HER2 Positive Breast Cancer Symptoms

A doctor listens to a patient describe her symptoms

The symptoms of HER2 (human epidural growth factor receptor 2) positive breast cancer are much like the symptoms of other breast malignancies. Most individuals with this form of cancer first notice a hard lump in a breast. Many breast lumps – the majority, in fact – are not cancerous, but it is still important to promptly speak with a physician if you notice a lump in one of your breasts.

What are some other signs of HER2 positive breast cancer?

In addition to a breast lump, other signs of HER2 positive breast cancer include:  

  • Unusual breast swelling or tenderness
  • Discomfort in a breast or nipple
  • Redness or a thickening in a breast or nipple
  • Unusual nipple discharge
  • Breast skin that appears irritated or dimpled

About 20 percent of all breast cancers are HER2 positive. Still, every patient is different, and some HER2 positive breast cancer symptoms are not as obvious as others. As a general rule of thumb, you should consult with a physician if you spot any breast abnormalities. A physician will be able to determine the root cause of your symptoms and recommend an appropriate course of treatment, if necessary.
