Subcutaneous nodules on the back are mainly seen in lipomas, follicular cysts, sebaceous cysts and other diseases. Whether the subcutaneous nodules on the back need to be removed or not, the correct treatment should be chosen after determining the nature of the subcutaneous nodules. 1. Lipoma: If the patient experiences discomfort, such as pain, it should be surgically removed. Lipomas should also be removed if they are large or growing too fast. 2. Follicular cysts: Follicular cysts may cause pain and itching in the hair follicles of the patient, or if there is a risk of cancer, surgical removal is recommended. 3. Sebaceous cysts: Sebaceous cysts are caused by obstruction of the sebaceous ducts, which leads to accumulation of sebaceous glands. Generally, sebaceous cysts need to be surgically removed. If the nodule is small and no obvious symptoms of benign lesions, generally do not need to be removed. If the subcutaneous nodule is large and at risk of malignancy, or has caused obvious symptoms, it should be surgically removed by a doctor in a timely manner. If you have subcutaneous nodules on your back, you should seek medical attention and standardized treatment under the guidance of your doctor.
