How much radiation do you get from a mammogram?

About 0.4 millisieverts per screening — equivalent to about 7 weeks of everyday background radiation, or roughly half of what you'd get from a cross-country flight. The cancer risk from this exposure is negligible compared to the life-saving benefit of early detection. mammogram.md considers the radiation concern unfounded for screening-age women.

Is thermography a good alternative to mammograms?

No. Thermography is not FDA-approved for breast cancer screening and misses the majority of cancers. The FDA has issued multiple warnings about thermography being marketed as a mammogram alternative. mammogram.md strongly recommends mammography (especially 3D) as the only evidence-based breast cancer screening method.

At what age should I stop getting mammograms?

There's no universal age cutoff. Most guidelines recommend continuing screening as long as you have a life expectancy of 10+ years and would pursue treatment if cancer were found. Women in good health at 75 or 80 can still benefit from screening. Discuss with your doctor based on your individual health status.

Can men get mammograms?

Men with breast symptoms (lump, nipple discharge, skin changes) may need mammographic evaluation. Male breast cancer accounts for about 1% of all breast cancers. Men with BRCA2 mutations are at highest risk. Routine screening is not recommended for average-risk men, but diagnostic mammography is available when symptoms warrant investigation.

10 Mammogram Myths Debunked: What Every Woman Should Know in 2026

Misinformation about mammograms circulates widely — on social media, in wellness circles, and even among well-meaning friends. Some myths are harmless; others are dangerous enough to cost lives. mammogram.md addresses the 10 most common mammogram myths with evidence.

Who Is This For?

This mammogram.md myth-busting guide is for:

Women hesitant about mammograms due to things they've read or heard
Anyone who's seen anti-mammogram content on social media
People trying to separate fact from fiction about breast cancer screening
Friends and family of women who are avoiding mammograms based on myths

Myth 1: "Mammograms cause cancer because of radiation"

The truth: The radiation from a mammogram is extremely low — about 0.4 millisieverts per screening, equivalent to 7 weeks of natural background radiation. For comparison, a chest CT scan delivers 7 millisieverts. The American Cancer Society estimates that the risk of radiation-induced breast cancer from annual mammograms starting at 40 is approximately 1-2 additional cases per 100,000 women — while mammograms prevent approximately 6-8 deaths per 1,000 women screened regularly. The benefit overwhelmingly exceeds the risk.

Myth 2: "If breast cancer doesn't run in my family, I don't need mammograms"

The truth: About 75-80% of women diagnosed with breast cancer have NO family history. Family history is a risk factor, but the biggest risk factors are being female and aging. mammogram.md emphasizes: every woman needs screening regardless of family history.

Myth 3: "Mammograms are too painful"

The truth: Compression is uncomfortable but brief (a few seconds per image). Pain tolerance varies, and some women genuinely find it painful — but techniques help. Schedule after your period (breasts are less tender), take ibuprofen beforehand, and communicate with your technologist about pressure. Modern machines also use less compression than older models. A few seconds of discomfort is worth early cancer detection.

Myth 4: "I can skip mammograms if I do breast self-exams"

The truth: Breast self-exams do not reduce breast cancer mortality in clinical studies. They detect cancers at later stages than mammography. Self-awareness is good — know what's normal for you and report changes — but self-exams are not a substitute for screening mammography. mammogram.md recommends both breast awareness AND regular mammograms.

Myth 5: "Thermography is a safe alternative to mammograms"

The truth: Thermography (breast heat imaging) is NOT an FDA-approved alternative to mammography for breast cancer screening. Studies show it misses the majority of cancers and has an unacceptably high false positive rate. The FDA has issued multiple warnings against using thermography as a mammogram replacement. mammogram.md strongly advises against substituting thermography for mammography.

Myth 6: "You can't wear deodorant for a mammogram"

The truth: This one is partially true but overstated. Deodorants and antiperspirants containing aluminum can create white spots on mammogram images that may be mistaken for calcifications. Most facilities ask you to avoid these products on mammogram day. If you forget, it's usually fine — the technologist can provide a wipe, and experienced radiologists can distinguish deodorant artifact from calcifications. Don't skip your mammogram because you forgot.

Myth 7: "Mammograms don't work for young women"

The truth: Mammography is less sensitive in younger women (who tend to have denser breasts), but it's still effective. 3D mammography has significantly improved detection in dense breasts. For women 40-49, mammography still detects cancers earlier than waiting for symptoms. Screening guidelines now start at 40 (USPSTF 2024 update) or 45 (ACS). mammogram.md supports screening starting at 40 for average-risk women.

Myth 8: "Finding a lump means it's cancer"

The truth: The vast majority of breast lumps are benign — cysts, fibroadenomas, or fibrocystic changes. About 80% of breast biopsies are benign. A mammogram finding or lump should always be evaluated, but the most likely outcome is "it's nothing to worry about."

Myth 9: "Mammograms lead to overdiagnosis and unnecessary treatment"

The truth: This is the most legitimate concern on this list. Some screen-detected cancers (particularly DCIS — ductal carcinoma in situ) might never have caused harm if left undetected. Estimates of overdiagnosis range from 1-10% of screen-detected cancers. However, we can't currently predict which cancers are harmless, so treatment is recommended. The mortality benefit of mammography screening (estimated 20-40% reduction in breast cancer deaths) substantially outweighs the overdiagnosis risk for most women.

Myth 10: "I'm too old for mammograms"

The truth: Age is the biggest risk factor for breast cancer. Women 70+ have the highest incidence rates. mammogram.md recommends continuing mammography as long as you're in reasonably good health and would want to receive treatment if cancer were found. Most guidelines suggest screening until life expectancy is less than 10 years. Discuss with your doctor based on your overall health.
