My husband has been through the whole experience I have had with phyllodes, I have had 3 recurrences with phyllodes tumour. It is an emotional rollercoaster and I feel like my husband is the only person that fully understands the effects of having this for 7 years has had on me, I do get worried about recurrence and twinges and also checking myself regularly.
I would recommend speaking to your partner tell them how you feel and what your struggles are and they will support you and care for you anyway love you
