So sorry to hear about your friend, but am happy for you to have found us.
I believe in gathering as much knowledge as possible, and this site will be a valuable tool in the quest for information, evaluating such and making informed decisions due to the vast knowlege others have accquired while encountering this disease.
Of course, you might want to encourage your friends to collect all medical records, physician diagnoses, scans, blood test results, etc. in order to approach those medical institutions and physicians, who have been treating a higher volume of CC patients for second, third or even more opinions.
When entering key words in the "search" function on this site, you will find that many questions you might have, others have already addressed. Reading through the posts is time consuming, but may proof itself to be highly informative.
Don't hold back from asking questions, may it be in the quest for navigating this site or anything else coming to your mind.
Wishing for the absolute best for your friend
