Lymphovenous bypass for preventing lymphedema in breast cancer
This trial tests a surgery (lymphovenous bypass) to prevent or slow down lymphedema (arm swelling) in breast cancer patients who have already had lymph nodes removed. It may help those with early-stage lymphedema who haven't tried physical therapy yet.
Jakarta, Jakarta Special Capital RegionAges 18 years+ - NCT05920343RecruitingPhase 2/Phase 3
Preventing blood clots in genitourinary cancer with rivaroxaban
This trial tests whether rivaroxaban, a blood thinner pill, can help prevent dangerous blood clots in people with certain genitourinary cancers who are starting cancer treatment. It may lower clot risk, but it also has bleeding-risk tradeoffs that the study will monitor closely.
Ottawa, OntarioAges 18 years+ - NCT05432297Recruiting
Exercise program for people getting treatment for head and neck cancer
This trial tests whether a preventive, structured physical activity program can help people during and around curative treatment for head and neck cancers. It aims to see if exercise is safe and beneficial for strength, function, and well-being during radio(±chemo) therapy.
GothenburgAges 18 years+ - NCT05316922RecruitingPhase 3
Lowering thyroid hormone during radiation to prevent low thyroid
This study tests whether using treatment to keep thyroid-stimulating signals low during radiation to the thyroid area can help prevent a treatment-related drop in thyroid function in children. It is aimed at kids with certain cancers whose radiation plan includes thyroid tissue.
MilanAges Any age - NCT06341907RecruitingPhase 2/Phase 3
Vaccine and blood test to prevent ovarian cancer return
This trial tests a personalized vaccine for people with epithelial ovarian cancer who still have a small amount of cancer DNA in their blood after surgery. The goal is to see if the vaccine can help stop the cancer from coming back.
Wenzhou, ZhejiangAges 18–70 - NCT07699276RecruitingPhase 2
Steroid-sparing nausea drug combo for high-dose chemo
This trial tests if combining two anti-nausea drugs (olanzapine and palonosetron) can prevent vomiting and nausea without using steroids in people receiving high-dose cisplatin chemotherapy for their first time.
BangkokAges 18 years+ - NCT07127003Recruiting
Surgical bypass to prevent arm swelling after lymph node removal
This study tests a surgical bypass (called ILR) to prevent arm swelling (lymphedema) after removing lymph nodes from under the arm during breast cancer surgery. The goal is to see if this extra step helps keep your arm healthy.
Tampa, FloridaAges 18–75 - NCT05704166RecruitingPhase 2
Pirfenidone to prevent lung injury after breast radiation
This trial tests whether pirfenidone, a medication, can prevent acute lung injury caused by radiation therapy in people with breast cancer. You may be randomly assigned to pirfenidone or a placebo (inactive pill) to see which better protects the lungs during and after radiation.
Fuzhou, FujianAges 18–75 - NCT05557877RecruitingPhase 2
Low-dose aspirin to prevent postpartum breast cancer
This study tests whether taking a low dose of aspirin after childbirth can lower the chance of developing breast cancer later. You may be asked to provide blood, urine, and breast tissue samples so researchers can look for changes that could explain why aspirin may help.
Scottsdale, ArizonaAges 18–45 - NCT06268665RecruitingPhase 2
Tart Cherry Juice for Preventing Nerve Damage from Chemotherapy
This study tests whether tart cherry juice can help prevent nerve damage (peripheral neuropathy) caused by the chemotherapy drug paclitaxel. Participants drink tart cherry juice daily during their 12 weeks of paclitaxel treatment.
Sacramento, CaliforniaAges 18 years+ - NCT06427824Recruiting
Health tests for older adults with bladder cancer before bladder removal
This study looks at how a series of health tests (called a comprehensive geriatric assessment) can help doctors plan care for older adults with bladder cancer who are having their bladder removed. The goal is to improve recovery and quality of life.
Chicago, IllinoisAges 65 years+ - NCT05530655RecruitingEarly Phase 1
Finding the best lisinopril dose to prevent urine side effects
This early study tests which dose of lisinopril works best to help prevent urinary toxicity (urine/burning/urinary side effects) after radiation treatment for prostate cancer. If it’s effective for you, it could make radiation easier to tolerate.
Rochester, New YorkAges 18–70 - NCT06603870RecruitingPhase 4
Preventing repeat blood clots from IV catheters in cancer patients
This trial tests whether continuing a lower dose of blood thinners can prevent another blood clot in cancer patients who have had a clot in an arm or chest catheter. It may help find a safer way to prevent future clots.
Ottawa, OntarioAges 18 years+ - NCT07059884Recruiting
Exercise program to help people with cancer stay active
This trial tests a distance-based exercise program designed to help people on chemotherapy maintain their physical function and prevent disability. It is for patients with certain cancers who are working full-time and can participate in moderate physical activity.
Dublin, CaliforniaAges 18 years+ - NCT07849088RecruitingPhase 2
Chinese herbal medicine to protect kidneys during radiation therapy
This study tests a traditional Chinese herbal medicine (called Zhixiao Tongmai Ning) to see if it can protect your kidneys from damage caused by radiation therapy. If you have kidney cancer and are receiving radiation, this treatment might help keep your healthy kidney tissue working better.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05865743RecruitingPhase 3
Antibiotic cloth before surgery to prevent esophagus infection
This Phase 3 trial tests whether using an antibiotic decolonization treatment around the time of esophagus surgery can reduce serious infections afterward. It may help you lower the risk of postoperative infectious complications after curative esophagectomy or esophagus reconstruction.
LeuvenAges 18 years+ - NCT07160686RecruitingPhase 3
Blood thinner trial for lung cancer patients on treatment
This trial tests if apixaban, a blood thinner pill, can prevent dangerous blood clots in people with advanced lung cancer who are receiving outpatient chemotherapy or other systemic treatments. It aims to reduce the risk of venous thromboembolism (blood clots in veins) during cancer therapy.
DorchesterAges 16 years+ - NCT07011316Recruiting
Preventing lymphedema in cancer patients through monitoring
This trial tests whether a simple standing test can help spot early signs of lymphedema (swelling) in cancer patients. If you are being treated at the Greater Poland Cancer Centre, you may be able to help doctors learn how to prevent this side effect.
Poznan, Greater Poland VoivodeshipAges 18 years+ - NCT06967662Enrolling by invitation
Plasma Adsorption to Prevent Pancreatic Cancer Spread During Surgery

Moscow, Moscow OblastAges 18–75 - NCT06421285Recruiting
Exercise before breast cancer surgery to prevent lymphedema
This trial tests whether doing exercise before surgery can help prevent arm swelling (lymphedema) in women being treated for breast cancer. If you are newly diagnosed, facing chemotherapy first, and can exercise safely, this study might be a good fit.

Common questions
- Are there clinical trials for cancer prevention?
- Yes. Clin2 currently lists 290 recruiting cancer prevention studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a cancer prevention trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a cancer prevention trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
