Maybe you choose to go private for mammogram every year?

I'm not 100% sure, but I think after confirmed breast cancer you're entitled to annual NHS mammograms (whatever age

I think it depends on your local health authority. I was diagnosed with ductal and lobular cancer in the same breast, although initial diagnosis was just ductal breast cancer.
While I'm grateful for full surgery, chemo and radiotherapy and subsequent bi-annual mammograms, unlike you growstuff, I have not been able to have my remaining unaffected breast reduced to match the operated breast. I've not had half of the 'extras' you've been gifted, which just goes to show it's still very much a postcode lottery, despite my mother and a niece also having breast cancer.

I'm not 100% sure, but I think after confirmed breast cancer you're entitled to annual NHS mammograms (whatever age).

Even annual mammograms don't always pick up slow growing cancers and they often miss lobular cancer completely.

I'm part of a personalised breast cancer programme, so my whole genome has been mapped. Genetic testing is different. I was offered it, but declined, as my daughter and sisters said they wouldn't want to know the results anyway.
