Breast Cancer

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

MRI tumor features help predict breast cancer recurrence

In histological structure are the following types of cancer of the breast:

• 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 seen as varying examples of tissue and cell irregularities, which able to distinguish different degree of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which usually contains the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

The factors behind breast cancer often are hormonal changes inside body: the entry into menopause, should there be an active restructuring of the hormonal regulation with the woman, the ovaries lose their activity, decreased creation of progesterone and estrogen, our bodies will go through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most understanding of these changes, the breast tissue actually starts to dissolve and turn into replaced by fat.

Scientifically established how the female hormones estrogen-, plays a vital role in the growth and development of breast cancers. The excess hormones inside body results in a favorable background for developing the disease. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (greater than 1 year) to lessen potential risk of developing breast cancers. On the other hand, abortion result in hormonal "explosion" in a woman's body that will trigger the growth and development of tumors. So far there is absolutely no consensus regarding the impact on the progression of tumors of hormonal contraceptive drugs, but it is considered that these drugs reduce the potential risk 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 might cause harmful environmental factors: the surroundings, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a group of first-degree relatives with cancer of the breast (mothers and sisters) probability of making 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 do not lead to cancer, but concurrently, create an unfavorable background because of its development.

The cause of breast cancer may be the results of radiation, like irradiation with 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 :, with the excess fatty tissue within the body, it is an outside 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 from the growth of breast cancers:

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

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

MRI Shows Potential to Improve Breast Cancer Risk Prediction

In certain cases, breast cancers manifests within the form of metastases inside lymph nodes on the affected side, often does not 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 can detect tumor site inside gland accidentally, 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 support of a benign tumor. Signs of malignancy other: a tight knot to touch the stone, its surface is uneven, it can be stationary or slightly shifted, could be firmly fixed towards the surrounding tissue or skin, usually painless, can reach a significant size (a lot more than three to five cm and infrequently 10-15 cm).

Need to gauge the surface of the skin on the tumor: the malignant process will likely be observed retraction in the skin, picking up inside folds, wrinkles, a symptom of "lemon peel" - a neighborhood swelling in the skin over the tumor, is often a direct tumor invasion to your skin layer surface, then it will become a bright red color and sprawl as "cauliflower."
