Health insurance can help cover medical costs or repay the cost of private treatment. Some health insurance policies may include payments towards wigs and prosthetics if you need this.
If you are recovering from cancer, your insurance may exclude claims relating to your illness. But unrelated conditions that develop after you have taken out a policy do not usually affect your cover.
If you do not already have health insurance, it could be harder to get if you have cancer. The insurer may ask you questions about your health or the health of family members. They use this information to assess if you are likely to make a future claim.
