Do You Check Your Underarms During a Breast Self-Examination?
A breast self examination should include more than the centre of the breast. The outer breast tissue and the underarm area matter too. During breast self-awareness, notice whether there is a new lump, thickening, swelling, skin change, nipple change or a persistent lump in the armpit. The underarm contains lymph nodes, and breast tissue extends toward this area. A change under the arm does not automatically mean breast cancer. Infections, skin irritation, recent vaccination, benign breast conditions and other causes can also make the area feel different. Still, a new or persistent change deserves a timely clinical review. Quick answer: Check the entire breast area from the collarbone to the lower breast and from the breastbone to the underarm. Use the finger pads of the opposite hand to gently feel the armpit and the outer breast. If you notice a new, persistent or growing lump, swelling or skin change, arrange an appointment with a breast doctor. Why Should You Check Your Underarms During Breast Self-Examination? Breast tissue is not limited to the rounded area visible on the chest. It extends outward toward the armpit. The underarm, also called the axilla, contains lymph nodes that help the immune system filter fluid and respond to infection. When breast cancer spreads beyond the breast, nearby axillary lymph nodes can be involved. However, underarm swelling has many non-cancer causes. A tender node may occur with a skin infection, a recent illness, shaving irritation or a vaccination. This is why a self-check is useful for noticing a change not for diagnosing its cause. In Nepal, breast cancer was the most commonly diagnosed cancer among females in GLOBOCAN’s 2022 estimates, with 2,255 new cases. That makes practical breast awareness, timely assessment and appropriate screening important parts of women’s health. A self-check cannot find every breast cancer. Some changes are too small to feel, and many cancers are first found on imaging. Think of breast self-awareness as a way to know what is normal for you and to speak up promptly about changes between routine appointments or mammograms.

Is Breast Self-Examination the Same as Breast Cancer Screening? No. A breast self-examination is a personal check for changes in the breasts and underarms. It is not a replacement for screening mammography, clinical assessment or diagnostic imaging. Many health organisations now emphasise breast self awareness rather than requiring everyone to perform a strict monthly examination. The goal is to understand your usual breast and underarm appearance and feel, then report a meaningful change without delay. Method Main purpose What it can and cannot do Breast self-awareness Helps you notice changes in your own body Can identify a new lump, swelling or skin/nipple change; cannot confirm cancer Clinical breast examination A trained clinician examines the breast and nodes May identify abnormalities that need imaging; does not replace appropriate screening Mammography or other screening Finds possible cancer before symptoms develop in eligible people Can detect some cancers too small to feel; needs an individual plan based on age and risk Diagnostic imaging and biopsy Investigates a concerning symptom or screening finding Helps establish the diagnosis and guide treatment Do not wait for a self check to replace scheduled screening. Discuss the right screening schedule with a breast doctor in Nepal, particularly if you have a strong family history, a previous high-risk breast condition, a genetic mutation, prior chest radiation or a personal history of breast cancer. What Can You Notice During a Breast and Underarm Self-Check? Breast self-awareness is about noticing a new or different change. It is not about deciding whether something is harmless or cancerous by touch. Change to notice Where it may appear What to do New lump, thickening or firm area Breast, outer breast or armpit Arrange a clinical examination Underarm swelling or a distinct node One armpit or near the upper outer breast Get reviewed if new, persistent, growing or unexplained Skin dimpling, puckering, thickening or redness Breast, nipple or underarm skin Seek prompt medical advice Change in nipple direction or shape Nipple/areola Discuss a new inversion or persistent change Clear or bloody nipple discharge not related to breastfeeding Nipple Arrange a medical review Change in breast size, shape or contour One or both breasts Get checked when it is new or progressive Persistent localised pain Breast or underarm Review if it does not settle or has no clear explanation Most lumps are not cancer. Cysts, fibroadenomas, hormonal changes, infection and enlarged lymph nodes are common examples of non-cancerous causes. But a new lump should be assessed rather than watched indefinitely.

The aim is to gently feel for a new, distinct or persistent change. You do not need to press hard, repeatedly squeeze the area or search for a diagnosis. A Simple Underarm Self-Check If you find a change, make a short note of the date, side, location and whether it is painful. Then arrange an appointment rather than repeatedly checking it every day. How to Check Breasts and Armpits for Lumps: A Practical Routine A structured check can help you cover the whole area. It is best done when you are calm and not rushed. People who menstruate may find the breasts less tender after their period; people without regular cycles can choose the same day of the month if they prefer a routine. Step 1: Look in the Mirror With your upper body uncovered, look at both breasts with arms relaxed at your sides. Then raise your arms and place your hands on your hips or press your palms together to tighten the chest muscles slightly. Look for a new change in shape, size, contour, skin texture, redness, dimpling, swelling, nipple position or rash. Include the upper chest and underarms. … Read more
