NICE suggest that (1):

if breech presentation at term
- all women who have an uncomplicated singleton breech pregnancy at 36 weeks should be offered external cephalic version. Exceptions include women in labour and women with a uterine scar or abnormality, fetal compromise, ruptured membranes, vaginal bleeding and medical conditions
- where it is not possible to schedule an appointment for external cephalic version at 37 weeks, it should be scheduled at 36 weeks.

Diagnosis is by:

palpation
auscultation: position of the foetal heart
vaginal examination
ultrasound - able to determine type of breech

Treatment:

caesarian or vaginal delivery decision is based on the type of breech, any causative factors, and the results of pelvimetry etc
external cephalic version is possible, but this carries the risk of abruption
vaginal delivery must be carefully monitored and supervised by an obstetrician
often the decision is heavily influenced by maternal preference

Note that planned caesarian section had a lower risk for perinatal mortality and serious morbidity than planned vaginal birth in breech presentation (2) in a randomised trial comparing the two forms of delivery.
