Mastectomy at 25

Hi guys, I’m 25F. Last year i had breast cancer due to which i had to get complete mastectomy of my left breast. I’m don’t with all treatment and I’m in clean now. But now i will have an implant put in without nipple as my left breast. I am very conscious of getting intimate with guys now, to even tell them about the whole thing.

My right breast is absolutely normal, I’ve joined dating apps and have started going on dates but I don’t understand what would be the right time to tell the guy about my surgery?

I don’t want to tell them too soon cause it’s too personal, I’m scared what if i start liking him and then tell him but he is not interested post knowing about the surgery.
