Overall, 90% of patients with a CD4 count of 0 cells/μL – 200 cells/μL, 56% with 201 cells/μL – 500 cells/μL and 42% with 500 cells/μL – 1000 cells/μL exhibited advanced stages of breast cancer at the time of first staging, thereby demonstrating an inverse relationship. This evidence concerns the gene CD4 and breast carcinoma.
