Answer:
Autonomy
Step-by-step explanation:
Autonomy allows the individuals to make independent decisions. In the case given in the question, the oncologist believes that the patient has the right to have their own opinions, values, and beliefs. This is why the doctor has left it on the patient to decide whether they want to go for chemotherapy or radiation to get rid of the disease. Autonomy gives the patient the right to accept or reject any treatment for themselves.
