Volatile organic compounds (VOCs) are low molecular weight (<1 kDa) compounds which represent the final products of cell metabolism. Their composition can be affected by several factors including diet, hormones, environment and the presence of diseases, in particular, cancer.

Breast cancer (BC) is leading cancer in women. As most of the cancers, it is characterized by inflammation and alternations in lipid and fatty acid metabolism. Patients with BC have impaired fatty acid profiles, low level of PUFAs, and high n-6/n-3 PUFAs ratio. Moreover, these changes are related to
Cancers are characterized by inflammation and alternations in lipid and fatty acid metabolism. Patients with non-Hodgkin lymphoma have impaired fatty acid profiles, low level of PUFAs, and high n-6/n-3 PUFAs ratio. Moreover, these changes are related to clinical outcome.

Oral health, specifically the retention of teeth, is inextricably and positively linked with nutritional status of an individual. The emerging inter-relationships among obesity, type II diabetes metabolic syndrome, acute coronary syndrome and/or breast cancer with the etiology of periodontal disease
The study aims to determine biological changes that occur with a 12 month intervention of low (~0.9 g EPA+DHA/day) vs high dose (~5.4 g EPA+DHA/day) of omega 3 polyunsaturated fatty acids (PUFAs) in women survivors of hormone unresponsive breast cancer. The objectives of the trial are to develop
PRIMARY OBJECTIVES:
I. To determine if omega-3 dietary supplementation (omega-3 fatty acid) results in higher polyunsaturated fatty acids (PUFA) levels in surgical specimens of normal and malignant breast tissue in women who took omega 3 tablets in comparison to those who took placebo.
II. To
Local relapses and metastases make breast cancer a deadly disease. A major goal remains the improvement of treatment efficacy, meaning increasing toxicity to tumor tissue, without additional toxicity to non-tumor tissues.
The literature indicates that DHA sensitizes breast malignant tumors, but not
Cancer is accompanied by increased oxidative stress and induction of polymorphic cytochrome P- 450 mixed oxidase enzymes (CYP). Both processes affect the abundance of volatile organic compounds (VOCs) in the breath because oxidative stress causes lipid peroxidation of polyunsaturated fatty acids in
OBJECTIVES:
- To determine the effect of omega-3 fatty acids on markers of breast cancer progression in women with newly diagnosed ductal carcinoma in situ and/or atypical ductal hyperplasia.
- To determine the effect of omega-3 fatty acids on specific targets identified by microarray in breast
