How can I buy Cancer Insurance in India?

I am looking for cancer coverage for myself and my family. Could you please tell me how can I buy Cancer Insurance in India?
I tried searching on internet but no luck so far. Please note that I am aleardy covered by critical health insurance.

It's good thing that you have already bought CI cover. In addition to that your Health Insurance Plan will also provide cover to Cancer. You can also buy following plans:
1- ICICI Pru - Cancer Care Plus
2- Indian Cancer Society - Cancer Insurance Policy
3- CPAA - Cancer Insurance Policy

Thanks Matrix!
