Hi hisnibs,

I work for a life insurance company and have a lot experience in this area. The first thing you need to do is know the kind of policy you have now. Why are you cancelling it? Find out if there are riders on your policy that allow you to increase your coverage with having to prove insurability (no medical) If it's a whole life policy it probably get dividends and they can be used to increase your death benefit also.

It will be much harder to get life insurance with having cancer, there's no doubt. If a company does decide to insure you, you will most likely be rated which will make the policy more expensive. If you like I would be happy to answer questions you have. I do this everyday and I'm very passionate about it. I would hate to see you lose a policy that may be good to have.
