I have noticed a sore lump in the pit of my arm . It has been there for a little while, I m unsure if I can feel it in my right breast . Have been ignoring it, hoping it while go away. I m a 45 year old female. Should I be worried, or can this be a common swollen gland possibly. Haven t seen a doctor, a little bit in denial, and don t have a lot of time to think about myself with two children. Thankyou
