Doubtful. The actual study has not been posted but the press articles suggest that is not the case. You are correct that early intervention is being downplayed, but early intervention has downsides, mainly surgical trauma. Some people do well (you appararently are one) and some do not after such trauma.
As one example I have seen many cases where "weight loss surgery" results heart failure down the road. Rearranging how the body functions has a major impact on the body. Breasts might appear optional but that's not what the body works.
As for the early versus late cancer, that is a whole nother debate and I don't think it applies to this study.
Sadly, as usual, the media gets it wrong. They always do. Here's a link to the original article: Journal of the AMA.
Notice that there are other details, just in the summary alone, that the press isn't covering. See my two posts above for more information, too: It's been known for many years that lumpectomy with radiation has the same results as mastectomy IF the patient is eligible for a lumpectomy. Not all patients are. Yet, because the media only gives readers half the story, many people believe every woman is eligible for the less intrusive surgery.
