How Does Coffee Affect Breast Health? – Triwi Global!

how does coffee affect breast health

In today's world of complex issues and ticking timers, many of us like to boost ourselves with a lovely cup of coffee or two almost every day. Be it in the office, at your lunch break, or even in the morning to get you up and running, we really don't shy away from our ol' buddy Joe.



And not for nothing either, because caffeine has numerous benefits for your health and productivity, when consumed in moderation, of course. But does coffee affect breast health?


According to The American Cancer Society, The average risk of a woman in the United States developing breast cancer sometime in her life is about 13%. That means that one in eight women will have to battle breast cancer at some point.


And going up against such real chances of developing a severe form of cancer means that we all have to take good care of our health and avoid foods and behaviors that are risk factors, especially if that risk factor is something we consume on a daily basis.


As will be described later, current research is contested as to a correlation between caffeine and breast cancer. However, a significant majority points to no clear link between the two.

Does Caffeine Cause Breast Cancer?

Much of the argumentation on the harmful effects of caffeine on breast health is rooted in a controversial debate on coffee's impact on the possibility of developing fibrocystic breasts. This refers to the development of denser tissue within the breast that may feel a bit lumpy on the outside and can cause pain for many.


It has been falsely believed by many that fibrocystic breasts are caused by coffee and are signs of future cancers. Yet, it has now been made clear that this condition is completely ordinary and commonplace in women, occurring in roughly half of women between the ages of 20 and 50.


Furthermore, contrary to traditional beliefs, fibrocystic breasts are not harmful to your health or precursors of breast cancer.


The theory of a link between caffeine and fibrocystic breasts has affected many women negatively in the past, but it is now apparent through extensive experimentation that there is no clear correlation between the two.


A 2008 study sponsored by the U.S. Department of Health & Human Services looked at the rate of breast cancer development in 85.000 participants with varying levels of caffeine consumption. Each participant was monitored for 22 years to record possible breast cancer cases. However, the study failed to observe any correlation between coffee, tea, and breast cancer.


Here are the findings:

“The multivariate relative risks (RRs) of breast cancer across categories of caffeinated coffee consumption were: 1.0 for <1cup/mo (reference category), 1.01 (95% confidence interval: 0.92–1.12) for 1/mo-4.9/wk, 0.92 (0.84–1.01) for 5/wk-1.9/d, 0.93 (0.85–1.02) for 2–3.9/d, 0.92 (0.82–1.03) for ≥4 cups per day (p for trend= 0.14). Intakes of tea and decaffeinated coffee were also not significantly associated with risk of breast cancer.”.

Can Coffee Increase Breast Density?

What Is Breast Density?

Breast density refers to the amount of glandular and fibrous connective tissue within the breast compared to fat tissue.


On a mammogram, denser tissues are observed as whiter and more opaque than fat tissue, which is more transparent.



Breast density cannot be measured in a self-exam or clinical breast exam but requires a mammogram to be measured accurately.


Breast density is a risk factor for breast cancer. The reasons for this are unknown, but numerous studies have pointed to a concrete link between the two. However, the mortality rate of patients with dense breasts is not more than that of non-dense breasts.


Breast density is classified into one of the following four categories on a mammogram report:

  • A large portion of the breasts comprises fat (about 10 percent of women).

  • The br
