like what devilish_me mention, its gd to get a IFA, and ask for multiple quotes from different insurer, and compare them.
Many people read the terms and conditions of the contract, but without being able to compare them, they are just information. Example, some TPD is define as complete severance of the limbs. Reading this, means nothing, but compare with another who define TPD as lost of effective use of limbs, will mean big difference.
Cancer is define in multiple stages. benign cancer also have stages, classified as in situ in 3 stages, then malignant can have have 4 i think. those are invasive. Insurance CI will cover the malignant cancer (invasive).
Some people like to buy the early stage caner (benign). Such plan are costly simply becos, the risk of such claim is much higher compare to malignant. The high premium paid, does not mean full payout as well. Its a percentage of the sum assured depending on the illness. I wonder how many times of benign you wish to contract in order to claim all the sum assured (touch wood). In term of cost, its not worth, as benign medical cost are not that huge compare to malignant. Alot of people only have a fraction of the major CI, and waste $ to buy early stage. But they forget which is the one that really cost $ in the real case.
Such early cancer plan will be suitable if the individual has already sufficient CI coverage, and with more budget to cover the early stage.
