Hello multiple swellings on body can be dermatoids, lipomas etc. which are benign tumors and may need obeservation without any treatment unless they increase in size and cause trouble like pain, bleeding, ulceration etc. As you told your diagnosis of mycosis fungoides is not confirmed. You can show it to surgeon and consider for biopsy. Biopsy is small surgical procedure which can be done in OPD and requires no admission. Biopsy does not spread cancer. It helps in differentiating benign versus malignant tumor. if tumor is benign and not causing any trouble no treatment is required. if its malignant then depending on type further treatment is indicated. All tumors does not require surgery. For example mycosis fungoides can be managed with steroids, PUVA therapy, local radiation or topical chemotherapy. Hope this answers your query. Thanks for posting
