Of course. Getting a specialized cancer insurance cover over and above your health insurance plan is the right thing to do. Treating a deadly disease such as cancer can get quite expensive, and although your health insurance plan may cover cancer treatment costs, it may not always be enough to cover all of the expenses.
Also, regular health insurance plans payouts are based on hospitalization bills, whereas in the case of a specialized cancer insurance cover, the payout is made as soon as you’re diagnosed with the disease.
