Breast Cancer Screening

What is breast cancer screening?

Breast cancer screening means having regular checks — a clinical exam, mammography, and sometimes ultrasound — to look for early changes in breast tissue, often before anything can be felt as a lump or causes any symptom at all. Many breast cancers give no early warning signs, which is exactly why screening matters.

Why does early detection matter so much?

The numbers here are worth knowing. When breast cancer is caught early, the five-year survival rate can be as high as 99% (American Cancer Society). Large studies, including long-running research from Sweden and the United States, have found that regular breast screening can reduce the risk of dying from breast cancer by up to 40%. Screening doesn't prevent breast cancer — but it gives you the earliest possible chance to act on it, with the most options available.

Who should consider screening, and when?

For women at average risk, general guidance looks like this:

• Ages 40–44: you can choose to begin yearly mammograms if you wish to start early
• Ages 45–54: yearly mammograms are generally recommended
• Age 55 and older: continuing yearly, or moving to every two years, depending on your doctor's advice and your own preference

Screening may reasonably start earlier, or happen more often, if you:

• Have a family history of breast or ovarian cancer, especially in a mother, sister, or daughter
• Carry a known BRCA1 or BRCA2 gene mutation
• Received radiation therapy to the chest before age 30
• Have certain non-cancerous breast conditions or a strong personal health history

These are general guidelines, not a fixed rule — ask Dr. Chandak for a personal screening plan based on your own history.

What does screening involve?

• Clinical Breast Exam (CBE): a hands-on check by a doctor, recommended yearly from age 20 onward, often as part of a routine health check-up
• Mammography: the main screening tool, a low-dose X-ray that can detect changes before you can feel them
• Sono-mammography (breast ultrasound): often used alongside mammography, particularly for women with dense breast tissue, or sometimes recommended instead of a mammogram for women under 40
• Breast MRI: reserved for higher-risk women, such as those with a BRCA mutation or strong family history, when even more detailed imaging is needed
• Biopsy or FNAC: used if something found on screening needs a closer, tissue-level look

Self-breast exam: your first, free tool

A monthly self-check helps you learn what's normal for your own body, so you're more likely to notice a genuine change between screenings.

• Look: in front of a mirror, arms by your side and then raised overhead, checking for skin changes, swelling, or nipple changes
• Feel: using the pads of your fingers in circular motions, covering the entire breast and the underarm area — many find this easiest in the shower or lying down
• Repeat monthly: ideally a few days after your period ends, or on a fixed date each month if you're postmenopausal

If you notice a new lump, thickening, or any change, don't panic — but do get it checked. See our Breast Lump page for more.

Understanding your results

• Normal: no signs of concern were found; continue routine screening as recommended
• Unclear or unusual: this does not mean cancer — it means the images showed something that needs a closer look, often with a repeat or different type of scan
• Further testing recommended: helps determine whether a finding is benign (such as a cyst) or needs tissue sampling via FNAC or biopsy

Common myths about breast screening

• "I don't feel any lumps, so I don't need screening." Most cancers found through screening show no symptoms at all — that's the entire point of screening.
• "Mammograms are too painful." Most women describe brief pressure, not real pain, lasting only a few seconds per image.
• "An abnormal result means I have cancer." Not at all — most abnormal findings turn out to be benign once looked at more closely.
• "Screening is only for older women." It can start as early as 40, or earlier for higher-risk women.
• "A healthy lifestyle means I don't need screening." A healthy lifestyle supports overall wellbeing, but it doesn't remove the need for regular screening.
