Hi Jane70
Dancinggirl has helpfully given you most of the information you need. I just want to add have you read the information on this site? The menu on the left - summarises a lot about risk and cancer, age etc The sub-tabs - especially under HRT (second heading down on the green menu) are very helpful eg balancing risks and benefits here:
http://www.menopausematters.co.uk/balance.phpIf you look at the scales for age under 50 you will see that the official view is that the benefits exceed the risks. I agree that you really need HRT! I wouldn't cut the patch - you are incredibly young to be having HRT and I would want at least a medium dose of 50 mcg (patch) which is what you have at the moment.
Personally I would definitely stay on patches in the long term, but as Dancinggirl says you may need to change if the progestogen disagrees with you.
Firstly it is usually better in my opinion to start with cyclical HRT wherever you are in menopause because then you can determine whether the progestogen is causing the problem - but of course the disadvantage is having a cycle and the hormonal fluctuations ( in progesterone) - and therefore pmt - that comes with that.
So if you stay with patches you would be better off eventually with a separate oestrogen and progesterone ( micronised progesterone - Utrogestan) because the combi patches have synthetic progestogens that can cause side effects.
Incidentally it is increasingly being thought that the effect on the breast differs according to whether synthetic or "natural" (ie bio-identical) progesterone is taken. I don't have the research info to hand. All the risk statistics quoted are from studies using synthetic oral progestogens and equine oestrogens.
In your case, as you are young, and had an early menopause
http://www.menopausematters.co.uk/menopause.php I would go for as higher dose as I can cope with - re progestogens - because higher oestrogen doses require higher progesterone doses to shed (or protect) the womb lining.
I am 61 and use Estradot 50 mcg patch with Utrogestan 200 mg for 12 days every 6-8 weeks ie still have a cycle and bleed and I have been using HRT for over 7 years now.
I hope this isn't too rambling!
