Mushrooms: Cancer-Causing Or Fighting Superfood?

Mushrooms have been used as a medicinal supplement for centuries in Asia, and they are now being studied for their potential health benefits in the West. There is some evidence that certain types of mushrooms may help to prevent breast cancer, particularly in postmenopausal women with a high body mass index (BMI). However, the available research is limited, and it is not yet clear whether mushrooms can directly cause or cure breast cancer.

Mushrooms are recommended for breast cancer patients

Several studies have shown that the inclusion of mushrooms in the diet can help protect against cancer and reduce the risk of breast cancer. Research has also indicated that consuming mushrooms can lower overall mortality risk. In addition, mushrooms have been shown to have anti-inflammatory and antioxidant effects, which can help reduce inflammation and improve quality of life for cancer patients.

Certain types of mushrooms, such as Reishi (Ganoderma lucidum) and maitake mushrooms, have been found to have specific benefits for breast cancer patients. Reishi extract has been shown to inhibit inflammatory breast cancer (IBC) progression, one of the few foods to demonstrate such an effect. Maitake mushroom supplementation has been found to have both immune-enhancing and immune-suppressant effects, although further research is needed to establish safe and effective dosages.

White button mushrooms have also been the focus of several studies, particularly in Asian countries where their consumption is higher. These studies have found an inverse relationship between white button mushroom consumption and breast cancer risk. The chemicals in these mushrooms have been found to slow the production of estrogen and improve immune function, which can help fight cancer.

Additionally, mushrooms have been used as a complementary treatment to chemotherapy, reducing adverse gastrointestinal effects and improving appetite.

While mushrooms offer potential benefits for breast cancer patients, it is important to note that they should not be considered a sole treatment. It is always advisable to consult with a healthcare professional before incorporating mushrooms or any other dietary supplement into a treatment plan.

Mushrooms may prevent breast cancer

Mushrooms may have the potential to prevent breast cancer. Several studies have shown that the inclusion of mushrooms in one's diet can be protective against cancer. For instance, a study performed on 15,546 participants over 19 years showed that the hazard ratio for overall mortality was lower in subjects who consumed mushrooms regularly. Moreover, the consumption of a daily portion of mushrooms instead of processed or red meat reduced the risk of all-cause mortality to 65%.

In addition, several Asian population studies have reported that higher mushroom consumption is inversely related to breast cancer risk. This is supported by the findings of a study conducted on Korean women, which showed that greater mushroom intake was related to a lower risk of breast cancers among premenopausal women, especially those with hormone receptor-positive tumors.

The potential anticancer effects of mushrooms may be attributed to their ability to stimulate compounds that suppress tumors and decrease inflammatory compounds. For example, Reishi extract has been shown to inhibit inflammatory breast cancer progression, and Shiitake mushrooms have been found to inhibit increases in tumor volume of human breast cancer cells implanted in mice.

Furthermore, mushrooms have been found to have anti-inflammatory and antioxidant effects in patients, and preclinical studies have shown that the introduction of white button mushroom powder inhibited breast tumor development. This suggests that white button mushrooms may modulate the immune cell profile and reduce myeloid-derived suppressor cells, which are elevated in obesity and breast cancer.

While the potential benefits of mushrooms in preventing breast cancer are promising, it is important to note that more research is needed to fully understand their effects. Some studies have also reported adverse reactions to mushroom consumption, such as liver or kidney toxicity, and the impact of mushrooms may vary based on metabolic differences between populations.

Mushrooms can cause adverse reactions

Mushrooms have been shown to have a positive effect on breast cancer patients, with studies indicating that they can slow tumour growth and reduce inflammation and immune compounds. However, it is important to note that mushrooms can also cause adverse reactions in some individuals.

Mushrooms are known to contain potent biological compounds, and as such, they can behave like drugs in the body. In some cases, this can lead to mild to moderate liver or kidney toxicity. While these side effects are typically not severe, they should still be considered when incorporating mushrooms into one's diet or treatment plan.

The effects of mushrooms may vary depending on the type of mushroom, dosage, and individual factors such as metabolism and enzyme levels. For example, maitake mushroom supplementation has been shown to have both immune-enhancing and immune-suppressant effects at various doses. Similarly, shiitake mushrooms, while inhibiting increases in tumour volume, also contain relatively high levels of copper, which has been linked to increased angiogenesis and metastasis of breast cancer in women with inflammatory breast cancer or triple-negative disease.

Additionally, raw white button mushrooms have been shown to cause various cancers in mice due to their agaritine content, a type of mycotoxin. However, it is important to note that cooking neutralizes the agaritine and eradicates any pathogenic bacteria on the surface of the mushrooms.

Therefore, while mushrooms may offer potential benefits in the context of breast cancer, it is crucial to thoroughly cook them and to consult with a doctor before incorporating them into one's treatment plan to ensure safe and effective usage.

Mushrooms can slow the production of estrogen

Mushrooms have been used as a medicinal supplement for centuries, especially in Asia. In recent years, they have been studied for their potential health benefits, including their ability to slow the progression of certain cancers.

Breast cancer is one of the leading causes of death in women worldwide, and research has shown that the inclusion of mushrooms in the diet may be protective against this disease. Several studies have found an inverse relationship between mushroom consumption and breast cancer risk, suggesting that eating mushrooms may lower the chances of developing breast cancer.

One of the mechanisms by which mushrooms may exert their protective effects against breast cancer is by slowing the production of estrogen. Estrogen is a hormone that plays a crucial role in the development and progression of breast cancer, especially in hormone receptor-positive tumors. By slowing down estrogen production, mushrooms may help reduce the risk of hormone-driven breast cancers.

This effect on estrogen production is particularly notable in white button mushrooms, which have been the focus of several studies. Research has indicated that the chemicals present in white button mushrooms can slow the production of estrogen, as well as DHT, another hormone that influences cancer development. The intake of these mushrooms has also been linked to improved immune function, which may further contribute to their cancer-fighting properties.

While the research on the cancer-fighting properties of mushrooms is promising, it is important to note that the majority of studies have been conducted in Asian countries, where mushroom consumption is generally higher. More research is needed to determine the exact mechanisms by which mushrooms exert their protective effects and to establish safe and effective dosages for supplementation.

Medicinal mushrooms can be used alongside cancer treatments

Mushrooms have been used in traditional medicines in East Asia for hundreds of years due to their immunomodulatory, anticancer, and anti-inflammatory activities. There are more than 100 types of mushrooms used to treat cancer in Asia, and some of the common ones are Ganoderma lucidum (reishi), Trametes versicolor or Coriolus versicolor (turkey tail), Lentinus edodes (shiitake), and Grifola frondosa (maitake).

Mushrooms are packed with vitamin D, which is essential for the immune system. Certain mushrooms stimulate the compounds responsible for tumor suppression, while some decrease inflammatory compounds, which is helpful for cancer patients. In addition, mushrooms have been linked to improvements in several common quality of life indicators for cancer patients, such as improved appetite, improved physical and mental competency, and reduced fatigue.

In a randomized, double-blind, placebo-controlled trial performed on 46 breast cancer patients (stages II and III) receiving a supplement of Agaricus sylvaticus (2.1 g daily) during chemotherapy, the mushroom supplement was found to have a protective effect against various gastrointestinal adverse events caused by chemotherapy.

Reishi extract has been shown to be effective in inhibiting inflammatory breast cancer (IBC) progression, and it is one of the few foods to have demonstrated beneficial impacts on this highly aggressive form of cancer. However, it should be avoided by those with ER+ breast cancer, except for those with IBC.

Medicinal mushrooms can boost the immune system and have been approved as an addition to standard cancer treatments in Japan and China for more than 30 years. Turkey tail, for example, has been used to strengthen the immune system in Japan when given with standard cancer treatment. Polysaccharide K (PSK) is the best-known active compound in turkey tail mushrooms, and it is an approved mushroom product used to treat cancer in Japan.

In summary, medicinal mushrooms can be used alongside cancer treatments to improve quality of life, boost the immune system, and reduce side effects of chemotherapy. However, it is important to consult a doctor before using mushrooms during cancer treatment, as they contain potent biological compounds and should be treated like medication.
