Developing new drugs takes years, and it can be expensive. In the meantime, there are a number of existing medications that have been proven effective in treating certain cancers. One of these drugs is fenben, which has long been used to treat parasites, particularly rodent pinworms, and it may be effective for treating human cancer as well.

A Facebook user called Joe Tippens was diagnosed with a rare form of large B-cell lymphoma in 2016. He began posting on his blog Get Busy Living about the treatment he was receiving for his disease, and people started following his protocol, which included fenbendazole, vitamins, and other supplements. He continues to post updates about his health, and he has not had a recurrence of his cancer since 2021.

Researchers have found that fenbendazole, which has been used to treat parasites in animals, works as a cancer treatment by disrupting the cellular signaling pathways involved in cell growth and proliferation. It also interferes with the availability of glucose, which is required for cancer cells to grow and proliferate. It has been shown to suppress tumor growth in xenografts (human cancer cells implanted into mice) and reduce the radiation response of tumor-bearing mice to irradiation.

The research shows that fenbendazole reduces tumorigenicity in both in vitro and in vivo tests by altering the microtubule structure of cancer cells, thus destabilizing them and inhibiting cell growth. It also decreases the expression of glut-4 transporter and hexokinase II, both of which promote glycolysis. Moreover, it increases the expression of p53, which is a potent regulator of glucose uptake, and it inhibits the enzymatic activity of glycolysis-related proteins.  fenben cancer treatment
