Not only are side effects from some therapies decreasing, the overall mortality rates are also improving. I use MSKCC and AHA nomograms and predictions to assess my cardiac risk and PCa mortality risk.
I was diagnosed in 2018. My status today shows roughly a 9% 15-year mortality risk and a 7.2% heart attack risk (pre-PCa my heart attack risk was 14.2% - I started a statin and my cholesterol dropped 40%. I increased my exercise and cleaned up my diet and my blood pressure dropped, my heart rate dropped, my bodyfat dropped, and my blood glucose dropped).
