No. In an ideal world we can save everyone, but we can't! We need to decide priorities and if we look to protect fully one group, another will suffer, unless you happen to have a magic wand. Even the CMO has said its about a balance!
Can you show me where 10% of all covid deaths have come from women in the 40-44 age group please as I don't think that can be correct, that was specifically the age group i mentioned in the 5,500 cancer diagnosis. (as if it was you would expect at least 10% or more to be in the 45-49 bracket and then over that in the 50-54 bracket...)
Now I am sure you are aware that cancer is a nasty thing and it kills a lot of people. I am happy to be corrected here, but if you don't diagnose cancer early enough it will kill you. Dare I say that if un-treated, cancer has a 100% mortality rate. So yes, even based on your numbers (which i think are incorrect), if 3,000 women aged 40-44 get Covid, 300 will die (I dispute your 10% but lets go with it), whereas if 3,000 women who would normally have been diagnosed with cancer dont get this diagnosed and treated quickly enough how many will die as a result (obviously a lot of factors here like type of cancer etc...) but we know that early screening and treatment saves lives!
And thats not to mention the 'hidden' deaths over the next 5-10 years as a result of a crashed economy.
