hi if your friend has man boobs then yes he can have a tumor so get and help him asap. good luck
can a mammogram detect whether a lump found in the breast of a male is fat cells or a tumor? . a male friend of mine has been advised to have a mammogram even though a biopsy already ruled out cancer in a lump he found in his breast. the doctor indicates he is not certain if it is fat cells or a tumor. can a mammogram detect this? and why would they not already know this information from having performed a biopsy?
