[|Human|] I have  pea sized lump on my chest.  About a month ago, it was soft and pliable (painful to the touch).  Its now hard and has become slightly larger.  The tissue around it is soft and yet I can feel that this tissue is also beginning to harden.  Im thinking about a trip to my PCP....
[|AI|]  Hello there, Thanks for your post on Chat Doctor. I carefully read your query and understand your point of concern. I think this is an infected sebaceous cyst. It occurs due to accumulation of sebum. It is usually painless but when get infected it become painful on touch and hard. Furthermore, it has a black point on its top. I think you should go to a general surgeon for excision of the cyst after confirm the diagnosis. Hope it will help you. Wish your good health. Regards
