has anyone been diagnosed with cancer while pregnant? did everything turn out ok?

a little backstory: my grandfather has been diagnosed with melanoma. I've read online that it can run in families. my mom had a mole appear on her face about 6 years ago and refused to get it checked. I've since cut off all contact with her for other reasons so I have no idea what is happening there but I'm assuming she still hasn't gone in to get it looked at. I'm currently 38 weeks pregnant. at 35 weeks I noticed a new mole on my cheek. It is all one color and symmetrically round so I told my husband we would just watch it. well tonight I found two more new moles. one on my other cheek and one under my left breast on my torso. the one on my cheek is also all one color and round but the one on my torso is oval and two different colors. I will bring it up with my dr when I see her on Tuesday morning but I needed to get this all out somewhere. Its 1:30 am here and everyone is asleep so I have nobody to talk to. I cuddled up with my husband and just cried so I left the room before I woke him up. he lost his mom to cancer when we were just 17 and hes worked his ass off to take care of me since we met (age 15). I have fibromyalgia and he took on the extra work load so I could stay home with our kids and take care of myself and my pains. I sure hope this turns out to be nothing because my husband is literally the BEST man on this planet and doesn't deserve to have to watch someone else he loves go through the cancer nightmare. I'm also worried about my unborn baby boy and how he'd be affected if this turned out to be something. sorry for the long post. I just needed to write this out somewhere. needed to get it off my chest so I could stop crying so hard.
