Several calls  spam or scam  any body's guess.

I received a call from this number. They said it was for breast milk research and asked if I would make a one time donation if they sent me the supplies.

I just got a call and the woman asked for Tom. I said she had the wrong number. So then she said, "maybe you can help me" and broke into a pitch for women w/ beast cancer who can't afford their medications.

She called asking for Mike, i told her Mike is not available, how can i help? She was rude and said nevermind i will call him back

Got a call from this number on my cell phone.  Said she was collecting for breast cancer research.  I just hung up.
