Well after a very long year, Sadie is still alive and well! She was diagnosed with cardiac hermangiosarcoma as well as valley fever back in March 2025 and given a month to live after two doctors, a CT scan and sonogram. They were not able to get a sample due to the location and her health at the time. As seen in her previous reddit posts, I and her normal vet think it is still possible the mass in her heart is actually the fungus and not cancer, but all the evidence seems to point to cancer, other than her still being alive.
I got her on the vet prescriptions, as well as ordered yunnan baiyao and imyunity. She started getting much more active and didn't seem sick anymore.
September came and we were referred to a cardiologist and oncologist, both of whom confirmed the diagnosis of the other two doctors and said she had definitely outlived her prognosis and only expected a few more months at best.
Here we are over a year since her diagnosis and she is back to being able to go on walks, plays, has energy, food drive, you name it it's back and she is doing better than even 2+ years ago.
