Could a holiday symbol be helpful to cancer patients? Scientists want to find out.

Aberdeen University in the United Kingdom will conduct studies to test whether mistletoe injections can help boost the immune systems of breast cancer patients.

The goal of the research is to determine if mistletoe injections are helpful and for which patients.
