Thank you for the query.
Such lump can be a lymph
node (which is can be present in this area), or benign skin lesion like sebaceus cyst
Lymph node is usually related to the recent infection of close to it area. Lymph node is usually smooth and movable.
Sebaceus cyst and lipoma are quite soft lumps. Both can be present in any skin area. Sebaceus cyst can give pain when infected. Lipoma does not hurt at all. Both lumps do not give any cancer risk.
The best way to diagnose it is to have an ultrasound
of this area. In case of lymph node, biopsy
might be necessary. Lipoma or cyst can be removed.
Hope this will help. Feel free to ask further questions.
