Breast Cancer

Among all cancers in women, he takes the first place. In most cases, breast cancer 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, along with cancer in the nipple and also the nipple of the field (Paget's disease from the breast). For the nodular cancers are seen as an the node having a diameter up to several centimeters. In some instances, a decent knot, is permeated with whitish layers tissue penetrating in to the surrounding dimply skin, in others - a soft, juicy for the cut, splits easily. Diffuse cancer of prostate is covered for any considerable distance, the contours from 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 some instances, the tumor spreads over the surface of the breast and all the iron is covered having a dense shell.

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

• noninvasive: intralobular and intraduct;

• infiltrative.

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

Infiltrating (invasive) cancer is characterized by varying examples of tissue and cell irregularities, which allowed to distinguish different amount of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which often has the structure of scirrhus, along with Paget's disease.

Causes of Breast Cancer.

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

Scientifically established the female hormones estrogen-, plays an integral role inside continuing development of breast cancer. The excess hormones within the body creates 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 (more than 1 year) to cut back the risk of developing cancer of the breast. On the other hand, abortion result in hormonal "explosion" in a woman's body that can trigger the progression of tumors. So far there's no consensus in regards to the impact for the progression of tumors of hormonal contraceptive drugs, however it is considered that these drugs reduce potential risk of developing breast cancers, but increase the potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to breast cancers can cause harmful environmental factors: the planet, along with inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a category 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 kinds of cancer.

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone don't result in cancer, but as well, create an unfavorable background because of its development.

The reason behind cancer of the breast would be the connection between radiation, including 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 result in cancer in the breast and female the reproductive system, with an excess fat within the body, it becomes another endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the development of tumors.

Symptoms of Breast Cancer

There are some forms in the growth of breast cancer:

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

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

In some instances, cancer of the breast manifests inside the form of metastases in the lymph nodes for the affected side, often does not detect the tumor itself - show hidden breast cancer.

For small tumors with the breast, any symptoms arise. The most observant ladies and their husbands can easily detect tumor site inside gland by accident, but inside a large breast to detect small size hard knot. Revealed a knot may 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's stationary or slightly shifted, may be firmly fixed on the surrounding tissue or skin, usually painless, can reach a significant size (over 3 to 5 cm and infrequently 10-15 cm).

Need to assess the surface with the skin in the tumor: the malignant process will likely be observed retraction from the skin, buying inside the folds, wrinkles, an indicator of "lemon peel" - a local swelling of the skin on the tumor, may be a direct tumor invasion to your skin layer surface, then it will become a bright red color and sprawl as "cauliflower."
