Highlights

No two cancers are the same and neither should your nutrition be. When diagnosed with cancer or at risk of cancer – one immediate question is “What Should I Eat Differently Starting Now?” and “Which Supplements Should I Take and Avoid”. The answer is “It Depends”. It depends on which genetic mutations your tests identified. It depends on which cancer, which ongoing treatments and supplements. It depends on your age, weight, height, lifestyle, allergies and habits. The answer to “What Should I Eat Differently” and “Which Supplements Should I Take and Avoid” for ER PR Negative HER2 Positive Breast Carcinoma also requires understanding of how the food and supplements included in your diet manipulate the molecular pathways which are relevant for cancer and interactions with your treatment.

Internet search to find answers will never be personalized to your cancer type such as ER PR Negative HER2 Positive Breast Carcinoma and lifestyle conditions. Cancers are driven by biochemical pathways and therefore the answers to nutrition questions have to be based on molecular science irrespective of whether one understands it or not.  

For example foods like Cabbage and Tomato are recommended when undergoing Trastuzumab treatment for ER PR Negative HER2 Positive Breast Carcinoma. Similarly Tangerine supplements are recommended with Trastuzumab treatment for ER PR Negative HER2 Positive Breast Carcinoma. So always personalize your nutrition to your cancer gene mutations and other factors.



What is ER PR Negative HER2 Positive Breast Carcinoma?

ER PR Negative HER2 Positive Breast Carcinoma is one of the different subtypes of Breast Carcinoma. This subtype of breast carcinoma is negative for estrogen receptors (ER) and progesterone receptors (PR), but positive for HER2 protein overexpression.  The defects or aberrations or mutations in these genes can either drive cancer (tumor promoters) or remove brakes on cancer progression (tumor suppressors). You can visit NIH for information on the prevalence of genetic mutations across cancers. (Reference: Steven N Hart et al, Hum Mutat,. 2020)

Diet for ER PR Negative HER2 Positive Breast Carcinoma

Why Are Some Foods Recommended in the Diet for ER PR Negative HER2 Positive Breast Carcinoma?

Foods and Supplements contain different active ingredients which manipulate different molecular pathways relevant to cancers such as ER PR Negative HER2 Positive Breast Carcinoma. Genetic mutations and cancer conditions cause specific molecular pathways to become disrupted. Hence, those foods and supplements are recommended which do not disrupt those molecular pathways further and instead reverse the disruption. For ER PR Negative HER2 Positive Breast Carcinoma, cancer pathways or processes like Cell Cycle, MYC Signaling, Adherens junction, RUNX Signaling, Epithelial to Mesenchymal Transition, WNT Beta Catenin Signaling, RAS-RAF Signaling, Inositol Phosphate Signaling, PI3K-AKT-MTOR Signaling, Notch Signaling, JAK-STAT Signaling, MAPK Signaling and Growth Factor Signaling get disrupted. Choose those foods and supplements which contain active ingredients which cancel the molecular pathways disruption. Those supplements which interact with the treatments and disrupt the cancer molecular pathways further should be avoided.

The nutrition for cancer such as ER PR Negative HER2 Positive Breast Carcinoma depends on the type of cancer, treatments and supplements being taken (if any), age, gender, BMI, lifestyle and any genetic information available. 

Example Foods to Eat with Trastuzumab treatment for ER PR Negative HER2 Positive Breast Carcinoma

Foods and Supplements to take and avoid for ER PR Negative HER2 Positive Breast Carcinoma

Recommended Foods
