Adrenocorticoid Hormones:

Protection against one particular research toxin (7,12-DMBA) has been noted with acute usage of 9mmol/kg calcium-D-glucarate ( 3 hours prior to and another dose 30 minutes prior to DMBA injections) which reduced tumor occurrence from 100% to 30% [7] and studies with more chronic loading have noted benefit with dietary supplementation of 75mmol/kg (of the diet, /kg bodyweight and 213mg/kg human equivalent). [1] [7] This protective effect extends beyond breast cancer and is able to attenuate skin cancer with either calcium-D-glucarate itself [22] or the main bioactive metabolite [23] (skin cancer is known to be able to be induced by DMBA [24] ) and may also extend to DMBA induced oral cancers.
