A new breast cancer research study in mice examined the effectiveness of a mouse antibody, MAG-1, alone on human breast cancer cells transplanted into mice.Â For this study, mice were transplanted with either hormone sensitive human breast cancer cells or triple negative breast cancer cells and then treated with either a short-term (4 doses over 6 days) or longer-term (daily dose over 16 days) antibody-based immunotherapy.Â The study investigators reported that:
- Short-term antibody treatment substantially reduced the size of both estrogen-sensitive and triple negative breast cancer tumors.
- After short-term treatment was stopped, breast cancer tumors started growing again.
- Long-term daily treatment with the mouse antibody dramatically shrank both types of breast cancer tumors.
- Breast cancer tumors treated long-term did not start to regrow during the 20 days of observation after antibody immunotherapy was stopped.
- Examination of the breast cancer tumors showed that nearly 70% of them underwent extensive cell death after immunotherapy.
While safer and more effective breast cancer treatments are needed for breast cancer patients, it is also important to remember that there are things we can do ourselves to reduce our chances of developing breast cancer.Â Read my book Fight Now: Eat & Live Proactively Against Breast Cancer to learn about some of the things you can do.
