[Python] Can't find why my code isn't exiting the loop and printing

I'm attempting to write code in python that will calculate the area and circumference from the radius. Whenever I run the code it just returns "Please enter a radius for calculation." Like it never breaks the loop and starts back from the while true.

import math

radius = input()
#Area
x = math.pi*radius**2
#Circumference
y = 2*math.pi*radius**2

while True:
print('Enter a radius for calculation: ')
try:
radius = int(radius)
except:
print('Please use numeric digit.')
continue
if radius < 1:
print('Please enter a positive number.')
continue
break
print ('The area is', x)
print ('The circumference is', y)


I'm expecting the output of the area and circumference. From what I can tell the break should end the loop and immediately run the print statements. But, it immediately returns to the while true I'm just at a loss for words.
