On average, every American has about 40% chance to develop cancer during his or her lifetime. Most cancer research institutes and pharmaceutical companies only focus on developing drugs that treat cancer after it has taken roots in people. Far too often, these treatments have severe and debilitating side effects with slim chances of working. Most people now would like to know how to prevent cancer before it hit us and our family.After 20-year experience in biomedical research, especially in tumor biology and anti-cancer drug discovery research, I learned the following questions are key to effectively prevent cancer:What cause cells in our body to become cancerous and how can we minimize our exposure to these cancer-causing agents?What are the physiological conditions that wake up dormant small tumors and support cancer growth, and how can we maintain our physiological condition that suppresses or truncates cancer growth?Q&Aid conducts scientific research for cancer prevention and reveals potential medicinal herbs as health promoting agent to balance our physiological conditions reducing cancer risk. We are committed to enable healthy life through science and nature resources.Cancer is a serious public health issue. We all need to develop a fundamental sense of a healthy lifestyle for cancer prevention. This includes:Eating diversified and healthy food,Exercising regularly, or conducting good amount physical activities,Having happy and positive mental settings.
