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 Positive HER2 Negative 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 Positive HER2 Negative 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 Turnip are recommended when undergoing Tamoxifen treatment for ER PR Positive HER2 Negative Breast Carcinoma. But Roselle and Black Chokeberry are recommended when treatment changes to Letrozole. 

Similarly Neem Extract supplements are recommended with Tamoxifen treatment for ER PR Positive HER2 Negative Breast Carcinoma. But Vitamin E supplements are recommended when treatment changes to Letrozole. So always personalize your nutrition to your cancer gene mutations and other factors.



What is ER PR Positive HER2 Negative Breast Carcinoma?

ER PR Positive HER2 Negative Breast Carcinoma is one of the different subtypes of Breast Carcinoma. This subtype of breast carcinoma is positive for estrogen receptors (ER), and progesterone receptors (PR) but negative 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 Positive HER2 Negative Breast Carcinoma

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

Foods and Supplements contain different active ingredients which manipulate different molecular pathways relevant to cancers such as ER PR Positive HER2 Negative 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 Positive HER2 Negative Breast Carcinoma, cancer pathways or processes like P53 Signaling, Cell Cycle, MYC Signaling, RUNX Signaling, Epithelial to Mesenchymal Transition, Cell Cycle Checkpoints, Replication Stress, WNT Beta Catenin Signaling, Inositol Phosphate Signaling, PI3K-AKT-MTOR Signaling, Notch Signaling, JAK-STAT Signaling, MAPK Signaling, Growth Factor Signaling and Estrogen 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/diet for cancer such as ER PR Positive HER2 Negative Breast Carcinoma depends on the type of cancer, treatments and supplements being taken (if any), age, gender, BMI, lifestyle and any genetic information available.

Foods to Eat After Cancer Diagnosis!

No two cancers are the same. Go beyond the common nutrition guidelines for everyone and make personalized decisions about food and supplements with confidence.


Cancer patients often have to deal with different chemotherapy side effects which affect their quality of life and look out for alternative therapies for cancer. Taking the right nutrition and supplements based on scientific considerations (avoiding guesswork and random selection) is the best natural remedy for cancer and treatment related side-effects.
