So chemo can have a negative impact on patients' immune systems, that is fairly long-lasting. This might contribute to resistance to chemotherapy.

Curcumin might be a good thing to test as an immune building treatment following chemo:

The problem is bioavailability. But a good question is whether any previous testing has used curcumin with bioperene, which increases bioavailibility. The study also mentions use of nanoparticles to improve bioavailabliity.
