I have an appt for a mammogram in April. Never had one dr suggested I go as my breasts are dense. For the past 2weeks I've been feeling and pushing on what feels like a lump. I'm so sore from it but I can't stop pushing and feeling I run to the bathroom in public because I have to feel it. I can only really feel the lump when I'm standing up. Otherwise it feel just like me other breast but a bit firmer. I've felt it in every position imaginable and standing is when I can feel it. My breast aches and I'm so scared I have cancer I just don't know what to do. The lump is in about the one o'clock position and about an inch and a half up from my nipple it's squishy too when I push on it. Any help would be great as I'm scared to tears.

Thank you in advance

Joni
