A raised mass in the back area may be a localized soft tissue mass, such as a lipoma or sebaceous cyst. It may also be a bony mass in a localized area. You can go to the hospital to see a doctor who will make a preliminary judgment based on physical examination. If a soft tissue mass is considered to be localized, ultrasound examination can help determine this. If the mass is considered to be a bony mass, local CT and 3D reconstruction of the skeleton need to be improved, which can accurately determine. Further treatment will be done according to the results of the examination. If the mass is a lipoma, sebaceous cyst or other masses, there is no significant impact on normal life can be followed up and observed, or local surgery can be removed. If it is a bony mass, puncture biopsy is needed to determine the nature if necessary.
