we celebrate the World Day Against Breast Cancer and from the Health Channel jurnalk3.com we take to try to raise, once again, the people of the importance of prevention in these diseases, also to congratulate all those women that recently suffered a tumor of this type and have successfully passed and, of course, give our wholehearted support for those currently struggling to overcome it.

Breast cancer is one of the tumors with the highest incidence among the population and one of the leading causes of death in women in Spain alone there are more than 20,000 new cases every year according to the Spanish Association against Cancer (AECC). However, thanks to advances in treatment, both the survival rate and quality of life of the patient improved considerably, always remembering the importance of early diagnosis. Therefore, it is important to go to regular gynecological examinations, mammograms regularly and observe any changes in the body through breast self-exam at least once a month, especially if a family history.

In the British Medical Journal published research that revealed that passive smoking increases the risk of breast cancer. An analysis of data from nearly 80,000 women shows that exposure to snuff smoke at work or at home for many years increases the chances of developing this tumor.

According to Argentina’s medical issue, researchers at West Virginia University, USA, say that women who do not smoke but are exposed to smoke from other people snuff are more likely to develop breast cancer, as published by the British Medical Journal.

Apparently, the investigation involved nearly 80,000 women and, according to its authors, the incidence of these tumors was 32% higher in those who had decades as passive smokers, a finding that should be confirmed with further studies.

The relationship between passive smoking and breast cancer has always been a controversial issue because, while some studies found a relationship like this, there were others who refused as it was difficult to quantify the minimum time of exposure carries a risk.
In this study, women participants were between 50 and 79 years and, during the 10-year follow-up during the investigation, we detected 3250 cases of invasive breast cancer.

When women were asked about their smoking history and exposure to tobacco snuff, it was found that smokers had a 16% increased risk of developing breast cancer after menopause. For former smokers, the risk was 9% and remained for 20 years after quitting, being highest in those who had smoked for over 50 years.

What is surprising, as highlighted by the study authors, is that women who had never smoked but lived with smokers or had worked for several years seemed to have also an increased risk of breast cancer.

Thus, “after more than 10 years of exposure to snuff in childhood or as adults, after more than 10 years of passive smoking at work or at home 20, the risk increased by 32%.”

According to Dr. Rachel Greig, from Breakthrough Breast Cancer, the study suggests that “soon begin to smoke and takes longer to do so, the greater your chance of developing breast cancer.”

“We know that smoking has many health risks and is a major cause of lung cancer and heart disease, and encourage all women who do not smoke,” he concluded.

A publication IRIN, research reveals that claims to find potential benefits of marijuana in relation to the reduction of tumors. According to this publication, a team of scientists from the Autonomous University of Madrid (UAM), Universidad Complutense (UCM) and the National Center for Biotechnology (CNB) has found that the active components of marijuana and its derivatives exert a “potent” antitumor in a genetic model of breast cancer by reducing the number and size of tumors and lung metastases.

The research, published in ‘Molecular Cancer’, established that cannabinoids exert a marked antitumor effect in the genetic model of breast cancer ‘MMTVneu’, as it not only dramatically reduce tumor growth and metastasis, but are also able to block the own generation of new tumors.

Specifically, mice ‘MMTVneu’ spontaneously generated breast tumors that metastasize to the lung later, because they express high levels of oncogene ‘ErbB2′. This protein is also overexpressed in 25 to 30 percent of human breast tumors, which correlates with a more aggressive phenotype, a higher rate of recurrence or metastases and therefore with a worse prognosis, say the researchers.

For these reasons, they say, the mice used in this study are a good model for this kind of breast tumors, known as ‘HER2′ positive, for which new therapies are needed. The researchers have also shown that cannabis stop growth and induce death of cultured cells derived from human breast tumors ‘ErbB2′ positive.

In both cases (in the animal model ‘MMTVneu’ and in human tumor cells) the antitumor effect of these compounds appears to be mediated by the cannabinoid receptor ‘CB2′. The psychotropic effects associated with cannabis use are mainly due to receptor activation ‘CB1′, which is predominantly expressed in the nervous system.

Therefore, the Spanish scientists say, an antitumor therapy based on drugs that selectively activate the receiver ‘CB2′ “not trigger the psychotropic effects normally associated with marijuana use.”

Another aspect that would add security to this therapy is that cannabinoids act selectively on breast tumor cells without affecting cells in normal breast epithelium (no tumor), as shown by the same research group in a previous article published in the journal Cancer Research.

In conclusion, the researchers propose that cannabinoids, especially compounds that selectively activate the receiver ‘CB2′ may be used alone or in combination with other antitumor drugs for the treatment of this type of breast tumors that are needed for more effective therapies.

Breast cancer is a disease of greatest concern to society, especially women. It is a condition in which specialists are putting all their efforts and results of different studies are very promising for the future.

The risk of a woman having breast cancer grows as the years pass, and for this reason doctors recommend that from the age of 40 diagnostic studies are performed.

It is true that today is becoming increasingly sophisticated diagnostic techniques and treatment for this disease, but be aware that if people are not aware of the importance of periodic inspections cannot stop in time this disease.

One of the less negative breast cancers is treatable, and there are women who have passed twice. The process is not easy, but you just have to have some hope.
