What kind of doctor treats Breast Disorders?
A breast surgeon operates on breast problems and often manages breast disease overall. An OB/GYN specializes in women's reproductive health and breast care. Many people start with a primary care doctor, who can do an exam and order imaging. A radiologist reads imaging tests and may be involved when a biopsy is needed.
What it is
Breast disorders are problems that affect the breast tissue. Some are harmless, like fluid-filled sacs called cysts. Others, such as breast cancer, are serious. Most breast changes are not cancer, but every change deserves a check by a doctor.
Symptoms
Common signs include a lump in the breast or under the arm. The skin may look red, dimpled, or puckered. Nipples can leak fluid, turn inward, or feel sore. Pain alone is often not a sign of cancer, but it should still be mentioned to a doctor.
Causes and who gets it
Breast disorders have many causes. Hormone changes during the monthly cycle can cause lumps and tenderness. Infections during breastfeeding are called mastitis. Growths such as cysts or fibroadenomas are common and usually not cancer. The risk of breast cancer rises with age, with a strong family history, and with certain inherited gene changes such as BRCA. Being female, long exposure to estrogen, and being overweight after menopause also raise the risk.
How doctors diagnose it
The doctor will start with a physical exam and ask about symptoms and family history. Imaging tests are often next. A mammogram is an X-ray picture of the breast. An ultrasound shows whether a lump is solid or filled with fluid. If needed, a biopsy removes a small piece of tissue to check under a microscope.
Treatment
Treatment depends on the cause. Simple cysts may go away on their own or be drained with a needle. Infections are treated with antibiotics. Noncancerous growths may only need regular checkups. Breast cancer treatment can include surgery, radiation, chemotherapy, and hormone therapy. The plan depends on the type and stage of the problem.
When to see a doctor
See a doctor if you find a new lump or notice a change in your breast. Skin dimpling, nipple discharge, or a nipple that turns inward are also reasons to call. Redness, warmth, and fever can mean an infection that needs prompt treatment. Any change lasting more than a few weeks should be checked.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is one you pay with a flat monthly fee instead of using insurance for visits. A concierge doctor works in a similar way but usually costs more and often works alongside insurance. These doctors can examine breast symptoms, order mammograms and ultrasounds, and treat simple problems such as cysts or infections. If something needs surgery or cancer care, they will refer you to a specialist and coordinate follow-up care.
Common questions
Are most breast lumps cancer?
No. Most breast lumps are not cancer. Many are cysts, fibroadenomas, or normal tissue that changes with hormones. Any new lump should still be examined by a doctor.
Do breast disorders only affect women?
No. Men can get breast problems too, including breast cancer, though it is much less common. Men who notice a lump or nipple change should see a doctor.
When should I start getting mammograms?
Many expert groups suggest starting regular mammograms between ages 40 and 50, depending on your risk. People with a strong family history may need to start earlier. Talk with your doctor about the right timing for you.
