It is important to let your cancer doctor or nurse know about any symptoms or side effects that do not improve. If you notice anything unusual between appointments, contact your cancer doctor or breast care nurse straight away.
Your breast care nurse can tell you what to expect after treatment. They can explain what to look for in the treated breast, your chest area (if you had a mastectomy) and in the lymph nodes close to the breast.
It is also important to know what to look out for in your untreated breast. We have more information about the signs and symptoms of breast cancer to help you.
Breast cancer that comes back in another part of the body is called secondary breast cancer. We also have information about possible symptoms of secondary breast cancer.
Breast cancer that comes back in the treated breast, chest or scar is called a local recurrence. Having a local recurrence does not mean the cancer has spread.
Breast cancer that comes back in the lymph nodes in the armpit, close to the breast bone, or lower neck, is called a regional recurrence. If cancer cells are blocking the lymph nodes in the armpit, fluid can build up in the arm and cause lymphoedema.
To diagnose a local or regional recurrence you have some of the same tests you had to diagnose primary breast cancer.
Your doctor may also recommend further tests to check that the cancer cells have not spread to other parts of the body.
Your treatment will depend on the treatment you have already had for breast cancer. Your doctor and nurse will talk to you about the most effective treatment for you.
Treatments for local or regional recurrence may include:
If tests show the cancer has spread to other parts of the body, such as the bones or lungs, this is called secondary breast cancer.
Learning you have secondary breast cancer may be harder than dealing with the first diagnosis. There are different treatments for secondary breast cancer that may help to control it for many years. We have more information about secondary breast cancer.
