Can surgeons force me to have an operation that I don't want?
As long as you are mentally compitent, no one can force to have anything done! you have to consent to any treatment is sugested to you, and consent should be given only if you fully understand the treatment, the risks involved and possible alternatives to the treatment.
No one person can force you to have anything done unless you agree to it. No matter what the end result you have to decide.
