@melony good news ! I too had just Radiotherapy and hormone therapy.Radiotherapy was ok just a very busy time as you attend Monday to Friday every day and was a lot of travel and hassle looking for a park.The actual treatment each day is quite quick.
I had 16 rounds and thought I would have major skin problems as am very fair but it did not happen.You need to invest in a good cream which you use 3 times per day and more if you need it . I do not recommend Sorbolene. I used Calendula cream at the centre straight after each zap and it was excellent.I used Dermaveen at home as I had already purchased it .Many ladies on here are keen on MooGoo.I creamed up for about 3months.You need to be careful with UV on the radiated area I found as it seems to activate it.
I have been on hormone therapy - Letrozole/Femara which is an Aromatase Inhibitor for post menopausal women - for 9 months and am managing ok. Yes I get joint stiffness , occasional hot flushes and a tendency to the blues .I find a 1 hour daily walk helps a lot with my joints and my mood. The only really worrying aspect for me has been the spike in my cholesterol which was formerly good .Aromatase inhibitors thin bones which was also a worry for me as I started with osteoporosis and had an existing fracture so I have 6 monthly Prolia injections.
Hope some of the above helps.
