I have no idea how this dilemma can be resolved but my oh is on zoladex and is in the middle of his chemotherapy treatment ( he has already had radiotherapy, hormone treatment and arberatitone ). We have noticed that he has been affected more with each treatment and has very little energy so we are very worried about the danger of his contracting the virus. It is hard but we have decided to minimise contact with other people, even family, for the time being.
Only your medical practitioners can really advise you as it will depend on many factors, including age, general health and progression of the cancer.
I wish you both all the best and hope you stay well.
