Thyroid & Parathyroid Surgeon in Los Angeles
Board-certified surgical oncologist Dr. Jason S. Cohen is a dedicated thyroid and parathyroid specialist at Cedars-Sinai Medical Towers, offering focused, minimally invasive surgery of the thyroid and parathyroid glands for patients across Los Angeles.
A Los Angeles Specialist in Thyroid & Parathyroid Surgery
The thyroid and parathyroid glands sit at the base of the neck and control metabolism and the body’s calcium balance. When these glands develop nodules, grow too large, or become overactive, the right surgeon makes all the difference. As a fellowship-trained surgical oncologist and general surgeon, Dr. Jason Cohen has built a focused practice caring for thyroid and parathyroid patients throughout Los Angeles — combining precise, minimally invasive technique with the judgment to recommend surgery only when it is truly the best option.
Every patient is evaluated individually at Dr. Cohen’s office in the Cedars-Sinai Medical Towers, with attention to voice preservation, cosmetic outcome, and the fastest safe recovery.
Thyroid Conditions We Treat
Thyroid Nodules & Goiter
Most thyroid nodules are benign, but some require biopsy or removal. Dr. Cohen evaluates nodules with ultrasound and fine-needle aspiration and, when surgery is warranted, removes part or all of the thyroid through a small, carefully placed incision.
Thyroid Cancer
For papillary, follicular, medullary, and other thyroid cancers, Dr. Cohen performs thyroidectomy and, when needed, central or lateral neck lymph node dissection, coordinating closely with endocrinologists and oncologists at Cedars-Sinai.
Overactive Thyroid & Graves’ Disease
When medication or radioactive iodine is not the right path, surgery offers a definitive solution for hyperthyroidism and Graves’ disease.
Parathyroid Surgery for Hyperparathyroidism
The four parathyroid glands regulate calcium. When one becomes overactive (primary hyperparathyroidism), it can cause fatigue, bone loss, kidney stones, and memory changes. Dr. Cohen performs minimally invasive parathyroidectomy — often removing a single enlarged gland through a very small incision, frequently as an outpatient.

Thyroid & Parathyroid Surgery FAQs

No. Dr. Cohen uses a small, carefully placed incision in a natural neck crease so the scar is discreet and heals well. Many thyroid and parathyroid procedures are performed through incisions of just a few centimeters.
Many thyroid and parathyroid operations are performed on an outpatient or overnight basis. Dr. Cohen will review what to expect based on your specific condition during your consultation.
Not all nodules require surgery. Dr. Cohen evaluates each nodule with ultrasound and, when appropriate, a fine-needle biopsy. Surgery is recommended when a nodule is suspicious, growing, causing symptoms, or proven to be cancerous.
Primary hyperparathyroidism can cause fatigue, kidney stones, bone thinning, abdominal complaints, and memory or mood changes, often with an elevated blood calcium level. Minimally invasive parathyroidectomy is a highly effective, often outpatient cure.
