@Brenda5 .... you may help here?
It hasn’t happened to me, but i have One friend who ended up with a heart condition that was caused by her regime of chemo .... but it took some years to ‘show up’.
What treatment are you on? I put up a post about this subject a while back .... tho it depends on your treatment. Just be aware that chemo CAN affect the heart.
