Breast cancer is something most of us feel we “know about”, we’ve seen the campaigns, heard the advice, and understand the importance of checking ourselves. But when you actually stop and think about it, are we completely clear on the details?
In this conversation, consultant oncoplastic and reconstructive breast surgeon Mr Jamie Vatish shares clear, practical guidance on how we can reduce our risk of breast cancer, what really matters when it comes to lifestyle, and how to stay aware without becoming anxious. It’s a reassuring and honest discussion.
In this episode, Mr Jamie Vatish talks through the key factors that influence breast cancer risk, including lifestyle, weight, alcohol, and hormone replacement therapy (HRT). He also explains how screening works in the UK, what to look for when checking your breasts, and why early detection makes such a difference.
This is a really helpful listen for anyone wanting a clearer, more grounded understanding of breast cancer, without the confusion or mixed messaging.
Top 5 highlights from the conversation
1. Around one in three breast cancer cases could be preventable
One of the most striking points from this discussion is just how much lifestyle matters.
In the UK, it’s estimated that around 30% of breast cancer cases could be prevented through improvements in overall health. The biggest drivers are being overweight, alcohol consumption, and smoking.
What often surprises people is that weight has such a strong link. We tend to associate it with conditions like diabetes or heart disease, but it also has a clear impact on breast cancer risk.
2. Weight plays a particularly important role, especially after menopause
Mr Vatish explains that body fat becomes more significant after menopause because fat tissue produces oestrogen. Many breast cancers are driven by oestrogen, so higher levels can increase risk.
To put it into perspective, the general risk of breast cancer in the UK is around 1 in 7 women. For women with a BMI over 30, that risk increases to around 1 in 5.
That doesn’t mean risk only starts later in life; being overweight before menopause still increases risk, but it becomes more influential afterwards.
3. HRT is generally safe but it’s not risk-free
There has been a lot of confusion around hormone replacement therapy over the years, and it’s easy to see why.
Mr Vatish explains that while earlier studies overstated the risks, it’s also not accurate to say HRT carries no risk at all. Because HRT contains oestrogen, it can slightly increase breast cancer risk.
What matters most is:
- The type of HRT (oestrogen-only vs combined)
- How long it’s taken for
Combined HRT (oestrogen and progesterone) taken for less than five years carries a low risk. However, longer use, particularly for around ten years, can significantly increase the risk.
It comes down to balancing benefits and risks. For many women, HRT can make a huge difference to quality of life, but it’s important to make informed choices.
4. Screening and self-checking are essential and often underused
Breast screening in the UK begins from age 50, with invitations every three years. However, your first invite may not arrive until around age 52.
Screening stops automatically at 70, but you can continue if you request it.
Alongside screening, self-examination plays a really important role. It doesn’t need to be complicated; once a month is enough.
The key is simply noticing change:
- A new lump
- A difference between one breast and the other
- Changes in shape or size
- Skin changes or redness
- Nipple changes or discharge
Many people assume breast cancer always presents as a lump, but that’s not always the case. And while most changes won’t be cancer, they should still be checked.
5. Early detection makes a huge difference to outcomes
One of the most reassuring parts of this conversation is just how treatable breast cancer can be when caught early.
Stage 1 breast cancer has a 5-year survival rate of around 99%. Treatments are also becoming more targeted and, in many cases, more manageable.
Early-stage treatment often involves:
- Surgery
- Radiotherapy
- Hormone therapy
Chemotherapy is not always needed.
At the same time, more women are being diagnosed each year, and lifestyle is part of that picture. So while treatment continues to improve, prevention and early detection remain just as important.
Understanding Breast Cancer: The Basics
Breast cancer is one of the most common cancers in the UK, particularly in women over 40, with risk increasing with age.
While it can feel overwhelming, there are some clear things we can focus on:
- Maintaining a healthy weight
- Limiting alcohol
- Staying physically active
- Being aware of family history
- Attending screening appointments
- Checking your breasts regularly
There isn’t one single cause of breast cancer. It’s usually a combination of factors over time. The aim isn’t perfection it’s awareness and small, consistent choices.
