I've nothing to add except that if it was your normal practice to hug and cuddle her then I'd suggest, depending on whether she seems to want it ( obviously) still...that you make sure it's still available.

She's still the same person, no need to tiptoe or hold back on the usual loving approach.

Lot's of cancers are very successfully treated with mixtures of treatment. There may be every reason to be optimistic.

Your mum will need a fair bit of support to I imagine.
