[|Human|] i have a lump in the center of my chest. it has been there for 1 week. no pain .it doesnot feel hard. i can see it in the mirror when i stand up , but it doesnot feel hard. when i lie down i donot feel anything.age 58, weight 152 5 ft., donot drink, smoke, i take no medication. no heart problems, no hypertension.
[|AI|]  Hi.it is best if you consult with a doctor, preferably a general surgeon, for medical and physical examination. Based from your description, it could be a cyst (a sebaceous or a gelatinous type), a fibrous or a lipoma. These lesions can occur anywhere in the body and have the tendency to recur.  Management (medical and surgical) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.
