I ventured onto a website called Quora. Fascinating site. People ask questions about pretty much any topic in the world. There are people who try and answer the query. Over the past year or two, I started answering cancer related questions. It has been a fascinating journey. At times, it worries me about giving answers to people I have no idea about, their circumstances, their medical background, what their doctor has said to them, etc…. but over time I have learnt to be generic but specific.
It does not seem to be a second opinion, but a generic opinion. There are several doctors on the forum trying to help people from across the world.
The site is nice and simple. Most people can navigate it without too many problems.
