Immunotherapy is a treatment that could use certain parts of the immune system to fight cancer. The immune system may help the body to fight against infections and other diseases. A new way to boost specific type of tumor-fighting cells for bone marrow cancer has been identified by a research team from the VIB (the Flanders Institute for Biotechnology). The research study was mainly carried out by blocking a hormone-related mechanism that could suppress the immune cells. This could restore the tumor's ability to battle growth.
