To not understand HOW HRT can possibly increase your chances of getting breast cancer 10 years after stopping it?

[Ligresa]

Oestrogen declines and/or stops. Hence HRT

When Hrt stops, then oestrogen and progesterone stops.

How then can cancer caused by hrt be triggered years later?

Are they saying that hrt changes your body on a molecular level? Which then means you are more likely to get cancer?

Just trying to get my head around it !

Is the same effect if you started periods early or had a later menopause, the cancer doesn't start immediately after natural menopause.
Effect is a 2% increase in risk whereas obesity is an 8% increase in risk as is smoking.
CRC website explains the statistics very well

It's correlation.
Causation hasn't been proven.

This is older research, which has been re-data-mined and the data reanalysed along different lines to come to a slightly different conclusion to the previous one. The value of the conclusion is debatable. If I was taking HRT, I wouldn't stop purely due to this report.

So if I go through menopause at 49, and my friend goes through menopause at 53 who is more likely to get breast cancer at 60?

Surely these results make no sense?
