Critical Illness or cancer only policies

Hi wondering if any once had advice on critical illness cover; although not diagnosed genetic link my mum died at 48 from breast cancer (29 yrs ago) and my sister diagnosed at 37 hormone receptive tumour and is on tamoxifen further 5 yrs. I needed to review, due to a separation my insurance, and found that insurers will not cover me for breast or ovarian (although I am older then both mum and sister when diagnosed).

I am submitting an application to Ombudsman as the whole process LV kept moving the goal posts - if my sister was no genetic link I would get standard cover, then it became if I get tested and then it turned in to no cover commerically decision.

 

Any if any one had any advice on cancer only policies?
