I have a giant lipoma on left side of my waist, it's there since 8 months, i hope it does not affesmy pregnancy!

No, it will not: A lipoma on your wrist will not affect your pregnancy in any way. They are benigh growths, so usually only removed , it large, unsightly or in the way. Good luck with pregnancy!

Benign lipoma likely: Lipoma is fatty tissue which is usually easily compressible; If a massive size, there might be difficulty; if the size is not massive, there is no reason why a pregnancy would be affected, as the pregnancy is almost always within the uterus which is muscular and protective.
