If I get a recurrence, I reckon it will because about 30% of us will get a recurrence anyway, irrelevant of the diagnosis/staging & the good outcome of your surgery & treatment - I don't really think it will because I am drinking, vegan or whatever ....
Having said that - everything in moderation is my 'catch cry' .... I enjoy a wine & the odd Bundy & Rum, even a beer now & then - but there may have been a few more Bundy's in recent months ..... Hubby's recurrence was definitely not due to booze. He's never been a drinker.
I've got 2 buddies who've had serious Dupuytren's contracture (all successfully operated on & hands working fine now.). Both used their hands strenuously, one had a lifestyle change & became a therapeutic Masseur - and within 12 months, developed it really badly on his ring finger of one hand. They are the only ones in their family to have it too - but I suppose it has to start somewhere? Same as my BC - I'm the only one in the immediate family to have it and as I don't have kids, won't be passing it on, that's one thing for sure! I've recently heard that a first cousin was diagnosed last year too.
@Jwrenn - is there a genetic test/chromosone that can identify the link in your family - specially as one sister doesn't have it? Could be worth looking into if some medical person wants a research project?
Take care, xx
