Breast Lump | Lump in Breast
At MaineHealth, our healthcare providers offer comprehensive breast care services that include evaluation, imaging and diagnosis of breast changes, breast lumps and breast tumors.
What is a breast lump?
A breast lump is a mass of tissue that forms in the breast. Not all breast lumps are the same. Breast lumps can look and feel different, depending on the type of breast lump. Most breast lumps are not cancer. Sometimes breast lumps can be a symptom of breast cancer.
The following are breast conditions that can cause breast lumps:
- Breast cancer
- Breast cysts: Fluid-filled sacs that usually are not cancer;
- Fibroadenoma: Solid mass that is benign (noncancerous);
- Fibrocystic breasts: lumpy breast tissue;
- Intraductal papilloma: Wart- or pimple-like growth;
- Lipoma: Slow-growing mass that is not cancerous;
- Mastitis: Breast infection that affects women who are breastfeeding;
- Milk cyst (galactocele): Milk-filled cyst.
Latest mammogram technology
MaineHealth has the most advanced mammogram services at specialty clinics, breast care clinics and community hospitals, making it convenient to have routine and diagnostic breast exams.
Here are signs and symptoms that should be seen by a doctor:
- Breast lump is firm and stays in place
- Breast lump does not go away after four weeks to six weeks
- There are skin changes on your breast, including redness, crusting, dimples, puckering
- You have discharge, such as blood, from your nipple
- There are lumps under your arms, and they seem to be getting worse.
- Diagnosing a breast lump and breast change
The following screenings are used to diagnose breast lumps:
- Diagnostic mammogram: More X-rays are taken of the breast than for a routine screening mammogram.
- Breast ultrasound: Looks for breast changes that may not be picked up on a mammogram.
- Magnetic resonance imaging (MRI): Looks for breast cancer in women known to be at high risk. Also used to take a closer look at breast cancer, after it is found.
- Ductogram: Shows the cause of nipple discharge, using dye and an X-ray.
Screenings will show a suspicious area, but biopsies can tell whether it's cancer. A biopsy removes cells that are then looked at under a microscope.
