Fit and Frustrated

I keep thinking it’s ironic I ran my first ever marathon, I got a ballot place and chose BCC as my charity raising lots of money which spurred me around the 26.2 miles. Never for one minute thinking it would happen to me. I’m youngish very fit healthy don’t drink or smoke and no risk factors.
So I’m really frustrated as what more can I do to prevent reoccurrence.
I came off anti depressants last Sept and feel strongest I have in ages, signed up for races throughout year. Now wondering will I still be able to run etc
I have surgery on 24th but unsure until 2 weeks after what treatment I need so feel my life on hold.
Sorry just really feeling frustrated today x

really sorry to hear this. Sadly although risk factors raise your chance of getting breast cancer, as you have found out you can get it regardless. How quickly you recover will depend on what treatment you need, but it is possible to get back to a really good level of fitness. I hope for good news for you after your surgery.
