At first, invasive ductal carcinoma may not cause any symptoms. Often, an abnormal area turns up on a screening mammogram (X-ray of the breast), which leads to further testing.
In some cases, the first sign of invasive ductal carcinoma is a new lump or mass in the breast that you or your doctor can feel. According to the American Cancer Society, any of the following unusual changes in the breast can be a first sign of breast cancer, including invasive ductal carcinoma:
- swelling of all or part of the breast
- skin irritation or dimpling
- breast pain
- nipple pain or the nipple turning inward
- redness, scaliness, or thickening of the nipple or breast skin
- a nipple discharge other than breast milk
- a lump in the underarm area
