Highlights
Nutritional supplements and extracts like Oyster Mushroom have benefits and are used by cancer patients and those at-genetic risk of cancer. There is limited or hardly any clinical data available for use of nutritional supplements and foods in cancer patients. Generating clinical evidence of efficacy for cancer through a randomized clinical trial is further infeasible due to variations in genetics and cancer chemotherapy treatments across cancer patients. Hence a different and new approach is needed to find out for which cancers you should not take Oyster Mushroom supplement and why should not take them?
Is it okay to take Oyster Mushroom extracts or supplements for all cancer indications and any chemotherapy treatment? A common belief but a myth is that everything natural can only be of benefit and do no harm. For example, the use of grapefruit with certain medications is not recommended. Another example is the use of spinach with some blood thinning medications can cause adverse interactions and hence to be avoided. For cancer, nutrition including plant-based foods and supplements can influence outcomes and hence an extremely important decision which needs to be made. Hence NIH-National Cancer Institute has a website for nutrition for cancer care for patients which are generalized recommendations and not personalized for cancer indication and treatments.
A frequently asked question by cancer patients and those at-risk is “What Foods and Nutritional Supplements could be beneficial over others for me?”. “Who should not take an extract or supplement and why?”. Generic guidelines like eating only plant-based-foods or avoiding all sugar or adopting a keto diet is a good start but not actionable and personalized enough.
To find answers to questions on extracts and nutritional supplements and foods requires knowledge of contained active ingredients; genetic mutation prevalence for cancer indication; understanding of underlying cancer biology; chemotherapy treatments and mechanism of actions of active ingredients.
Taking Oyster Mushroom extracts or nutritional supplements may benefit Primary Sinonasal Undifferentiated Carcinoma patients on Radiation treatment over Barberry nutritional supplements. But Oyster Mushroom supplements or Oyster Mushroom extracts offer less benefit if on Bleomycin treatment for Primary Hodgkin Lymphoma compared to Bayberry. Similarly, taking nutritional supplements Oyster Mushroom may benefit healthy individuals who are at genetic risk of cancer due to mutation of gene CTNNB1 over Yarrow Achillea. But avoid nutritional supplements Oyster Mushroom when at genetic risk of cancer due to mutation of gene ERBB2.
The takeaway being – cancer, genomics, treatments and other personalized factors will influence decision making to questions like: Are extracts or nutritional supplements Oyster Mushroom beneficial and should not be taken? Why should Oyster Mushroom be not taken? Who should not take Oyster Mushroom? What are side effects of Oyster Mushroom with Bleomycin chemotherapy? What are the benefits of Oyster Mushroom for cancer? Can Oyster Mushroom help fight cancer and so on.
Whenever there are changes in chemotherapy treatments or cancer tissue genetics – the nutrition may change and hence needs to be re-evaluated. Do consider factors like cancer indication, ongoing chemotherapy treatments and nutritional supplements, age, gender, weight, height, lifestyle and genetics for personalization of nutrition.
Brief Overview
Use of nutritional supplements – vitamins, herbs, minerals, probiotics, and other specialty categories are increasing. Supplements are high concentrations of active ingredients which are also found in different foods. Difference between supplements and foods being that foods contain more than one active ingredient at much lower concentrations. Every active ingredient in an extract or nutritional supplement or food has a unique mechanism of action which can influence nutrition decisions.

These are some example questions which nutrition planning should help answer for you. Should you take supplements Oyster Mushroom? Should you take it when at genetic risk of cancer for mutation of gene CTNNB1? Should you take it when at genetic risk of cancer for mutation of gene ERBB2? Should you take it when diagnosed with Primary Hodgkin Lymphoma? Should you take it when diagnosed with Primary Sinonasal Undifferentiated Carcinoma? Should you take it when on Radiation treatment? Should you continue taking it if you change your treatment from Radiation to Bleomycin? So a general explanation like – it is organic and plant-based or it increases immunity is not sufficient information for making a decision of use of Oyster Mushroom extracts and nutritional supplements.
Cancer
Genetic variations across cancer patients can be different and hence no two cancers are alike. The improved availability of “personalized to genetics” chemotherapy treatments and cancer disease monitoring via blood and saliva have been significant factors to improve outcomes. The earlier the lifestyle and treatment intervention – the better the influence on outcome. Genetic testing has the potential to assess cancer risk and susceptibility early. But for at-risk individuals besides regular monitoring in most cases there are no therapeutic treatment intervention options available. After diagnosis with cancer such as Primary Sinonasal Undifferentiated Carcinoma or Primary Hodgkin Lymphoma, the treatments get personalized to tumor genomics and factors like staging of disease, age and gender. During cancer remission (after treatment cycle is complete) – monitoring is used for assessment of any relapse and accordingly decide on next steps. A large majority of cancer patients and those at-risk may take nutritional supplements like Oyster Mushroom.
So the question is that are all genetic risks and cancer indications to be considered uniformly when making decisions on the use of Oyster Mushroom extracts or nutritional supplements? Are the biochemical pathway implications of genetic risk for cancer due to mutation of gene CTNNB1 the same as due to mutation of gene ERBB2? Are the implications of Primary Sinonasal Undifferentiated Carcinoma the same as Primary Hodgkin Lymphoma? Is it one and the same if you are on treatment with Bleomycin or Radiation?
Oyster Mushroom – An Extract or Nutritional Supplement
Oyster Mushroom supplements contain many active ingredients including Palmitic Acid, Myristic Acid, Glycine, L-leucine and Eicosapentaenoic Acid at different concentration levels. The molecular pathways which are regulated by Oyster Mushroom include Hypoxia, MYC Signaling, Cell Cycle Checkpoints and Focal Adhesion. These biochemical pathways directly or indirectly regulate specific cancer molecular endpoints like growth, spread and death of cancer cells. Because of this biological regulation – for cancer nutrition, the right choice of supplements like Oyster Mushroom individually or in combination is an important decision to be made. When making decisions on the use of supplement Oyster Mushroom over other nutritional supplements – do consider all these factors.
Who Should not take Oyster Mushroom Supplements and Why?
There is no easy way to answer the question “For which cancers should I not chooseOyster Mushroom nutritional supplements”. Just like the same chemotherapy treatment does not work across patients, for similar reasons Oyster Mushroom in comparison with other nutritional supplements may be beneficial or not. Along with which cancer and associated genetics – the ongoing treatments, lifestyle habits, height, weight and food allergies are all factors in deciding if Oyster Mushroom should be avoided or not and why.
1. Will Oyster Mushroom Supplements benefit Primary Hodgkin Lymphoma patients undergoing Bleomycin treatment?
Primary Hodgkin Lymphoma is characterized and driven by specific genetic mutations like ARID1A, ARID5B and B2M leading to biochemical pathway changes in MYC Signaling, Androgen Signaling, Chromatin Remodeling, Suppressive Histone Methylation and Antigen Presentation. A cancer treatment like Bleomycin works through a specific pathway mechanism of action. The goal is to have a good overlap between the treatment and cancer driving pathways for a personalized approach which is effective. In such a condition any food or nutritional supplement which has a contrary effect to the treatment or reduces the overlap should be avoided. As an example, Oyster Mushroom supplement should not be taken for Primary Hodgkin Lymphoma along with treatment Bleomycin. Oyster Mushroom supplement impacts the biochemical pathway called MYC Signaling which either promotes drivers of the disease and/or nullifies the treatment effect. Some of the factors which should be considered when choosing nutrition are type of cancer, treatments and supplements being taken currently (if any
2. Will Oyster Mushroom Supplements benefit Primary Sinonasal Undifferentiated Carcinoma Patients undergoing Radiation Treatment?
Primary Sinonasal Undifferentiated Carcinoma is characterized and driven by specific genetic mutations like GATA1, POLE and ASXL1 leading to biochemical pathway changes in Hypoxia, Chromatin Remodeling, DNA Repair, Oncogenic Cancer Epigenetics and Suppressive Histone Methylation. A cancer treatment like Radiation works through specific pathway mechanisms. The goal is to have a good overlap between the treatment and cancer driving pathways for a personalized approach. In such a condition any food or nutritional supplement which supports treatment action or improves the overlap should be considered. As an example, Oyster Mushroom supplements should be considered for Primary Sinonasal Undifferentiated Carcinoma along with the treatment Radiation. Oyster Mushroom supplement impacts pathways/processes like Hypoxia which either obstruct drivers of Primary Sinonasal Undifferentiated Carcinoma and/or improve Radiation treatment effect.
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. What about Oyster Mushroom Supplements for Healthy Individuals with ERBB2 Mutation associated Genetic Risk?
Different companies offer panels of genes to be tested for assessing genetic risk to different cancers. These panels cover genes associated with cancers of the breast, ovary, uterus, prostate, and gastrointestinal system and others. Genetic testing of these genes may confirm a diagnosis and help guide treatment and management decisions. Identification of a disease-causing variant may also guide testing and diagnosis of at-risk relatives. ERBB2 is one of the genes generally available in panels for cancer risk testing.
ERBB2 mutation causes biochemical pathways/processes like Cell Cycle Checkpoints, Growth Factor Signaling and PI3K-AKT-MTOR Signaling to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Oyster Mushroom should not be taken when the genetic panel identifies mutation of ERBB2 for Esophageal Adenocarcinoma. Oyster Mushroom impacts pathways/processes like Cell Cycle Checkpoints and creates adverse conditions with ERBB2.
4. What about Oyster Mushroom Supplements for Healthy Individuals with CTNNB1 Mutation associated Genetic Risk?
CTNNB1 is one of the genes available in panels for cancer risk testing. CTNNB1 mutation causes biochemical pathways/processes like Focal Adhesion, Adherens junction and Epithelial to Mesenchymal Transition to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Oyster Mushroom supplements may be considered when the genetic panel identifies mutations in CTNNB1 for Adrenocortical Carcinoma. Oyster Mushroom impacts pathways/processes like Focal Adhesion and creates a canceling effect in those individuals with CTNNB1 mutation.
