The point about women 40+ being assessed differently from younger women makes sense. What I'd want clarified before deciding, though, is whether a clinic's female cases are mostly pattern loss or also include diffuse thinning, since those seem to carry different risks. The listed options sound broad, but broad service lists don't tell you how a clinic screens candidates. Asking for actual female case photos and how many they perform per year seems more useful than the price range alone. A topper avoids surgery entirely, so I understand weighing that first.
