Unfortunately, your photo did not come through. I am unable to diagnose the problem without seeing the exact color of the spots and other features and placement of the disease.
Many issues are caused by overwatering, though. If it is overly wet in your area, you may need to improve the drainage in your soil. This article will help:

Cutting the leaves will not solve the issue. It can help stop new spread, but the disease will need to be treated within the soil and plant as well.
