Breast cancer is the most prevalent of the different neoplasms that form part of what is known as "gynecological cancer" and is the leading cause of death in women between the ages of 20 and 60. This means that thousands, even millions, of people suffer from the symptoms associated with this type of cancer, so research into a non-pharmacological way of alleviating the symptoms could be the answer to the pain, anxiety, stress and depression suffered by many people diagnosed with breast cancer.
