Breast cancer self-checks: how to examine yourself at home

When people think of breast cancer awareness, one word usually comes to mind: a "lump". But doctors warn that this simplified picture can mislead people about what to actually look for. Actress Lucy Davis brought renewed attention to the issue by sharing her own experience — what she found wasn't a classic lump at all, but a small, hard spot beneath the skin.

Davis's account highlights just how varied breast tissue can feel. Breast tissue is naturally uneven: some areas feel denser, others softer, and texture can shift with the menstrual cycle. That's why specialists emphasise getting to know your own breasts over time, rather than relying on a single check to catch something significant.

The purpose of regular self-checks isn't to make a diagnosis — that's a doctor's job — but to learn what is normal for your own body, so that any change becomes noticeable. Breast cancer nurses generally recommend checking around once a month, ideally at the same point in the menstrual cycle each time, since hormonal shifts can temporarily change how tissue feels.

The check itself is simple. It starts with looking in a mirror for any visible change in the shape of the breast, the skin, or the nipple, followed by feeling both breasts and the armpit area with the pads of the fingers, using small circular motions, either in the shower or lying down. The goal isn't specifically to search for a hard lump — it's to notice anything that feels different from what's usual for you.

Specialists point to several signs worth paying attention to: a new lump or area of thickening, a change in the size or shape of the breast, dimpling or puckering of the skin, a nipple that turns inward, discharge from the nipple that is bloody or clear, and swelling in the armpit. Some of these changes can have causes unrelated to cancer, but doctors advise seeing a GP regardless, just to rule it out.

Early detection matters because it widens the range of treatment options available. Cancers caught at an earlier stage can often be treated less invasively, and survival rates are meaningfully higher. That's why health authorities encourage self-checks alongside routine screening programmes — self-checks are the most practical way to catch changes that develop in the gaps between scheduled screenings.

Public figures like Davis sharing personal, specific stories also helps address what doctors call "awareness fatigue" — the point at which people become so used to hearing campaign slogans that the message stops landing. A detailed personal account breaks through the generic mental image the word "lump" conjures, encouraging people to take seriously changes that feel different, even if they don't match that stereotype.

Doctors also note that men can develop breast cancer too, albeit far less commonly, and should watch for the same warning signs. Regardless of gender, anyone who notices an unusual change in the chest area is advised to see a health professional without delay.

Ultimately, a self-check at home cannot diagnose cancer, but it is a simple, free habit that helps someone become familiar with their own body and notice changes early. The consistent advice from specialists: don't just search for a lump — search for anything that feels different.
