What Amy Robach's On-Air Mammogram Can Help Us Understand About Breast Cancer

Her account, in her own words

Writing for ABC News a year later, Amy Robach described agreeing to have a mammogram live on Good Morning America on October 1, 2013. She was 40. She had put off her first mammogram because she was busy, because she expected it to hurt, and, as she put it, because she was not worried about actually having breast cancer. She had no family history.

A few weeks later a follow-up appointment with an ultrasound and a biopsy showed a malignant mass in her right breast. After surgery in November 2013 her surgeon found a second malignant tumor and determined that the cancer had reached her sentinel lymph node. She has written that her treatment included two surgeries, breast expanders for seven months, and eight rounds of chemotherapy. ABC News reported in 2015 that she had a double mastectomy.

That is her public account. This page does not add to it or describe her health now. The rest is about the test.

What a mammogram is looking for

A mammogram is an x-ray of the breast. NCI explains that mammograms are used for screening because they can find tumors at an earlier stage, before they cause symptoms. That is exactly the situation Robach described: she felt fine when the pictures were taken.

NCI lists three things the images show.

A mass, meaning a lump. Its size, shape, and edges matter. A lump that is smooth and round with clear edges is often a benign cyst. A jagged outline or an irregular shape prompts more tests.

Calcifications, meaning deposits of calcium too small to feel. NCI is clear these have nothing to do with calcium in your diet. Macrocalcifications look like small white dots and usually come from aging, an old injury, or inflammation. Microcalcifications look like white specks, and when they are clustered in a certain way they can signal ductal carcinoma in situ or invasive cancer.

Breast density, meaning how much of the breast is dense tissue rather than fat. NCI notes plainly that mammography is more likely to miss cancer in women with dense breasts.

Reading the report

Screening results arrive within about two weeks and carry a BI-RADS category. NCI sets them out:

• 0 — more imaging needed before a category can be given
• 1 — negative; carry on with regular screening
• 2 — a benign finding; carry on with regular screening
• 3 — probably benign; a repeat mammogram in six months
• 4 — suspicious; may need a biopsy
• 5 — highly suggestive of cancer; needs a biopsy
• 6 — cancer already proven by biopsy

A category 0 is a callback, not a result. NCI's own wording is worth keeping: most people called back for further testing are not found to have breast cancer. Our page on what happens after an abnormal mammogram walks through the next steps.

The sentinel node

Robach's account mentions a sentinel lymph node. NCI defines it as the first node cancer cells are most likely to reach from a primary tumor. There can be more than one.

To find it, a surgeon injects a radioactive tracer, a blue dye, or both near the tumor, then uses a detector to see which node takes it up. That node is removed and examined. A negative result suggests the cancer has not spread to nearby nodes. A positive one means it has reached that node and may have gone further, and it changes both the stage and the treatment plan. Our page on sentinel lymph node biopsy explains the procedure in more detail.

When screening should start

The US Preventive Services Task Force recommends a screening mammogram every two years for women aged 40 to 74. It moved the starting age down to 40 in 2024. For women 75 and older, and for extra ultrasound or MRI in women with dense breasts, the Task Force says the evidence is not enough to judge.

Some people start earlier. NCI gives two examples: anyone treated for a childhood cancer with radiation to the chest may be advised to start at 25, or eight years after finishing radiation, whichever is later. People with a harmful BRCA1 or BRCA2 change may also screen earlier or more often.

The numbers

American Cancer Society projections for 2026 come to 321,910 new US cases of female breast cancer and 42,140 deaths. Five-year relative survival across all stages, for cases diagnosed in 2016 through 2022, is 91.9%.

By stage: localized 100.0%, regional 87.5%, distant 33.8%. About 64% are found while still localized and 27% at the regional stage, which is the group that includes a positive node.

These are group figures from large numbers of people treated in past years. They do not describe any one person.

When to get checked

Book a screening mammogram if you are 40 to 74 and have not had one in two years. Between screenings, NCI lists these changes as reasons to check with a doctor, without waiting for the next appointment:

• A lump in or near the breast, a lump under the arm, or a thick or firm area in either place
• A change in the size or shape of a breast
• Dimples or puckering of the skin, or swelling with no lump
• Skin that is scaly, swollen, red, or darker than usual on the breast, nipple, or areola
• A nipple that flattens or changes the direction it points
• Fluid or discharge from the nipple that is not breast milk

NCI adds that breast cancer does not usually cause pain, and that most breast changes are not cancer. Our guide to mammograms covers the practical side, including the discomfort.

What this does not mean

• One televised diagnosis is a story, not evidence. Screening schedules come from trials across large populations.
• A normal mammogram does not rule out cancer, particularly in dense breasts. A new lump still needs checking.
• A callback is not a diagnosis. Most people recalled do not have cancer.
• The survival figures above are group averages from past years and do not predict any individual result.
