Ablation or Embolization Treatments for Pancreatic Cancer
Feb 11, 2019· Ablation and embolization treatments are different ways of destroying tumors, rather than removing them with surgery. They are used much less often for pancreatic cancers but can sometimes be used to help treat pancreatic cancer that has spread to other organs, especially the liver. These treatments ......

Ablation for Liver Cancer American Cancer Society
Apr 01, 2019· Ablation is treatment that destroys liver tumors without removing them. These techniques can be used in patients with a few small tumors and when surgery is not a good option (often because of poor health or reduced liver function). They are less likely to cure the cancer than surgery, but they can ......
Gold Nanolenses Generated by Laser AblationEfficient ...
Uniform gold spheres were only generated in ablation experiments, in which the laser penetrated only a thin layer (12 mm) of water on top of the gold foil. For thicker layers of water, the ablation process resulted in gold spheres of varying sizes between 100 and 7 nm with a tendency to form nanoaggregates. The...
