New data shows millions of men are searching for answers about chest changes, but many still don’t know the difference between normal tissue, gynaecomastia and the warning signs of breast cancer.
NATION WIDE – Searches for “man boobs” remain consistently high, with approximately 307,000 searches in the past month, according to analysis by men’s health platform Feel30. Meanwhile, searches for “male breast cancer” have surged by 131% over the past year, suggesting more men are becoming aware that breast cancer isn’t exclusively a women’s disease.
Health experts say the two topics are often confused, leading some men to ignore symptoms out of embarrassment, while others worry unnecessarily about harmless changes.
Anneliese Cadena, AGNP-C and Clinical Advisor at Feel30, says understanding what’s normal and what’s not is key.
“Many men notice changes in their chest at some point in their lives. In most cases, these changes aren’t cancer, but that doesn’t mean they should automatically be ignored.
One of the most common causes is gynaecomastia, which is the growth of normal breast tissue in men. It can happen during puberty, later in life, with weight gain, certain medications or hormonal changes. It’s incredibly common and often harmless.”
What Causes ‘Man Boobs’?
According to Anneliese Cadena, AGNP-C and Clinical Advisor at Feel30,, enlarged male breasts generally fall into one of two categories.
Gynaecomastia
An increase in actual breast tissue caused by hormonal imbalance, ageing, puberty, some medications or certain medical conditions.
Pseudogynaecomastia
A build-up of fat around the chest, often linked with being overweight or obesity.
“The important distinction is that gynaecomastia is breast tissue, whereas pseudogynaecomastia is excess fat. Weight loss may improve pseudogynaecomastia, but it won’t necessarily resolve true gynaecomastia because glandular tissue behaves differently.”
Can You Prevent It?
While not every case can be prevented, experts say several lifestyle factors may reduce the risk.
These include:
- Maintaining a healthy body weight
- Regular resistance and cardiovascular exercise
- Limiting excessive alcohol intake
- Avoiding anabolic steroids
- Speaking to a healthcare professional if medications appear to be causing breast enlargement
- Managing underlying health conditions that affect hormone levels
“Hormones naturally change throughout life, so prevention isn’t always possible. However, maintaining a healthy weight and looking after your overall metabolic health can significantly reduce many of the common causes.”
Does Having ‘Man Boobs’ Mean You Have Breast Cancer?
The short answer is no.
Male breast cancer remains rare, accounting for around 1% of all breast cancer diagnoses, and most men with enlarged breasts do not have cancer.
However, Anneliese says new or unusual changes should never be dismissed without assessment.
“Gynaecomastia itself doesn’t automatically mean someone has breast cancer. They’re two very different conditions.
The problem is that men sometimes assume every lump is harmless because they’ve heard of ‘man boobs’, while others panic that any chest change means cancer. Neither assumption is helpful. The safest approach is to have anything new, persistent or unusual assessed.”
When Should Men Get Checked?
Experts recommend seeing a healthcare professional if you notice:
- A new lump, particularly if it’s firm or only affects one side
- Nipple discharge, especially if blood-stained
- Changes to the nipple, including inversion
- Skin dimpling or puckering
- Persistent swelling that doesn’t improve
- Swollen lymph nodes under the arm
- Ongoing pain in one specific area of the breast or chest
“Most breast changes in men will turn out to be benign, but early assessment matters. Breast cancer in men is often diagnosed later simply because people don’t expect it to happen. If something feels different from what’s normal for you, it’s worth getting it checked.”
Breaking The Stigma Around Men’s Health
Anneliese Cadena, AGNP-C and Clinical Advisor at Feel30, believes the increasing search interest reflects a positive shift in how men approach their health.
“For years, many men avoided conversations about breast health because they felt embarrassed or assumed it wasn’t relevant to them.
Seeing more people actively searching for information is encouraging. Awareness leads to earlier conversations, earlier assessment and, when necessary, earlier treatment. That’s always a positive step.”
