“…Diet is widely discussed as a modifiable determinant for cancer, as healthy dietary patterns seem to be related to decreased risk of colon and breast cancer and unhealthy dietary patterns can lead to increased risk of colon cancer ( 42 , 43 ). However, it can no longer be generalized about different cancer types and varied target populations, since these results are inconsistent with some of previous studies ( 44 - 46 ). There may not be correlations between unhealthy dietary pattern and risk of upper digestive tract, pancreatic, ovarian, endometrial, and prostatic cancers based on case-control studies ( 44 , 47 ).…”

There is a large body of evidence on a correlation between dietary intakes and all types of cancer. →What this article adds:The association between dietary patterns, diet quality index, and dietary inflammatory index with cancer incidence was assessed in the present article. The Western dietary pattern, inflammatory diet, and lower adherence to the Mediterranean dietary pattern contribute to 23%, 16%, and 27% higher cancer risk, respectively.

“…This is probably related to the relatively high price of fish compared to meat and the lack of public awareness on the health benefits from fish. Possibly associated with low fish consumption may also be the fact that there is fear of pollution in the sea; however, many studies have shown that the health benefits of eating fish to a large extent outweigh the risks (49).…”

Background/Aim: Breast cancer is the most common type of cancer among women around the world and the leading cause of cancer-related death among women. The knowledge about modifiable risk factors, such as diet, can be an acceptable, cheap and non-pharmacological prevention tool. The aim of this study was to investigate the association between dietary fat, dietary fatty acids, fish intake, and breast cancer in women. Patients and Methods: A case-control study was designed. A total of 201 consecutive, newly diagnosed, polish female cancer patients (mean age: 58 years) and 201 one-to-one age-matched controls were enrolled. A standardised questionnaire assessing various sociodemographic, clinical, lifestyle, and dietary characteristics was applied via face-to-face interviews. Detailed dietary intake information was assessed using a validated Food Frequency Questionnaire. Odds ratios (OR) and 95% confidence intervals (95%CI) were obtained using multiple unconditional logistic regression models controlling for nondietary and dietary potential confounders. Results: Consumption of polyunsaturated fats (PUFA) over 10% of total energy intake was associated with a significantly lower risk of breast cancer compared to low intake of PUFA (OR=0.4, 95%CI=0.19-0.85). Low (<0.2) omega-3/ omega-6 ratio (OR=2.04, 95%CI=0.996-4.17), fish consumption less than once every six months (OR=3.37, 95%CI=1.57-7.23) and being overweight (OR=2.07, 95%CI=1.3-3.3) were associated with increased risk of breast cancer. Residents of rural areas had a significantly higher risk compared to women from urban areas (OR=1.8, 95%CI=1.06-3.03). Conclusion: High intake of PUFA can decrease the risk of breast cancer, while the low omega-3/omega-6 ratio increases the risk. In addition, overweight state, eliminating fish from the diet and living in rural areas can also increase the risk of breast cancer. Breast cancer is the most common type of cancer among women around the world and the leading cause of cancerrelated death among women. In 2018, 2.1 million new cases were diagnosed worldwide, while in the same year breast cancer was the cause of approximately 627 thousand deaths (1-3). In Poland the number of newly registered cases is constantly growing (4). Every year 18 thousand women are diagnosed with breast cancer, which accounts for 22% of all types of cancer among Polish women (5, 6). While known risk factors for breast cancer, such as: age over 40 years, positive family history, early menstruation, late menopause, late age of first pregnancy (after the age of 35 years), duration of breastfeeding, and Caucasian race (7, 8) are basically unmodifiable, the knowledge of nutritional recommendations and the awareness that the diet has an impact on the risk of developing this type of cancer (7, 9) may be harbingers of a new primary prevention system. Many studies have drawn special attention to dietary fat and fatty acids (10-14); however, they do not provide a definitive answer to the question of the role of fat in the aetiology of breast cancer.
