Less invasive surgery for breast cancer after chemo

This trial studies a treatment plan for early breast cancer that involves at least three suspicious lymph nodes on the ultrasound/imaging. It looks at whether a targeted technique—done before surgery with chemotherapy—can improve or guide care when surgery will remove the lymph nodes.

This study looks at a less invasive way to check and treat lymph nodes in the armpit after you receive chemotherapy (and sometimes immunotherapy) before breast surgery. It may help people with cancer that has already spread to armpit lymph nodes by improving how staging and treatment are done.

This trial tests if it's safe to skip a sentinel lymph node biopsy (a procedure to check if cancer has spread to the lymph nodes under your arm) when the breast tumor has completely disappeared after chemotherapy. If the trial finds it's safe, you could avoid this extra surgery and its side effects.

This study looks at whether it's safe to do less extensive lymph node surgery (removing only the sentinel node instead of all lymph nodes) for breast cancer that has spread to lymph nodes, after chemotherapy has shrunk the cancer. The goal is to reduce side effects while still effectively treating the cancer.

This study checks whether some people with breast cancer who have no remaining cancer after medicine (neoadjuvant systemic therapy) can safely receive less radiation. It may help reduce side effects while still keeping cancer controlled.

This trial studies how doctors should operate on lymph nodes after you finish chemotherapy given before surgery. It may help improve treatment planning for people whose breast cancer has spread to nearby lymph nodes, but not to distant organs.
