The majority of women with breast cancer do not have any signs or symptoms when diagnosed.
The signs and symptoms that should be discussed with a doctor are listed below. Many times, the cause of a symptom may be a different medical condition that is not cancer.
A lump that feels like a hard knot or a thickening in the breast or under the arm. It is important to feel the same area in the other breast to make sure the change is not a part of healthy breast tissue in that area.
Change in the size or shape of the breast
Nipple discharge that occurs suddenly, is bloody, or occurs in only 1 breast
Physical changes, such as a nipple turned inward or a sore in the nipple area
Skin irritation or changes, such as puckering, dimpling, scaliness, or new creases
Warm, red, swollen breasts with or without a rash with dimpling resembling the skin of an orange, called “peau d'orange”
Pain in the breast, particularly breast pain that does not go away. Pain is not usually a symptom of breast cancer, but it should be reported to a doctor.
If you are concerned about any changes you experience, please talk with your doctor. Your doctor will ask how long and how often you have been experiencing the symptom(s), in addition to other questions. This is to help figure out the cause of the problem, called a diagnosis.
If cancer is diagnosed, relieving symptoms is an important part of cancer care and treatment. This may be called palliative care or supportive care. It is often started soon after diagnosis and continued throughout treatment. Be sure to talk with your health care team about the symptoms you experience, including any new symptoms or a change in symptoms.
