Highlights

Banana like other plant based foods have health benefits and is included in the diet of cancer patients and those with genetic risk of cancer. But, the intake of Banana may need to be reduced for some cancers and cancer treatments. A belief but a myth is that everything plant based can only benefit and do no harm. That is true if the food intake is in moderation. For example, grapefruit with certain medications is not recommended. Also spinach with some blood thinning medications can cause adverse interactions and hence intake should be reduced. For cancer, nutrition which includes food and supplements are important decisions which need to be made. Hence the frequently asked question related to cancer is “What Food Should I Eat and What Should I Avoid?”.

Benefits of foods like Banana can be scientifically explained for cancer patients with PIK3CA+ Gallbladder Cancer taking Cisplatin treatment. But reduce intake of Banana for FGFR+ Hepatocellular Carcinoma and Bevacizumab treatment . 

Similarly, the benefits of eating Banana can be scientifically explained for healthy individuals who are at genetic risk of cancer due to mutation of the gene ALK. But reduce intake of Banana when at genetic risk of cancer due to mutation of gene BRIP1. 

The takeaway being – for cancer individual conditions can influence if food like Banana is recommended or not. As conditions like ongoing treatments and supplements change the nutrition plan must be personalized again. Which cancer, current treatments and supplements, age, gender, weight, height, lifestyle and genetic conditions are decision factors for your nutrition. 



Why is the choice of foods important for cancer?

Foods typically contain more than one active ingredient at varying concentrations. Each of these active ingredients has a unique molecular biological mechanism of action. Cancer like most diseases is driven by specific biochemical pathways and molecular interventions of the pathway can be beneficial or create adverse interactions. Hence for cancer there is a need to personalize which foods and supplements to take and check if foods like Banana are recommended. 

 Banana for Cancer Treatment and Genetic Risk

So some of the example questions you may have related to Banana can be: Should you eat it when at genetic cancer risk due to mutation of gene BRIP1? Should you eat Banana when a mutation of a gene ALK is identified? Should you eat Banana when diagnosed with FGFR+ Hepatocellular Carcinoma? Should you eat Banana when diagnosed with PIK3CA+ Gallbladder Cancer? Should you eat Banana when on Bevacizumab treatment? Should you continue eating Banana if your treatment changes from Bevacizumab to Cisplatin? Are the implications of taking Banana in PIK3CA+ Gallbladder Cancer the same as FGFR+ Hepatocellular Carcinoma? And so on.

Banana and cancer

Bananas are native to Southeast Asia, but are one of the most popular fruits consumed across the world. They are packed with nutrients and high in fiber and antioxidants. Following are some of the potential health benefits of bananas (Ana Luisa Falcomer et al, Nutrients., 2019)

  • May help reduce gastrointestinal symptoms
  • May aid in weight control
  • May help reduce kidney and liver complications associated to diabetes

Banana contains many active ingredients like Linoleic Acid, Vitamin A and Beta-sitosterol at different concentrations. The molecular pathways which are regulated by Banana include Cell Cycle Checkpoints, Stem Cell Signaling, Notch Signaling, JAK-STAT Signaling, Focal Adhesion, Apoptosis and Angiogenesis. These cellular pathways directly or indirectly influence cancer molecular endpoints like growth, spread and death. Because of this biological relationship – for cancer, choosing foods like Banana and supplements is an important decision to be made. And not necessarily the same food choices are scientifically correct across individuals.

Include Banana in Your Cancer Nutrition?

The answer to the question “Which Foods to Eat” and “Which Foods to Reduce Intake of” is It Depends!. Just like the same treatment does not work for every cancer patient, based on individual context the Banana may have scientific benefits or have adverse interactions. Along with cancer  – the ongoing treatments, supplements, lifestyle habits, height, weight, allergies and food preferences are all factors influencing answers to the question. 

1. Continue Eating Banana for FGFR+ Hepatocellular Carcinoma and Bevacizumab treatment?

FGFR+ Hepatocellular Carcinoma is defined and driven by specific genetic mutations like FGFR2 and TP53 leading to biochemical pathway changes in Focal Adhesion, Notch Signaling, Extracellular Matrix Remodelling, PI3K-AKT-MTOR Signaling and Small Molecule Transport. A cancer treatment like Bevacizumab has molecular action on a unique set of biochemical pathways. The treatment intent is to have a good overlap between the cancer driving pathways and those manipulated by the treatment. In such conditions foods which have an opposing effect to the treatment and reduce the overlap between the cancer driving pathways and treatment should be avoided. As an example, Banana intake should be reduced by cancer patients with FGFR+ Hepatocellular Carcinoma while on Bevacizumab treatment. Banana impacts pathways or processes like Focal Adhesion and Notch Signaling which can negate the effects of the treatment. The factors to be considered when choosing foods and supplements are which cancer, treatments and supplements being taken currently, which age group, gender, height, weight, lifestyle habits and any genetic information.

2. Continue Eating Banana for PIK3CA+ Gallbladder Cancer and Cisplatin treatment?

PIK3CA+ Gallbladder Cancer is defined and driven by specific genetic mutations like PIK3CA and TP53 leading to biochemical pathway changes in Apoptosis, Cell Cycle Checkpoints, P53 Signaling, PI3K-AKT-MTOR Signaling and MYC Signaling. A cancer treatment like Cisplatin has molecular action on a unique set of biochemical pathways. Banana should be considered by cancer patients with PIK3CA+ Gallbladder Cancer while on Cisplatin treatment. Banana impacts pathways or processes like Apoptosis and Cell Cycle Checkpoints which can either obstruct drivers of PIK3CA+ Gallbladder Cancer and/or improve Cisplatin treatment effect.

For which cancers should Banana be avoided

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.

3. Continue Eating Banana for BRIP1 Associated Cancer Genetic Risk? 

Many companies offer gene panels testing for evaluating genetic risk to different cancers. These panels cover genes associated with high prevalence cancers of breast, ovary, uterus, prostate and gastrointestinal system and others. Testing of these genes may confirm a diagnosis or identify risk to some cancers. BRIP1 is one of the genes available in panels for cancer risk testing. 

BRIP1 mutation causes biochemical pathways or processes like Angiogenesis, Stem Cell Signaling, Chemokine Signaling, Estrogen Signaling and P53 Signaling to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Intake of foods like Banana should be reduced when mutation of BRIP1 for risk of Ovarian Cancer is identified. Banana impacts pathways or processes like Angiogenesis and Stem Cell Signaling and creates adverse effects with BRIP1 mutation and related conditions.

4. Continue Eating Banana for ALK Associated Cancer Genetic Risk? 

ALK is also one of many genes available in panels for cancer risk testing. ALK mutation causes biochemical pathways or processes like Angiogenesis, JAK-STAT Signaling, Stem Cell Signaling and Growth Factor Signaling to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Intake of foods like Banana should be considered when mutation of ALK for risk of Central Nervous System is identified. Banana impacts pathways or processes like Angiogenesis and JAK-STAT Signaling and creates a supportive effect in those with ALK mutation and related conditions.

* Other Factors Included Like BMI, Lifestyle Habits, Treatments

In Conclusion 

Nutrition for cancer (including supplements and foods like Banana) and treatments may not be the same for everyone. 

What food you eat and which supplements you take is a decision you make. Your decision should include consideration of the cancer gene mutations, which cancer, ongoing treatments and supplements, any allergies, lifestyle information, weight, height and habits.

The nutrition planning for cancer from addon is not based on internet searches. It automates the decision making for you based on molecular science implemented by our scientists and software engineers. Irrespective of whether you care to understand the underlying biochemical molecular pathways or not - for nutrition planning for cancer that understanding is needed.

Get started NOW with your nutrition planning by answering questions on the name of cancer, genetic mutations, ongoing treatments and supplements, any allergies, habits, lifestyle, age group and gender.

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.
