Hi I am 18 years old and very concerned about this pain I m having in my right breast, it almost feels like it is underneath the breast but the whole area on the right side of my chest is hurting for the past 2 days. I m quite concerned about this, I am not pregnant or in a sexual relationship, so I m wondering if I could have breast cancer at this stage in my life. Pleas do answer, I m quite unhappy and in pain right now, so please do tell me what is it and what should I do about it! Thank you.
