She added that treatment would have given Ms Shemirani an 80% chance of a complete cure.
The Cambridge graduate had initially consented to treatment, the coroner said, adding that “doubts about consent only surfaced after Mrs Shemirani became involved”.
The coroner said Ms Shemirani was being influenced by her own beliefs, her mother’s, her father’s and by those of a family friend – all who advocated the alternative treatment she used.
“I found Mrs Shemirani’s care of her daughter incomprehensible but not unlawful killing,” Ms Wood said.
“It seems that if Paloma had been supported and encouraged to accept her diagnosis and considered chemotherapy with an open mind she probably would have followed that course.”
Ms Shemirani’s mother tried to blame medical staff for her daughter’s death and has previously labelled chemotherapy as “mustard gas”.
Staff at Maidstone Hospital, where Ms Shemirani was diagnosed, the Royal Sussex County Hospital and paramedics all acted appropriately, the inquest found.
Neither her mother or her father – non-medical doctor Faramarz Shemirani – attended the conclusion of the inquest.
