Study for the Knowledge of Risk Factors Associated With Breast Cancer in Women (Mamanut)

Observational Study to Understand the Risk Factors Associated With Breast Cancer in Women With a Recent Diagnosis at the Community of Madrid

Breast cancer is the most frequent tumor in Western women. In Spain about 26,000 new breast cancers are diagnosed each year. This type of tumor is increasing worldwide with an increase in aggressive neoplasms in young women. There are some risk factors responsible for this global increase: lifestyle, diet and body weight especially in postmenopausal women.

Some cell mutations, especially in the BRCA1, BRCA2 and p53 genes, are associated with a very high risk of this type of cancer. Some authors have calculated the contribution of various modifiable risk factors to the global burden of breast cancer, and they concluded that 21% of all breast cancer deaths are attributable to alcohol consumption, overweight and obesity, and lack of physical activity. Nowadays, there aren't specific studies in the Community of Madrid designed to know the risk factors related to breast cancer.

For this reason, it is proposed to carry out an observational study that collects detailed information about dietary habits, genetic factors and life quality of a group of women with recent diagnosis in pre or post-surgical phase.

Study Overview

• Status: Completed
• Conditions: Breast Neoplasm Female; Cancer, Breast; Nutrition Related Cancer; Habits, Diet

6. Anthropometric study: weight, size, waist circumference and body composition (% Fat mass,% Lean mass,% Body water).
7. Study of other risk factors of breast cancer: age, family history, reproductive history, medications consumed...
8. Biochemical study: biochemical variables of the last blood analysis performed on the volunteer in the hospital center.
9. Saliva collection to proceed with the genetic analysis.
10. Collection of stool sample to carry out the microbiota study.
