Diet and breast cancer: a case-control study in Greece

Area of Science:

• Epidemiology
• Nutritional Science
• Oncology

Background:

• Dietary patterns vary significantly across populations, influencing disease etiology.
• Breast cancer etiology is multifactorial, with diet playing a potential role.
• Previous studies suggest a link between diet and breast cancer, but population-specific data is crucial.

Purpose of the Study:

• To investigate the association between diet and breast cancer risk in Athens, Greece.
• To explore the role of specific food groups, including vegetables, in breast cancer etiology.
• To account for dietary heterogeneity within the Greek population.

Main Methods:

• A case-control study involving 120 breast cancer patients and 120 controls.
• Dietary histories were collected through interviews assessing consumption of 120 foods and drinks.
• Statistical analysis, including adjustment for confounding variables, was performed.

Main Results:

• Cases reported significantly lower consumption of vegetables as a group.
• Reduced consumption of cucumber, lettuce, and raw carrots was specifically noted in cases.
• The highest quintile of vegetable consumers had approximately 10 times lower breast cancer risk compared to the lowest quintile (OR=0.09).

Conclusions:

• Increased vegetable intake is associated with a reduced risk of breast cancer.
• Specific salad vegetables may play a protective role.
• Dietary interventions focusing on vegetable consumption could be a strategy for breast cancer prevention.
