Nipple discharge
There are various types of nipple discharge, and most of them are not associated with cancer. However, it is another symptom you should take into consideration, and you will need to ask your doctor to perform lab tests and imaging tests in order to track down the cause.
Nipple discharge in breast cancer can be of a clear color, milky, yellowish or even greenish. It is often a foul-smelling discharge, and it is associated with other symptoms such as the appearance of a lump in the breast and inflammatory changes.
In every case, you would need to get checked up if you’re not breastfeeding and start having a nipple discharge. It happens to some women during their menstrual cycle, but in other cases, it is a signal of breast infections, hormonal imbalances, a side effect of certain medications or breast cancer.
