Recruiting studies in California
- NCT06092892RecruitingPhase 2
Upfront targeted lymph node removal for early breast cancer
This trial is for women age 45 and older with early ER-positive breast cancer that has spread to the lymph nodes under the arm. It tests a surgery approach where the main tumor and only a few key lymph nodes (rather than many) are removed.
Los Angeles, CaliforniaAges 45 years+ - NCT07147166Recruiting
Testing a device to prevent raised scars after top surgery
This study tests a special bandage-like device (Brijjit) that may help reduce thick, raised scars after gender-affirming mastectomy (top surgery). If you are having double incision top surgery and want to see if this device can give you flatter, less noticeable scars, this trial may be a good fit.
San Francisco, CaliforniaAges 19 years+ - NCT05444361Enrolling by invitation
Ultrasound freezing treatment for pain after mastectomy
This trial tests a “freezing” nerve procedure guided by ultrasound to help reduce pain after mastectomy. It aims to lessen postoperative pain by temporarily calming specific nerves involved in chest wall sensation.
San Diego, CaliforniaAges 18 years+ - NCT05794321RecruitingPhase 2
IV tranexamic acid during gender-affirming chest surgery
This Phase 2 study tests whether giving tranexamic acid through a vein during gender-affirming mastectomy can safely reduce bleeding. It may help lower blood loss and related complications during surgery.
San Francisco, CaliforniaAges 18 years+ - NCT05975359Recruiting
Testing a fluid-drain device during breast implant reconstruction
This study tests a new way to measure and manage fluid drainage during immediate breast reconstruction with implants. It may help surgeons reduce complications and improve the reconstruction experience after mastectomy.
Palo Alto, CaliforniaAges 18–65 - NCT07071896Recruiting
Video exercise program for breast cancer survivors
This study tests a video-based exercise program for people who recently had breast cancer surgery. It aims to help with recovery by providing guided exercises you can do at home.
San Diego, CaliforniaAges 18 years+ - NCT06502353Recruiting
Plexaa before gender-affirming mastectomy
This trial tests a product called Plexaa, which is applied before surgery to help prepare the skin and improve healing. It is for transgender or non-binary people having a specific type of mastectomy (breast removal) for gender affirmation.
Palo Alto, CaliforniaAges 18 years+ - NCT07463430Enrolling by invitationPhase 4
Suzetrigine for pain after non-mastectomy breast surgery
This trial tests a new pain medication, suzetrigine, for people having breast surgery (not mastectomy) who are expected to have moderate pain. It checks if this drug works well compared to standard options.

What taking part in a mastectomy study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
Common questions
- Are there mastectomy clinical trials in California?
- Yes. We're currently tracking 8 recruiting mastectomy studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a mastectomy study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a mastectomy trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
