Study Summary
This clinical trial evaluates whether engineering gut microbiome using probiotics will alter the body's immune system to react to stage I-III breast or lung cancers that can be removed by surgery (operable). Having diverse species of bacteria inside the bowel may help improve the immune system, particularly the ability of the immune system to recognize cancer. Taking probiotics may change the diversity and make up of the bacteria in the bowels, and change how the immune system reacts to breast or lung cancer.
Primary Outcome
Will be collected via study diaries.
Interventions
- PROCEDURE Biospecimen Collection
