<human>: My father in law attaining age of 75, suddenly he is feeling pain in his left nipple. There is little lump that can be felt when I touch that area. there is no pain in the lump area but paint is felt only on nipple. He is normal healthy person with  slight high pressure.
<bot>: Hello! Thank you for asking on Chat Doctor! Regarding your concern, his symptoms may be related to an infection or inflammation of the soft tissues of his breast. I recommend consulting with the GP for a careful physical examination, a chest x-ray study and some blood lab gets : -complete blood count-PCR, sedimentation rate (inflammation). A chest CT scan and biopsy of the lump may be necessary to determine the nature of this lesion. Hope to have been helpful! Best wishes,
