Some lumps are small fluid-filled sacs called cysts or non-cancerous changes in the fibrous tissue of the breast. Your doctor can order tests to determine whether a lump could be cancerous.
quicklist: 2 category: Breast Cancer Signs title: Changes in Breast Size or Shape url: text: Breast cancer can change the way your breasts look and feel, but so can age, your menstrual cycle, pregnancy, breastfeeding, weight changes and some medications. Your doctor can tell you whether any changes you notice could be cancerous and order tests to follow up.
quicklist: 3 category: Breast Cancer Signs title: Breast Swelling or Redness url: text: Not all breast cancers cause lumps. Inflammatory breast cancer can look more like an infection. Although it's very rare, inflammatory breast cancer is aggressive, so it's important to get any redness or swelling checked out right away.
quicklist: 4 category: Breast Cancer Signs title: Skin Flaking or Dimpling url: text: Inflammatory breast cancer can also cause changes in the skin of the breast, sometimes making it look like orange peel. The swelling stems from blocked lymphatic vessels in the skin, though the cancer usually starts in the lining of the milk ducts. Your doctor can determine whether changes to your skin could be signaling cancer.

Talk to your doctor if your nipple turns inward or if you notice a discharge other than milk. In most cases, nipple changes do not signal cancer. But simple tests can help determine the cause.
