A recent US study warns that eating a lot of fatty food during adolescence might lead to higher breast density in early adulthood – indicating a higher risk cause for breast cancer.

“Overall, our results suggest possible long-term effects of fat intake during teenage years on young adult breast composition,” said Seungyoun Jung – one of the researchers from the University Of Maryland School Of Medicine in the US.



“Proper dietary modifications during teenage may possibly contribute to lowering breast density & consequently breast cancer risk as well as preventing diabetes, obesity & cardiovascular disease.” Jung added.

The study was published in the journal Cancer Epidemiology, bio-markers and Prevention.

  • Because breast tissue is one of the most subtle/delicate to different exposures in the teenage years, when breasts are in developing stage.
  • The team looked into a possible connection between fat consumption during this stage & breast density in early adulthood.


The team studied data from DISC – Dietary Intervention Study in Children. DISC was a multi center randomized trial started in 1988.

It enrolled 663 pre-adolescent children including 301 girls between the ages 8 – 10 years.  Who had assessed diet on several occasions during adolescence.

A follow-up study was conducted when partakers were 25 to 29 years old. Measured the breast density by magnetic resonance imaging in 177 female participants.

Researchers found out that a higher intake of saturated fat & lower intakes of mono- and polyunsaturated fat during adolescence, both were associated with a higher percent dense breast volume (DBV) in early adulthood.

Parallel differences were found for individuals in the lowest vs. the highest quartile of mono-unsaturated fat intake.

  • Food containing high amounts of saturated fats are usually found in fatty meats.
  • Dairy products like cheese, fatty meats, butter, olive oil, avocado and white nuts are among common sources of mono-unsaturated fats.
