Accumulation is a huge issue in most chemo currently used. I am aware of an individual who was told that full body massages were helpful in driving toxins out of the body. Even though it was 6 months after chemo the person decided to give it  a try. Massage was scheduled for 1 hour, after 30 minutes the person stopped because of nausea, metal mouth, dizziness etc. At the end of 3 massages over 3 weeks no more toxin symptoms occurred.
