I always worry about articles like this, as they make claims that can often not be justified to many of our newbies.
So yes, herbals can be used, and "soy isoflavanes" seem to have a well documented low-level effect. But they are cheaper as an OTC menopausal treatment than as a magic breast growth potion.
Massage also can have an effect if linked to the above and not used in isolation.
But I doubt a topical cream will have any effect other than on your bank balance if it is OTC.
....so no...don't take the risk...see a professional.
