Symptoms
By Mayo Clinic staff
Signs and symptoms of breast cancer may include:
- A breast lump or thickening that feels different from the surrounding tissue
- Bloody discharge from the nipple
- Change in the size or shape of a breast
- Changes to the skin over the breast, such as dimpling
- Inverted nipple
- Peeling, scaling or flaking of the nipple or breast skin
- Redness or pitting of the skin over your breast, like the skin of an orange
When to see a doctor
Although the majority of breast changes don't turn out to be cancer, make an appointment to see your doctor if you find a lump or other change in your breast. Even if you've just had a mammogram with normal results, it's still important to have your doctor evaluate any changes.
