Hi. I'm 17, 5 feet and 8 inches, and I weigh 120 pounds. I get stomach aches and nausea every night. Is this normal? I also get sick very easily (I'm sick right now). My medical history is nothing crazy. My grandpa died of a heart attack, he had diabetes. And my grandma died of cancer. I am also paranoid that I might have breast cancer, but I am too scared to get it checked out. I've felt my breasts before, but I can't tell if I have lumps or if that's just how my breasts are, because I've had one lump in each breast since I've developed them. One time before I went to shower, a little bit of puss came out of my left nipple, it made me worried but I don't want to go tell my mom this. Anything suspicious? Any advice?
