Hello wise mumsnetters! I am not sure if this is the right board to post on but here goes. Booked a holiday in March. Found a breast lump end May. Went to Doctors very end May - said it’s perfectly normal, I have lumpy breasts etc but will refer me on 2W pathway to hospital for reassurance (as they do with all breast lumps now). 2 weeks later (June) went to hospital where I had a biopsy & breast examination. 19th June I was diagnosed with breast cancer (still thinking I might be able to go on my holiday at this point). Due to surgery this became apparent it wasn’t going to happen or be advisable so rang insurers on 28th June to advise and formally submitted claim a while after (as GP took a while to do their part of the forms I needed). Claim has now been rejected as I should have told them “in a reasonable timeframe” that I was under medical investigation (and paid more ££ for the cover to be upheld). My thoughts are that the timeframes here are still highly reasonable - I could understand if I’d been having tests since April but everything happened so fast! I was wondering does anyone have any advice on how to challenge insurance claims or any positive insights on getting my money back? It feels really unfair!
