Breastfeeding is widely recognized as the best source of nutrition for newborns, offering countless health benefits. But a recent study has raised an unexpected question—could being breastfed be linked to a higher risk of colorectal cancer later in life?
Researchers from Dana-Farber Cancer Institute analyzed health data from over 150,000 women and found that those who were breastfed had a 23% increased risk of developing colorectal cancer as adults. For those breastfed for nine months or longer, the risk doubled.
Does this mean breastfeeding is unsafe? Absolutely not. Experts still strongly recommend breastfeeding as the best option for infant nutrition. The study doesn’t prove that breastfeeding causes colorectal cancer—it simply highlights a potential connection that needs further research.
One possible explanation is the influence of breast milk on the gut microbiome, a key factor in long-term health. Other environmental and dietary factors may also play a role.
What does this mean for young adults? While more research is needed, one key takeaway is early cancer screening matters. Colorectal cancer rates are rising in younger people, so if you’re approaching 40 or have a family history, talk to a doctor about screening earlier than the usual recommendation at age 50.
Science is always evolving, and this study is just the beginning. Stay informed, prioritize preventive care, and make health choices based on the best available evidence.
