Well....after re-reading your first post I am less than thrilled that the doctor has let you walk around with multifocal cancer and delaying treatment. Mike's reply to you that 3 months go by between ct scans, well that is follow up for those who have just undergone bladder removal.
It is also common to wait 3 months between cystos for the newly dxed/ superficial blc.
But T1 and CIS are dangerous and shouldn't be left to simmer.
Bladder cancer is notoriously understaged and second opinion on path reports can be seriously enlightening. I want you to be very sure about the exact stage of your cancer. BCG doesn't help T2 and up tumors.
This review mentions Lymphvascular invasion and hydronephrosis of the kidney as further risk factors:
"In a group of 422 patients from the University of Michigan, understaging was demonstrated in 43% of patients with superficial and non–muscle invasive cancers and 59% to 60% of patients with muscle invasive disease.[6] Within this cohort, 32% had evidence of lymphovascular invasion (LVI). Those patients with LVI had a much higher rate of understaging (87%) than those without LVI (46%). In multivariable analysis, LVI was the only independent predictor of understaging; patients with LVI had nearly 8 times the risk of understaging than those without LVI (P < .001)."

The following hair-raising article is about the hazards of delaying cystectomy with T1 tumors: 'Intravesical treatment: Hazard to bladder cancer survival?'
