Brownlegs - diagnosed with DCIS for second time and insurance company refused to pay out again

Morning 

I was diagnosed with DCIS for the second time -and had to have my breast removed and now on chemo tablets . Legal and general refused to payout again approached the ombudsman who sided with legal an general. What more can I do? Just get diagnosed with terminal illnesses?  It really has affected my state of mind on anti depressants which is not helping either
