I’d really like to hear your thoughts on this. Would you want a blood test to tell you that your treatment may be becoming less effective before anything shows up on a scan?
Would that make you feel more prepared, or would it create more anxiety? 💗

@Courtney_J I am getting very nervous and scared because the surgery is July 13, 2021. My parents both died this year so I dont have them to talk to. My mom died on Feb 16, 2021 with a sickness she was suffering for 18 months so i was dealing with that for the last months and then my dad had a major stroke 3 weeks after my mom passed away and he could no longer go back to his assistance living so we had to find a nursing home. We found one he was only in there 3 weeks and then he passed away on May 6, 2021. Right after all that I was diagnosed with cancer so I have been on a train that is non-stop. I feel like I am so tried out and I dont have much energy left. My sisters are not helpful they keep telling me just pray. They both got to take 2 weeks vacation after my mom and dad passed away. I have not even had time to take a breather I am just on the train of bad luck. That is how I am feeling.

Hi everyone 💗
Imagine going for a routine blood test and finding out that your breast cancer treatment may be starting to lose effectiveness, even though your scans have not shown progression yet.
That is the idea behind newer ctDNA or liquid biopsy testing.
For some people with advanced hormone receptor-positive breast cancer, these blood tests can look for changes such as an ESR1 mutation, which may indicate that the cancer is becoming resistant to certain hormone treatments.
The possibility of detecting resistance earlier could give doctors another opportunity to adjust treatment before visible progression appears.
But it also raises an emotional question.
Would knowing earlier give you reassurance and more treatment options, or would it create more anxiety while you are still feeling well?
💬 We’d love to hear your thoughts:
If this type of monitoring became part of your regular care, would you want every result explained to you straight away?
With care,
Razar from the Carenity team💖
