I am in high school and am a cancer survivor. Can I still join the military?

I am cancer survivor (thank God) and in high school and I would like to join the USAF one day as enlisted. I have asked this question many times before but half of the answers I get is ``no you cant join``, then I get ``yes you can``. PLEASE anyone, I need a straightforward answer. I get so discouraged when people say I can`t then people say I can join. It gets confusing. The cancer was Hodgkin's lymphoma. I have also had asthma but I never had to use an inhaler since 6th or 7th grade and it does`nt affect me when I exersize. Answers are very appreciated, it means alot
