hysterectomy early

So I am thirty and have masses (probably cancerous) on my ovaries. The probability the it'll spread even if the existing  masses are removed is pretty high. The doctor suggested a hysterectomy as a preventive measure. I have two kids already. But I, scared about the changes. So what happens? I've heard it's instant menopause. Skin ages 10 years. Lose sex drive. Breast tissue loosens (I can do reconstructive tho). Idk. Anyone have experience?
