Best comprehensive full body checkup for parents in Mumbai

I am 35 and have parents who turned senior citizens. I don’t stay with them and get to meet them once in a year or two. Recently both my paternal grandparents were diagnosed with cancer, my mom was diagnosed with severe arthritis in right knee and has a flaring pain in her right leg. She has consulted multiple doctors and all say different things. For their health and my peace of mind (given parent’s dont listen to anything we tell them), I want to get a full body check up done for both of them. I was thinking Hinduja but they have added Vitamin D and B12 in their most expensive package.

Looking for inputs for this community for the right place to get this done.

Please suggest.
