breast cancer on ultrasound looks like The Best Breast Cancer Ever: Time to Look Back and Laugh
Breast Cancer

Among all cancers in women, he takes consumers. In most cases, breast cancer 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, as well as cancer of the nipple and also the nipple from the field (Paget's disease with the breast). For the nodular cancers are seen as a the node creating a diameter of up to several centimeters. In certain instances, a good knot, is permeated with whitish layers tissue penetrating into the surrounding fatty tissue, in other people - a soft, juicy for the cut, splits easily. Diffuse cancer of prostate is included for any considerable distance, the contours in 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 in the breast and the iron is covered having a dense shell.

Common Breast Cancer Types and Ultrasound Images Interpretation New Health Advisor

In histological structure include the following varieties of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive cancer of the breast could 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, particularly, infiltrating ductal and lobular carcinoma, which usually has the structure of scirrhus, in addition to Paget's disease.

Causes of Breast Cancer.

The reasons behind cancer of the breast often are hormonal changes within the body: the entry into menopause, should there be an energetic restructuring from 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 responsive to these changes, the breast tissue starts to dissolve and turn into replaced by fat.

Scientifically established that the female hormones estrogen-, plays an important role inside growth and development of breast cancers. The excess hormones within the body results in a favorable background for developing the illness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (over 1 year) to cut back the risk of developing breast cancer. On the other hand, abortion lead to hormonal "explosion" in the woman's body that could trigger the growth and development of tumors. So far there is absolutely no consensus regarding the impact on the continuing development of tumors of hormonal contraceptive drugs, but it is considered that these drugs reduce the potential risk of developing breast cancer, but increase the potential risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to breast cancers could 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 greater than half - familial kinds of cancer.

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

The reason behind breast cancers could be the outcomes 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 cause cancer from the breast and female reproductive :, by having an excess fat inside body, it will become a different endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the progression of tumors.

Symptoms of Breast Cancer

There are several forms from the growth of breast cancers:

- Nodular form, the most typical, is seen as a dense knot of 0.5 to five cm or maybe more, it can be seen as an all with the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" of the breast and skin. For the first 2 forms are characteristic indications of inflammation: pain of the breast, a bright red color in the skin it raises body's temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosing patients treated for inflammatory diseases, that happen to be named and therefore are known these forms breast cancer. When tubular carcinoma breast cancer cover as a "skin" of the company's contracting and decreasing in space.

In certain instances, breast cancers manifests within the form of metastases within the lymph nodes about the affected side, often ceases to detect the tumor itself - show hidden cancer of the breast.

For small tumors from the breast, any symptoms arise. The most observant as well as their husbands can easily detect tumor site inside gland unintentionally, 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 and only a benign tumor. Signs of malignancy other: a tight knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, may be firmly fixed for the surrounding tissue or skin, usually painless, can reach a tremendous size (more than 3 to 5 cm and quite often 10-15 cm).

Need to assess the surface in the skin on the tumor: the malignant process will probably be observed retraction of the skin, obtaining inside the folds, wrinkles, an indication of "lemon peel" - a nearby swelling with the skin on the tumor, may be a direct tumor invasion to your skin layer surface, then it might be a bright red colorization and sprawl as "cauliflower."
