Breast cancer


Breast cancer is the most frequent procedure type of cancer that occurs in women. 
Calculated by a devastating fact that one woman dies every thirteen minutes in the world of breast cancer.
Early detection is often life saving. When breast cancer is detected early, the five-year survival rate is almost 97%.

What is breast cancer?

Breast cancer occurs when cancer cells lose their characteristic of healthy cells and start to divide uncontrollably.
The development of metastases and metastatic disease are talking like this when a malignant transformed cells leave the blood and breast
reach the lymph or other tissues and organs in which they keep and that they start to divide.


Risk Factors

Today, some of the known risk factors for developing breast cancer.
These are: age (the risk of developing cancer increases with age), mutations in certain genes (genes labeled BRCA1 and BRCA2), the early first menstruation (before age of twelve),
late menopause (after fifty years), late first pregnancy (women who were not born as a much higher risk of cancer),
positive family history (occurrence of cancer in first-degree relatives), radiation, obesity, alcohol, smoking.

Prevention of disease ie. Prevention of disease progression, and that it does not occur, is always the best solution.
This implies a reduction of risk factors that may be affected.
Diet should be balanced, that includes foods low in fat,
with plenty of fruits and vegetables that provide vitamin and antioxidant, which prereveniraju cancer development in general.
Reduced intake of animal fat in the daily diet of origin, is one way to prevent breast cancer.
Mono-unsaturated oils such as olive, are healthier than polyunsaturated oils (sunflower and kukurzno) and trans-fatty acids (margarine) and reduce the risk of cancer.
It is also important to reduce alcohol intake.
Women who entered day two or more alcoholic beverages, have 1.5 times higher risk of breast cancer. Physical activity reduces the risk of cancer.
It is highly recommended obese women. Smoking, as well as for most other diseases, increases the risk of developing cancer

Making a diagnosis

The diagnosis of breast cancer usually begins detecting changes in the standard breast examination or screening mammography.
Most of these lesions was fortunately benign.
However, to obtain a definitive diagnosis usually continues with a number of further analyzes that include mammography, ultrasound,
Fine needle aspiration and in some cases surgical confirmation, a biopsy.
Such a wide range of tests is often necessary because of the low specificity of current screening methods, especially in younger women.
This often exposes these women to great stress and anxiety during anticipation of results.
Time to perform all necessary tests and get results, takes a while.

How can you reduce the number of biopsy

In many countries of the world has become available to a non-invasive method for detecting breast cancer and thus is izbegnto waste of precious time and stress that these women face.
It all started in 1998th when the first study done with a new way of testing that would be followed in future years this method has developed, perfected and made public.
Non-invasive diagnostic technique based on measurements of electro potential on the skin surface and thus allows differentiation of benign disease of breast cancer. The test was developed by the U.S. Biofield Corp., Atlanta, Georgia. The device used is similar to a standard EKG machine.
In the first study published u'Lancet '661 women participated in eight major medical centers that have previously undergone biopsy because of suspicious breast lesions.
Dr Jack Cuzick showed that when the system operates with a sensitivity of 90% has a specificity of 55% which would mean that even more than half of the biopsy could be avoided.
The test is noninvasive and is based on changes in the distribution of electrical potential that is different in breast cancer compared to healthy tissue. This allows physicians more easily assess whether a change is benign or malignant. All this with other clinical results can assist in making further decisions and the potential need for biopsy.
Thus reducing the loss of precious time, which in our country there is often reduces the cost of inspection, anxiety and stress that these women face. This approach could avoid the costly and often unnecessary analysis and to save money.
This method represents a different approach in the diagnosis of cancer. It could complement the new screening methods in the diagnosis of cancer. Some of the advantages of this method are as painless and available to the general population, with results after only ten to fifteen minutes. Also, it could indicate the level of activity, ie the proliferation of tumor cells, with a high security can be applied in younger women with contra X-rays.
