I'm feeling anxious about a hard lump I've noticed in the upper left area of my chest, close to my left breast. It feels almost like a bone or something solid just beneath the skin. Whenever I touch it, I'm reminded of how hard it is, and it's got me pretty worried. Could it be something serious? What might be causing this?
Surgeon opinion is advised to the patient. USG of the lump,FNAC and microscopy for mitotic cells , biopsy and complete blood count ,esr and C-reactive protein is advised to the patient.
