What it is
A mastectomy for breast cancer performed under general anaesthesia using a potion of thorn apple, monkshood and other plants, 42 years before ether was used in Boston. Hanaoka operated on more than a hundred patients this way.
As it was not published outside Japan, it had no influence on Western anaesthesia; his mother and wife took part in the trials, and his wife went blind as a result.
What it led to
- cancer surgery in Japan
- Hanaoka's surgical school
