　　According to the British "Independent" report, American scientists have recently developed a new type of anti-cancer therapy, combining nanotechnology and anti-cancer drugs to successfully cure experimental mice suffering from breast cancer. Scientists said that the latest technology is expected to provide new methods for the treatment of lung and liver metastatic cancer. The research team led by Moro Ferrari, director of the Houston Methodist Hospital Research Institute, injected a porous silicon material that had absorbed the anti-cancer drug doxorubicin into mice suffering from breast cancer (the tumor has spread to the lungs). The material will be transported by the blood to the tumor site, where the silicon will decompose, producing nanoparticles that kill the cancer. The researchers explained that this "nanoparticle generator" can effectively concentrate anti-cancer drugs in tumor cells while ignoring healthy cells, thereby avoiding the toxic side effects of traditional chemotherapy methods.

　　Research has shown that after 8 months of tracking (equivalent to 24 years of humans), half of the diseased mice were cured. Ferrari said the results in mice were "unprecedented", and this is the first cured case of breast cancer that has metastasized to the lungs. In the experiment, standard chemotherapeutics were used, and the real "behind the scenes" is the drug delivery mechanism using nanotechnology. If this discovery can be repeated by other scientists, it will become a new milestone in the field of cancer treatment. Ferrari said: "Lung and liver metastases are the "two killers" that kill cancer patients. The latest research shows that we may be able to provide a functional therapy for them. We can cure 50% of diseased mice. They can Life is free of disease for a long time. In addition, a deep understanding of this mechanism allows us to find a way to treat another 50% of diseased mice. If this research is confirmed in humans, then we will completely change the metastatic disease The current status of treatment, metastatic disease is no longer a death sentence."
