If you read the summary posted by Stressy-messy (thanks for that) it is clear they are not just talking about DCIS - here is the extract:
"129 cases of breast cancer, invasive and non-invasive, would be overdiagnosed"
So are they also talking about Grade 1 cancers? As someone who had both DCIS and grade 1 invasive, mx because they were behind the nipple and rads because they couldn't get clear margins on one area of DCIS, was I overdiagnosed? Actually, I'm relieved I've been treated. The key for me is the definition of overdiagnosis:
"which is defined as cancers detected at screening that would not have otherwise become clinically apparent in the woman's lifetime"
I was diagnosed at 61 and provided I don't fall off Striding Edge or otherwise suffer an accident I expect to live to 90/95 based on general motality rates, my lifestyle and family genetics. So my lifetime could be longer than many, bc aside. I have just taken my 87 year old mother to see her oncologist, she has lung mets. She was diagnosed at 85 and has had an mx, rads, Xeloda and is now on paclitaxel. She can't cope with the treatment, can't eat and is down to 6.5 stone and can hardly breathe, and I wouldn't put a dog through what she is enduring but she is of an age where she believes doctor knows best. If it's offered she'll take it. My grandmother was also diagnosed at 87 but was too frail for surgery so was given hormone therapy. Quite frankly, I'd rather have the treatment at 61 when I've been able to cope with it than take the risk it finally appears when I can't.
To sum up, they don't know which cancers will become "clinically apparent", and a "lifetime" is subjective, so all in all I'm glad I did it. But it was my choice.
