Ralgyz Plus 250mg Softgel Capsule

I am a male of age 76 as on today. I am a patient of cancer of urinary bladder. Initially in March April 2016 I was having blood in urine. After detailed examination including MRI, Biopsy and CT scan it was diagnosed as Cancer of Urinary Bladder. I was operated upon (TURBT). PET CT in Sept 2017 shown tumor of 38 mm. Then I was treated with chemotherapy from 01 Oct 2016 to 06 Jan 2017. On 08 Jan 2017 PET CT revealed tumor reduced to 8 mm. Radiation was done upto 10 March, 2017. Doctor put me on Tab Ralgyz Plus -1 OD. PET CT done in June 2017 shown a little reduced thickening than earlier outside right side of Urinary bladder but it was non cancerous. Tab Ralgyz Plus continued for 3 months. On 06.12.2017 PET CT shown even better results. But thickening was reduced still there. Doctor again has put me on Ralgyz plus from 10.12.17 onwards. I am now having blood in urine with little chips of white color. Tests like Lipid profile, Renal profile, Lever profile, CBC and Urine culture were done. All tests shown normal result except Urine, which was sterile after 48 hours but RBC were seen (full field). He is also on clopiwas for blood thinning. On stopping clopiwas for a while RBC in urine fell to 20-25 and colour was also visibly normal. Please advise. PET CT on 06.12.17 shown no cancer. But after 15 days blood is coming in urine. Is it because of Tablet Ralgyz plus or due to cancer coming again? What should I do now?
