It's important to remember that other, benign conditions may have caused these changes. For example, changes to the skin texture on the breast may be caused by a skin condition like eczema, and swollen lymph nodes may be caused by an infection in the breast or another, unrelated illness. Seeing a doctor for an evaluation will help you determine whether something you notice is cause for concern.
Perhaps the most recognized symptom of breast cancer is a lump or mass in the breast tissue. While many women go to the doctor after finding a lump, every woman should also be aware of other changes to the breast or nipple.
With the different types of breast cancer come a variety of related symptoms. For example, invasive ductal carcinoma (IDC), which forms in the milk ducts, may cause a distinct breast lump that you can feel. Invasive lobular carcinoma (ILC), which forms in milk-producing glands, may cause a thickening in the breast.
Symptoms of breast tumors vary from person to person. Some common, early warning signs of breast cancer include:
Skin changes, such as swelling, redness, or other visible differences in one or both breasts
An increase in size or change in shape of the breast(s)
Changes in the appearance of one or both nipples
Nipple discharge other than breast milk
General pain in/on any part of the breast
Lumps or nodes felt on or inside of the breast
Symptoms more specific to invasive breast cancer are:
Irritated or itchy breasts
Change in breast color
Increase in breast size or shape (over a short period of time)
Changes in touch (may feel hard, tender or warm)
Peeling or flaking of the nipple skin
A breast lump or thickening
Redness or pitting of the breast skin (like the skin of an orange)
