Thanks. I Am 69 Years Old. 162 Cm And 51

Thanks.
I am 69 years old. 162 cm and 51 kgs.got breast cancer 1-1/2 year ago, stage one, went through partial mastactomy,and radiation therapy (19 times), now taking femara once daily. recently I am having hot flash sometimes in the morning, that feeling scared me because I remember before the diagnose I had hot flash quite frequently. Is that side effect from femara and What is the chance that I would get cancer recurrence. Thank you.
