My Advice, dont take any insurance which offers a cover without full check up. They will reject a claim after eating up all the premium. Discloses everything and and take a cover. You will get a cover with higher premium.
You can take a health/life cover for your family irrespective of their work. The maximum assured amount might differ based on the earning though. Try acko for health to get a quote and idea. They are quick and helpful. Even if you do not choose them you will get to know the process.
I will reiterate again, disclose everything even if it means a higher premium.
1. I'm a senior insurance advisor. I will tell some insider information. We have a list what is called "Straight Decline". Cancer is one among them. But as you are saying you are doing fit and fine. We can try. But go through an advisor who really can help you. I'm not confident you will get it but I recently got an insurance approved for someone who had 3 surgeries in last 4 years without loading. Sometimes things do go in our favour. There are cancer specific plans available for cancer patients. Stage 4 is very likely a rejection. From your post I get a feel yours is not Stage 4.
2. Yes. But even with health check up, they don't test for cancers. I'm sure you know that Petct is needed for Cancer screening. And it costs close to 28k in a city. So companies can't afford that. You have to disclose pre-existing condition with or without health checkup
3. No such concept
4. Yes. Please DM me once. I want to give an advice that can't be said publicly.
