My mum passed away recently. She had breast cancer like me. She was 73 and had chemo then went onto EC and completed one. Sadly she passed not long after this with a pulmonary embolism in her lung. She had a chest X-ray which was clear although she had pneumonia (according to the autopsy) and a recent blood transfusion. I just don’t understand why this happened? She complained of chest pain dizziness and was sick a lot. I blame myself because I should have helped or saved her.
