Hi Vickimarie, our family travelled to the UK earlier this year and were insured by Medibank Private Travel Insurance. They offer automatic cover for breast cancer based on the following (from their PDS):
Breast/Prostate/Kidney/Bowel/Colon Cancer – If You
were diagnosed over 6 months ago, have not had any
chemotherapy or radiotherapy in the last 6 months,
Your cancer has not spread beyond the primary site
at any time and Your Journey is less than 6 months.
In respect of prostate cancer You must also have a
Prostate Specific Antigen (PSA) of 10 or less.
Might be worth investigating. Best of luck with it. Jane xx
