Colorectal cancer

What is colorectal cancer?

The rectum is the last inches of the large intestine. It begins at the end of the final segment of the colon and ends in the narrow, short tube that reaches the anus.

Cancer inside the rectum (cancer of the rectum) and cancer within the colon (colon cancer) are often called “colorectal cancer” together.

Although colon cancer and rectal cancer are similar in several aspects, their treatments are quite different. This is mainly because the rectum is located in a narrow place, barely separated from other organs and structures of the pelvic area. Therefore, a complete surgical removal of rectal cancer is difficult and very complex. Additional treatment is often needed pre or post-surgery to reduce the chance that the cancer will come back.

In the past, the long-term survival of people suffering from rectal cancer was not common, even after prolonged treatment. Advances over the last 30 years in treatment, mean that many cases of rectal cancer can now be be cured.

Expert Advice

Our professional mycotherapy specialist advisors can provide tailored advice and mycotherapy protocols using Hifas da Terra organic mushroom products.

Which mushrooms have useful properties for colorectal cancer?

Through the selected fungi we intend a better response to conventional treatment and reduce the associated effects associated with these treatments.
The nutritional deficiencies of the oncological patient are a complex phenomenon, of multifactorial etiology and of important clinical consequences, which have an inseparable relationship with the severity of the disease.

By improving the nutritional status of the patient we improve their immune response and with it the risk of opportunistic infections and side effects.
There are data that justify the use of fungal extracts as a complement in chemotherapy treatments to reduce pain, cachexia and side effects (loss of hair and appetite, vomiting, etc.).

Reishi Hifas da Terra: useful properties


Patients treated with Reishi were more likely to respond positively to chemotherapy or radiation therapy compared to those who received only chemo or radiotherapy.

Oncological patients treated with Reishi show a considerable increase in the percentages of lymphocytes, an improvement in the quality of life and a reduction in side effects (nausea and insomnia) compared to the untreated ones.

Reishi contains biologically active compounds against the estrogen-mediated signaling system in tumor cells involved in this type of tumor.

The extract of Reishi has demonstrated sedative and anti-inflammatory capacity, as well as an increase in the total time of sleep, improving the quality of life.

Royal Sun Agaricus

The Mushroom extract of the sun produces improvements in appetite, alopecia, emotional stability and general weakness in gynecological patients undergoing chemotherapy.


The extract of Grifola frondosa is able to produce symptomatic improvements or regression of cancer in 68.8% of patients with breast cancer.


The extract of Coriolus versicolor (PSK) is able to improve the survival of patients with different types of cancer (mean 9% increase in overall survival and disease-free survival at 5 years) used in combination with chemotherapy against pharmacological treatment isolated.

Lion's Mane Hifas da Terra

Lion’s mane

Lion’s mane inhibits the growth of gastric, liver and colon cancer cell lines. In addition, it relieves abdominal pain and reduces precancerous cell growth and inflammation in patients with inflammatory bowel disease or chronic gastritis.

Oyster mushroom

The bioactive polysaccharides present in the Seta of the present antiproliferative activity against gastric and colon cancer cell lines, as well as prebiotic activity.

King Trumpet Mushroom

The series of carts is able to reduce the number of precancerous lesions induced in both the colon and the rectum of animal models. In addition, it presents the prebiotic activity.
