A lot of this is aimed at specialists. There are some useful bits about preconception counselling in a woman who’s had breast cancer and also advice about breast feeding. The most useful things are:
New presentation of breast lump – ensure you refer women as you would if they weren’t pregnant. Women can have treatment (including some chemo) whilst pregnant.
Contraception matters – generally non-hormonal methods would be advised first. They advise seeking specialist advice if a woman wants to use hormonal methods (they are absolutely contra-indicated until 5 years of being disease free). This includes Mirena use.
