[|Human|] I have a small lump on lower backside of my head on the left side about 1 inch above my hair line. It feels hard at touch and is size of grape maybe a little smaller. the area is tender and when i noticed i pushed on it and there was local pain. Any options on what this could be.
[|AI|]  Hello! Thank you for the query. At this location, sebaceous cyst is the most probable reason of this lump. It's a benign soft tissues' tumor filled with whitish masses. It does not turn into a cancer. However, it may get infected. If so, it becomes tender, swollen. Sometimes in mentioned location enlarged lymph node can also appear. I suggest you to consult general surgeon with this issue. Soft tissues' ultrasound should be done. Sebaceous cyst should be removed. If its enlarged lymph node, biopsy should be considered. Hope this will help. Regards.
