soft, juicy about the cut, splits easily. Diffuse prostate cancer is included to get a considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades your skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads along the surface with the breast and all the iron is roofed using a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers could be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is seen as varying levels of tissue and cell irregularities, which permitted to distinguish different amount of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which in turn has the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The reasons behind breast cancers often are hormonal changes inside body: the entry into menopause, should there be an energetic restructuring of the hormonal regulation from the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, one's body will go through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most tuned in to these changes, the breast type tissue actually starts to dissolve and be replaced by fat.

Scientifically established that this female hormones estrogen-, plays a vital role in the development of breast cancers. The excess hormones inside body generates a favorable background for developing the illness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (greater than 12 months) to relieve potential risk of developing breast cancer. On the other hand, abortion bring about hormonal "explosion" in a woman's body that can trigger the development of tumors. So far there's no consensus concerning the impact for the growth and development of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce the chance of developing cancer of the breast, but increase the potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast can cause harmful environmental factors: the planet, as well as 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 varieties of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to result in cancer, but at the same time, create an unfavorable background due to the development.

The reason for cancer of the breast would be the connection between radiation, like irradiation in 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 with the breast and female the reproductive system, by having an excess dimply skin within the body, it becomes a different endocrine organ and starts to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

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

- Nodular form, the most common, is seen as a a dense knot of 0.5 to 5 cm or maybe more, it can be characterized by all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" of the breast and skin. For the first couple of forms are characteristic signs and symptoms of inflammation: pain with the breast, a bright red color with the skin it raises 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 known as these forms breast cancers. When tubular carcinoma breast cancer cover being a "skin" of its contracting and decreasing in space.

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

For small tumors from the breast, any symptoms arise. The most observant ladies and their husbands are able to detect tumor site inside gland by accident, but in a very large breast to detect small size hard knot. Revealed a knot may be painful when pressed, round, smooth and agile, this speaks in support of a benign tumor. Signs of malignancy other: a strong knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, can be firmly fixed for the surrounding tissue or skin, usually painless, can reach a significant size (greater than 3 to 5 cm and sometimes 10-15 cm).

Need to evaluate the surface from the skin in the tumor: the malignant process will likely be observed retraction of the skin, obtaining in the folds, wrinkles, an indication of "lemon peel" - a neighborhood swelling from the skin within the tumor, may be a direct tumor invasion to skin surface, then it will become a bright red color and sprawl as "cauliflower."
