What is the cut off point for medicine?

There is no one definitive cut off point that applies to all medical situations. The decision to stop medical treatment is usually based on a variety of factors, including the patient's wishes, the likelihood of success, the potential for harm, and the financial cost.

In general, doctors will recommend stopping medical treatment when further care would provide little or no benefit to the patient. This can include cases where the patient is terminally ill, where life-sustaining treatments are no longer effective, or where the patient simply no longer wants to receive treatment.

Financial cost can also be a factor in determining when to stop medical treatment. In some cases, treatments may be very expensive and the patient or their insurance may be unable to afford to continue them.

Ultimately, the decision to stop medical treatment should be made in consultation with the patient and their doctor. This is a personal decision that each individual must make based on their own unique circumstances.
