Biopsy is a waste of time & money and most importantly "hope". Doctors who advocate biopsy either don't know how to cure ec or they simply want to make a deep hole in your pocket. When Doctors fail to find the cause for ec and prescribe %¤#&!§-steroid ointments or worse "a biopsy" instead proves the point that they know absolutely nothing about ec....I have completely lost faith in Modern medical Science and would never recommend it to any body. am currently under ayurveda and keeping my fingers crossed...
