In recent decades, research the use of nanotechnologies in the diagnosis and therapy of cancer continue to be developed. With this technology, gene inhibitor of cancer cells in liposomal nanoparticles inserted directly into the human blood circulation system.
It is intended that the cancer cells and tumors in all shapes and sizes can be directly destroyed. This was stated by Esther H. Chang of the Lombardi Comprehensive Cancer Center Georgetown University Medical Center, United States, on Saturday (10 / 5) at the Universitas Pelita Harapan (UPH), Tangerang.
Esther stated, the use of nano technology could improve the therapeutic effectiveness and minimize side effects because it only destroys the body's tissues affected by cancer and does not damage healthy tissue. So far clinical trials the use of nano particles in cancer therapy have been made to examine the appropriate dose.
Director of International Relations of the National Cancer Institute of the United States Joe B Harford added, the potential of nanotechnologies in medicine in general is realized. So far the use of nanotechnologies to the general treatment is still limited, but much research has been done. The development of this research is needed to determine the level of safety and efficacy of cancer treatment with nanotechnologies.

These nano technologies need to be developed because, "In some patients, the cancer cells resistant to radiation and chemotherapy," said Esther.
Cancer patients usually undergo standard treatment, namely radiation therapy and chemotherapy. Chemotherapy drugs attack not only cancer cells but also healthy cells which then grow rapidly.
Currently, many countries around the world are developing this technology, including the United States, Japan, Korea, and several countries in Europe. National Nanotechnology Initiative United States, established in 2000, this year allocated a budget of more than 1 billion U.S. dollars. "Some drugs with nano technology is being tested clinic, and there are already marketed," he said.
Resistance of cancer cells
Meanwhile, also discussed the situation now, as environmental and lifestyle changes, the situation of epidemic diseases in the world increasingly worried about cancer.
This is compounded by the increasing resistance of cancer cells to radiation therapy and chemotherapy. Nanotechnologies for cancer therapies developed to overcome the problem.
According to the Harford in his paper at the symposium "Frontier of Cancer Research", Sunday, at the FMU, the number of deaths from cancer outnumber deaths from AIDS, tuberculosis, and malaria. Population problems and lifestyle changes improve cancer disease, especially in middle income countries down.
By 2030, about 70 percent of cancer deaths occur in developing countries due to lack of capacity and access to health care systems.
Head of the Laboratory of Human Carcinogenesis National Cancer Institute of the United States Curtis Harris added that the control of cancer risk factors need to be done as a precaution with early detection. A number of risk factors that need to be aware of other genetic or hereditary, environmental, and lifestyle. "Do not eat one food in excess," he said.
According to the study of lifestyle factors and cancer in Shanghai, China, Yong Bing Xiang, are discussed from the Department of Epidemiology Cancer Institute of Shanghai, China, smoking habits associated with death from cancer in the lungs, stomach, and pancreas.
Consumption of tea might prevent cancer development. In women, exposure to cigarette smoke (passive smoking) in the workplace and the family increases the risk of cancer and cardiovascular disease.
