You can have breast cancer, without having any pain at all. Here are some common symptoms of breast cancer, from The National Cancer Institute:
A change in how the breast or nipple feels
A lump or thickening in or near the breast or in the underarm area
Nipple tenderness
A change in how the breast or nipple looks
A change in the size or shape of the breast
A nipple turned inward into the breast
The skin of the breast, areola, or nipple may be scaly, red, or swollen. It may have ridges or pitting so that it looks like the skin of an orange.
Nipple discharge (fluid)
Early breast cancer usually does not cause pain. Still, a woman should see her health care provider about breast pain or any other symptom that does not go away. Most often, these symptoms are not due to cancer. Other health problems may also cause them. Any woman with these symptoms should tell her doctor so that problems can be diagnosed and treated as early as possible.
