Now, a team of researchers from the University of Otago and the Mackenzie Cancer Research Group in New Zealand are developing a 3D bioprinting process to create a new 3D structure with breast cancer cells to help develop new breast cancer treatments. The study was funded by the Cancer Society. 
“Usually, we culture cells on a 2D plate and they grow into a single layer. Now, what we are doing is cultivating cells in a 3D environment, which is more realistic. Compared to 2D cancer structures, 3D cancer The structure reacts very differently to chemotherapy drugs, which means we can try to develop many different, more targeted drugs," the researchers explained. Currently, they are studying how chemotherapy drugs affect 3D bioprinting cancer structures. 
The details of the bioprinting process have not been disclosed too much, and we know that New Zealand scientists are using a build-up system and cancer cells to create a tumor-like structure. The research is still in its early stages and one of its main goals is to achieve personalized cancer treatment. 
Specifically, one day, researchers can use a patient's cancer cells to print a tumor in 3D, and then use the structure to test the most effective drugs and treatments for this patient.
With proper adjustment, this 3D bioprinting process is equally applicable to other types of cancer cells.
