Lifestyle affects risk of breast cancer in women 生活方式影響女性患乳腺癌的風險

Sunday 05/23/2021 (jkzx.com) — A study conducted by Ji Hyun Kim et al. from the National Cancer Center in Korea and published in 2017 in Nutrients suggests that a woman’s lifestyle can influence her risk of breast cancer.

The study was based on data from a cohort of women aged 30 years or older who were recruited between August 2002 and May 2007 and followed until December 2014. During the follow-up of 5046 participants initially without breast cancer, 72 ended up being diagnosed with breast cancer.

The study found specifically:

1) Women receiving college or higher education were 45% more likely to develop breast cancer than those with less education. This is due likely to the fact that highly educated women tend to marry at an older age, are more likely to have a child late, have more stress from their work, and spend less time taking care of their health.

2) Smoking seems to increase risk of breast cancer. The risk of smoking-related breast cancer was more than doubled, compared to those who did not smoke. It has been clear that smoking increases all sorts of cancer.

3) Eating grilled meat raised the risk of breast cancer drastically. The overall increase in the risk among all women was 77%. The risk was particularly significant in postmenopausal women, three times as high as that for women who rarely ate grilled meat. Grilled meat or overly cooked meat contain carcinogen. Red meat contains heme iron which promotes liquid oxidation. All of these promote cancer development.

4) Similarly, eating high cholesterol foods was associated with 69% increased risk of breast cancer in all women. Cholesterol is positively related with sex hormone which has been known to promote breast cancer.

5) Irregular meal intake also increased risk of breast cancer by as high as 110% in all women and in premenopausal women, the risk increase was even higher. Irregular meal intake could mean that eating less quality meal and at bad time. For instance, eating dinner too late or at late night can be a risk factor for breast cancer.
