Most nipple discharges are not cancer. However, a cancer may be present if the nipple discharge:
- Comes out without squeezing the nipple or expressing the discharge.
- Comes from a single duct in one nipple.
- Tests positive for blood.
- Is in a woman who is over 60 and the discharge is new.
If any of these signs
are present, the doctor will recommend imaging tests and refer the
woman to a surgeon, usually with her test results.
If the discharge does not have any of these characteristics, no
further tests are necessary. However, the woman should return to
her doctor in two to three months if the discharge continues as
further tests may be required.
Nipple inversion
Nipple inversion is when the nipple grows inwards instead of out. If the nipple inversion is a new change, the doctor will examine the woman’s breasts to determine whether she requires more tests.
A cancer may be present if the nipple inversion:
- Looks like it is all pulled in together, rather than forming a slit shape.
- Cannot be pulled out to a normal shape.
- Has any scaliness, change in colour or ulcers.
- If a lump can be felt behind the nipple.
