Stage 3 breast cancer means that the cancer has spread to 4 to 9 lymph nodes in the armpit. These tumors can be any size. At this stage, appropriate treatments are needed to minimize the spread to distant parts of the body.

Breast cancer is one of the 10 most common cancers in Vietnamese women. The age of breast cancer is tending to be younger, with some breast cancer patients in their teens, with the average age being around 30 years old.

Stage 3 breast cancer means the cancer has spread outside the main breast tumor. It may have invaded the lymph nodes but has not spread to nearby organs.

Breast cancer is a leading cause of death in women. Early detection of breast cancer in its early stages, such as stages 1 and 2, contributes to a good prognosis for treatment and long-term survival.

Stage 3 breast cancer is called advanced breast cancer, although it has not spread far, but treatment will be more difficult than early breast cancer. However, with advances in medicine, patients with stage 3 breast cancer can still be treated effectively and have a relatively high survival prognosis.
