Ditto what Mrs DV and Devora said.
DS's adoption was chronologically second to my fertility treatment and anyone who knows him would understand why he is not any more second best than any other child in this world and in my very humble opinion is in fact way, way more amazing a child than any child I could have produced biologically (though I am prepared to concede that I may be a tad biased!).
But adoption is different. It is. Not better or worse but different. I have fantastic things in my life because of adoption - DS, humility and empathy (which a few posters here seem a little lacking in!), wonderful people whom I met as part of our adoption (before during and since). Life is great. But I have also missed out on things as has DS, providing my child with good pre-natal care, one to one attention from birth, knowledge of his genetic roots and a sense of where he came from and a lack of being part of the mainstream, a constant pressure to explain, to justify etc. And I can never "fix" that for him. (sorry thats a bit of a ramble
)
But the OP is ridiculous to single out IVF. IVF costs the NHS around £60m a year - sounds a lot but unnecessary GP prescriptions alone cost the NHS over £8m a year, its estimated that failure to attend hospital appointment cost the NHS over £600m a year (even if you said only 10% of that might translate into true out of pocket costs rather than shorter waiting lists, that would alone pay for the IVF).
The total NHS budget is around £100 billion a year, cancer care accounts for around £5 billion of that.
I suspect there are many more profitable areas you could look to find more funding for cancer than IVF is that is truly your concern OP (colour me unconvinced by that but I can pretend
)
