DIM and Sulforaphane as an alternative to drugs

I was diagnosed in 2021 with estrogen + breast cancer. Lumpectomy and no nodes involved. I had 16 treatments of radiation and was put on arimidex. The results of the drug I was hospitalized for very high all over the place BP, fast heart beat, chest pain, it throw my thyroid off . I can’t take the other drugs because I may have a rare protein that causes strokes. My family has a history of strokes. I also was diagnosed with multiple drug sensitivities and multiple chemical sensitivity. I was wondering if anyone knows about DIM and Sulforaphane as my doctors have no information on them and I was told …good luck! Feeling lost!
