Mushrooms have long been used as medicine, especially in Asia, where they have been used to treat infections and lung diseases for hundreds of years. In Japan and China, mushrooms have been approved as an addition to standard cancer treatments for over 30 years. Polysaccharide K (PSK), found in turkey tail mushrooms, is used in Japan to treat cancer. However, there is limited information on the teratogenic effects of mushroom mycotoxins, and some studies indicate that raw mushrooms can induce cancer in experimental animals. While some studies suggest that mushroom consumption may lower the risk of certain cancers, others show no association between mushroom intake and cancer risk. The impact of mushrooms on cancer may depend on the broader context of an individual's diet and activity regime.

What You'll Learn
Some studies suggest eating mushrooms may reduce cancer risk
Mushrooms are a part of the fungus family and are considered a healthy food. They are low in fat and sugar and contain fibre, minerals, vitamins, and bioactive compounds. They are also a good source of vitamins B and D, riboflavin, niacin, vitamin D, selenium, potassium, and amino acids.
Some studies suggest that eating mushrooms may reduce cancer risk. A study by Penn State College of Medicine researchers found that higher mushroom consumption is associated with a lower risk of cancer. The study, published in Advances in Nutrition, examined 17 cancer studies from 1966 to 2020 and analysed data from more than 19,500 cancer patients. The researchers found that individuals who ate 18 grams of mushrooms daily (about 1/8 to 1/4 cup) had a 45% lower risk of cancer compared to those who did not eat mushrooms. The researchers also found that mushrooms are the highest dietary source of ergothioneine, a unique and potent antioxidant that may help protect against oxidative stress and lower the risk of cancer.
In traditional Chinese medicine, certain types of mushrooms, such as Ganoderma lucidum (reishi), Trametes versicolor or Coriolus versicolor (turkey tail), Lentinus edodes (shiitake), and Grifola frondosa (maitake), have been used to treat cancer for hundreds of years. In Japan, Polysaccharide K (PSK), an active compound found in turkey tail mushrooms, is an approved mushroom product used to treat cancer. Laboratory and animal studies have shown that PSK can strengthen the immune system and may have anticancer effects.
While these studies suggest that mushrooms may have potential cancer-fighting properties, it is important to note that the evidence is not conclusive. More research is needed to determine the specific mechanisms and cancers that may be impacted. Additionally, it is important to consider mushroom intake within the broader context of a person's diet and lifestyle, as cancer risk is likely influenced by a combination of factors.

Medicinal mushrooms have been used to treat cancer in Asia
Mushrooms are part of the fungus family and there are hundreds of different species. They have been used in traditional Chinese medicine and other traditional medicines for hundreds of years to treat illnesses. They are also known as medicinal mushrooms. However, it is important to note that some species of mushroom are not edible.
Medicinal mushrooms have been used as an addition to standard cancer treatments in Asia, particularly in Japan and China. In these countries, mushrooms have been used safely for a long time, either alone or in combination with radiation or chemotherapy. There are more than 100 types of mushrooms used to treat cancer in Asia. Some of the more common ones are Ganoderma lucidum (reishi), Trametes versicolor or Coriolus versicolor (turkey tail), Lentinus edodes (shiitake), and Grifola frondosa (maitake).
Reishi mushrooms have been used in medicine in East Asia for a long time. It was thought to prolong life, prevent aging, and increase energy. In China, it is used to strengthen the immune system of cancer patients who receive chemotherapy or radiation therapy. Reishi is usually dried and taken as an extract in the form of a liquid, capsule, or powder. Laboratory and animal studies have been conducted using reishi to test its potential anticancer effects.
Turkey tail mushrooms, also known as Coriolus versicolor, have been used in traditional Chinese medicine to treat lung diseases for many years. In Japan, it is used to strengthen the immune system when given with standard cancer treatment. Polysaccharide K (PSK) is the best-known active compound in turkey tail mushrooms. PSK is an approved mushroom product used to treat cancer in Japan and can be taken as a tea or in capsule form. Laboratory and animal studies have been conducted to test its effects on the immune system, including immune cells called natural killer cells and T-cells.
While medicinal mushrooms have been used to complement cancer treatments in Asia, it is important to note that there is currently no evidence that mushrooms or mushroom extract can prevent or cure cancer. However, research suggests that they may strengthen the immune system, and studies are ongoing to determine their potential antitumor effects.

Mushrooms are being studied for their anti-tumour effects
Mushrooms are being studied for their potential anti-tumour effects. While they are not a cure for cancer, research has shown that they may slow the growth of tumours or kill tumour cells. Polysaccharide K (PSK), a compound found in turkey tail mushrooms, is one substance that has been studied for its anti-tumour effects. In Japan, PSK is an approved mushroom product used to treat cancer and has been shown to improve immune function, body weight, well-being, and tumour-related symptoms in patients. Laboratory and animal studies have also been conducted to test the effects of PSK on the immune system, including immune cells called natural killer cells and T-cells.
Reishi mushrooms, another type of medicinal mushroom, have been used in traditional Chinese medicine for centuries and are believed to have immune-boosting properties. Studies suggest that reishi may help strengthen the immune system in patients with lung cancer, particularly those receiving chemotherapy or radiation therapy.
Shiitake mushrooms, native to East Asia, are also valued for their potential health benefits, including anti-cancer properties. Shiitake extract, lentinan, is a type of complex sugar compound known as a beta glucan that may stimulate the immune system and slow the growth of cancer cells.
While the research on the anti-tumour effects of mushrooms is promising, it is important to note that the studies conducted thus far have been relatively small and more research is needed to confirm these findings. Additionally, it is worth noting that the anti-tumour effects of mushrooms may vary depending on the type of cancer and other factors.

Raw mushrooms have been linked to cancer in mice
While mushrooms have been linked to cancer prevention, there is some evidence to suggest that raw mushrooms may have cancer-causing properties.
Agaricus bisporus and Gyromitra esculenta are two types of raw mushrooms that have been found to induce cancer in experimental animals. In mice, a study found that a daily intake of 4 grams of mushrooms resulted in a risk of 2 cancerous events per 100,000 lives. However, it is important to note that the results of animal studies may not be directly applicable to humans.
When scaled up to human-sized doses, the risk of cancer from consuming raw mushrooms is negligible. To reach the equivalent dose, a human would need to consume 1.5 to 10 kilograms of mushrooms per day, which is a significantly larger amount than the average person consumes.
Additionally, the existing evidence on the cancer-causing effects of raw mushrooms is limited and may not be sufficient to draw definitive conclusions. Retrospective case-control studies, which have suggested a link between high mushroom consumption and a reduced risk of breast cancer, are prone to selection and recall biases. On the other hand, prospective cohort studies have found no association between mushroom consumption and the risk of total or site-specific cancers.
Medicinal mushrooms have been used as a complementary treatment for cancer in Asia, particularly in Japan and China. These mushrooms are believed to strengthen the immune system and may have antitumor effects. However, more research is needed to fully understand the impact of mushrooms on cancer risk and treatment.
In conclusion, while raw mushrooms have been linked to cancer in mice, the risk to humans is minimal and there is insufficient evidence to suggest that raw mushrooms are carcinogenic. However, further studies are warranted to comprehensively understand the relationship between mushroom consumption and cancer risk.

Mushrooms contain nutrients, vitamins and antioxidants
Mushrooms are native to North America and Europe and are known for their delicate flavour and meaty texture. They are also widely known for their amazing health benefits. Mushrooms are packed with essential vitamins, minerals, and antioxidants, which make them an excellent addition to a healthy diet.
Mushrooms contain many important nutrients, including riboflavin, niacin, vitamin D, fibre, selenium, potassium, and bioactive compounds. Selenium can help prevent cell damage in our bodies, vitamin D helps with cell growth, and vitamin B6 helps our bodies form red blood cells. All of these nutrients help to maintain a healthy immune system. Mushrooms are also a good source of potassium, which is known for reducing the negative impact of sodium on the body.
The nutritional profiles of mushrooms vary between types. For example, dried mushrooms contain vitamin D2, while cremini mushrooms are an excellent source of zinc, which is an important nutrient for the immune system and is needed for optimal growth in infants and children. Lion's mane mushrooms contain two compounds that can stimulate the growth of brain cells: hericenones and erinacines. Chaga mushrooms may have a range of health benefits, from lowering blood pressure to preventing cancer. Reishi mushrooms have many purported benefits, including boosting the immune system and shrinking tumours.
Mushrooms are also used medicinally and have been used to treat infections for hundreds of years, mostly in Asia. Medicinal mushrooms are also used to treat lung diseases and cancer. For more than 30 years, medicinal mushrooms have been approved as an addition to standard cancer treatments in Japan and China. Polysaccharide K (PSK) is the best-known active compound in turkey tail mushrooms. In Japan, PSK is an approved mushroom product used to treat cancer and can be taken as a tea or in capsule form.

Frequently asked questions
There is no clear answer to this question. While some studies have found that eating mushrooms may reduce the risk of certain cancers, others have suggested that certain raw mushrooms and chemicals found in mushrooms can induce cancer in experimental animals.
No, not all mushrooms have been found to have anti-cancer properties. For example, while shiitake, oyster, maitake, and king oyster mushrooms have higher amounts of the amino acid ergothioneine, a potent antioxidant, other varieties such as white button, cremini, and portobello mushrooms have lower amounts.
Yes, studies have been conducted in China and Japan using products made from reishi mushrooms as adjuvant therapy to strengthen the immune system in patients with lung cancer. Additionally, Polysaccharide K (PSK), a compound found in turkey tail mushrooms, is approved in Japan as a mushroom product used to treat cancer.
While some studies suggest that consuming mushrooms may reduce the risk of certain cancers, it is important to note that the evidence is not conclusive. Retrospective case-control studies, which have shown a link between mushroom consumption and reduced breast cancer risk, are prone to selection and recall biases. Therefore, more prospective studies in diverse populations are needed to fully understand the role of mushroom consumption in cancer development.
According to one study, participants who consumed more mushrooms tended to have higher physical activity levels, used multivitamins, and had a better overall diet quality. They also tended to undergo more frequent cancer screenings and were less likely to be smokers. Therefore, including mushrooms in a healthy lifestyle that includes regular physical activity, a balanced diet, and cancer screenings may be beneficial in reducing the risk of certain cancers.
