## Quick answer

- Tender, lumpy breasts before your period are common.
- Get to know your normal with regular look-and-feel checks. A rigid routine is not needed.
- See a GP for any new lump or change that is not normal for you.
- NHS breast screening starts from 50.

Breasts change through your cycle. Many people notice they feel heavier, lumpier or more tender in the days before a period. That is called [Cyclical breast pain](https://splash.care/learn/glossary#cyclical-breast-pain), and it is very common.

## Cyclical breast pain

The NHS says breast pain linked to periods usually begins up to 2 weeks before a period, gets worse and then goes away when the period ends. It tends to feel dull, heavy or aching, affects both breasts, and can spread to the armpit.

- Take paracetamol or ibuprofen, or rub on a painkilling gel, if suitable for you.
- Wear a properly fitted bra in the day and a soft bra to [sleep](https://splash.care/learn/movement-sleep/sleep-cycle) in.
- The NHS notes there is little evidence that vitamin E tablets or evening primrose oil help.
- Some medicines, such as the pill and some antidepressants, can also cause breast pain.

## How to check your breasts

There is no special technique. The aim is to know what is normal for you, so you notice changes. A Cochrane review found that formal, scheduled breast self-examination did not reduce deaths from breast cancer and led to more unnecessary biopsies, which is why UK advice focuses on knowing your normal ("breast awareness") rather than a rigid routine. If checking at the same point in your cycle helps you remember, a few days after a period ends is a good time because breasts are usually less tender and lumpy.

1. **Look** in the mirror with arms down, then raised. Notice shape, skin and nipples.
2. **Feel** the whole breast, up to your collarbone and into your armpit, with the flat of your fingers.
3. **Check** for anything new or different, and [see a GP](https://splash.care/learn/conditions/talk-to-your-doctor) if you find something. Keep checking after [menopause](https://splash.care/learn/glossary/menopause) too.

This applies to trans and non-binary people too. If you have breast or chest tissue, get to know it. If you have had top surgery you may still have some tissue, so talk to a GP about anything that changes.

## Breast screening

NHS breast screening (mammograms) in England is offered from age 50 up to your 71st birthday. You will usually get your first invitation between 50 and 53, then every 3 years. Do not wait for screening if you notice a change.

### When to see a doctor

See a GP if you notice a lump or swelling in your breast, chest or armpit; a change in size or shape; dimpled skin (like orange peel); a change in skin colour; nipple discharge (especially with blood) when not pregnant or breastfeeding; or a nipple that has turned inward or has a rash. Ask for an urgent appointment or call NHS 111 if you have a hard lump that does not move, bloody nipple discharge, or any part of your breast is red, hot or swollen, especially with a very high temperature. Most changes are not cancer, but checking early matters.

> **Splash says:** set a "boob check" reminder that suits you. Two minutes in the shower is all it takes.

**Myth:** Breast pain is usually a sign of cancer.

**Fact:** The NHS says breast pain by itself is unlikely to be a symptom of breast cancer. Cyclical pain is very common. But a new lump or skin or nipple change always deserves a check.
