I have been feeling the heaviest in my life round my belly. Thought it was all due to bloating from The tamoxifen but turns out it’s a menopause thing! https://aaptiv.com/magazine/menopause-belly
I was menopausal way before cancer and to be honest had practically no weird or unwelcome side effects. One really heavy bleed and that was it. I sympathise with all those having unpleasant and unwelcome symptoms, but not everyone gets them.
