as lots of others here
53 years old, also linked with my mom/cancer (RIP), than got the 1st one last year because doc was saying i'd better to do it... (all is OK)
the exam itself was absolutly nothing (in my case), but drinking that sh*t potion the day before was an absolute nightmare (well, more near the end than in the begining)
next one is in (5) 4 years...
