Making Cancer Decisions Based on Knowledge, Not Fear

When navigating cancer recovery, the sheer volume of information available can feel overwhelming. From cancer nutrition to supplements for cancer patients to alternative cancer therapies, everyone seems to have an opinion—especially in online forums. But how do we separate fact from fear and make decisions that truly serve our individual needs?

The key? Science-based, personalized choices. Let’s explore how to make empowered health decisions without being swayed by misinformation or fear.

One of the biggest challenges many breast cancer patients face is the fear-based messaging surrounding diet, supplements, and lifestyle choices. Many are given lists of foods or supplements to avoid without considering the nuances of how they may actually interact with the body. Two common examples of this are soy and resveratrol supplements and their potential risks in breast cancer—both of which have been debated heavily but ultimately require an individualized approach.

Many breast cancer patients are warned to avoid soy products due to concerns about their estrogen-like properties. However, the reality is more complex than simply eliminating soy from the diet.

• Moderate soy intake has been shown to benefit estrogen-positive breast cancer survivors rather than harm them.
• Whole soy foods—such as tofu, tempeh, and edamame—are nutritionally different from highly processed soy isolates.

Studies show no clear evidence that soy increases breast cancer risk. Some research even suggests it may have protective effects.

• Messina M. (2016) – Soy foods do not increase markers of cancer risk and postdiagnosis soy intake statistically significantly reduces recurrence and improves survival.
• Wei Y, et al. (2020) – Study of 300,000 women shows soy intake is not linked to increased breast cancer risk.

Resveratrol, a powerful antioxidant found in grapes, berries, and peanuts, has been both praised and questioned for its potential impact on cancer. Some fear it might stimulate estrogen receptors, especially in estrogen-positive breast cancer cases. However, newer research provides a more nuanced perspective:

• A 2017 study (Andreani C, et al. (2017)) suggested resveratrol might fuel ER+ breast cancer, but it was conducted in mice, not humans.
• More recent clinical studies suggest potential benefits with no clear increase in estrogen levels.

Some of the more recent research suggests benefit with Resveratrol, but this is still being done in cell lines, so we do have to consider that, just as we did the study above which was in mice.

• Kurzava Kendall L, et al. (2024) – Newer study suggesting potential benefits in reducing cancer cell signalling pathways.
• ALkharashi NA. (2023) – Further evidence supporting its safe use.

Rather than adopting a one-size-fits-all approach, the decision to include or avoid soy and resveratrol, or any other agent (natural or otherwise), should be based on individualized needs, medical history, and consultation with a trusted healthcare professional.

In today’s world, online cancer forums are filled with opinions and personal experiences. While personal stories can be inspiring, they do not always apply to every individual case. Just because someone swears by a certain cancer diet, cancer supplement, or alternative therapy does not mean it is right for everyone.

• Every cancer journey is unique—no two bodies, genetics, or healing paths are the same.
• Cancer cells originate from an individual’s body, carrying unique genetic makeup, meaning a personalized approach is critical.
• Personal limitations and strengths differ—what works for one person may not work for another.

• Scientific – Is this science-based & is this science applicable to me?
• Measurable – Can its impact be tracked?
• Awareness – Is the intervention in line with my values?
• Realistic – Can I feasibly introduce this intervention?
• Transformative – Is the intervention long-lasting & will it change my cancer journey?

By applying individualized medicine to areas such as cancer nutrition, genetic testing (SNP testing), and complementary therapies like mistletoe therapy, the possibilities for personalized healing are extensive.  There are even studies which show there is a need to re-evaluate how evidence-based medicine fits inside individualized cancer treatment (Van de Vliet P, et al. (2023)).

At the end of the day, cancer health decisions should come from a place of empowerment, not fear. It is important to listen, learn, and critically evaluate what applies to your individual situation.
