This study watches 25 people with breast or lung cancer who are getting immune checkpoint inhibitor therapy. Researchers use heart scans and blood tests to see if the treatment harms the heart's tiny blood vessels. No new drugs are given; the goal is to learn how to better protect patients' hearts.

- If successful, this study could help doctors understand how to monitor and protect heart health in cancer patients receiving immune therapy.
- What could go wrong
- This is a small observational study with only 25 participants, so results may not apply to everyone. It does not test any new treatment.
