Other cheap, simple, and in some cases more available ways to fight cancer include:

A healthy, low-sugar diet with plenty of organic veggies

Fish oil

Omega-3 That Poison for Tumors 3D tumors that disintegrate within a few days thanks to the action of a well-known Omega-3 (DHA, found mainly in fish) — this is the exceptional discovery by University of Louvain. Hungry for fatty acids, tumor cells in acidosis gorge themselves on DHA but are unable to store it correctly and literally poison themselves. The result? They die. Credit: Copyright UCLouvain

So-called “good fatty acids” are essential for human health and much sought after by those who try to eat healthily. Among the Omega-3 fatty acids, DHA or docosahexaenoic acid is crucial to brain function, vision, and the regulation of inflammatory phenomena.

In addition to these virtues, DHA is also associated with a reduction in the incidence of cancer. How it works is the subject of a major discovery by a multidisciplinary team of University of Louvain (UCLouvain) researchers, who have just elucidated the biochemical mechanism that allows DHA and other related fatty acids to slow the development of tumors. This is a major advance that has recently been published in the prestigious journal Cell Metabolism.

And much, much more: A large number of supplements have anti-cancer properties, including some supplements that are well known only for some other benefit; for instance, cranberry extracts are known for preventing and stopping urinary infections, but they ALSO help prevent and fight cancer:

Cranberries are rich in bioactive constituents reported to influence a variety of health benefits, ranging from improved immune function and decreased infections to reduced cardiovascular disease and more recently cancer inhibition. A review of cranberry research targeting cancer revealed positive effects of cranberries or cranberry derived constituents against 17 different cancers utilizing a variety of in vitro techniques, whereas in vivo studies supported the inhibitory action of cranberries toward cancers of the esophagus, stomach, colon, bladder, prostate, glioblastoma and lymphoma. Mechanisms of cranberry-linked cancer inhibition include cellular death induction via apoptosis, necrosis and autophagy; reduction of cellular proliferation; alterations in reactive oxygen species; and modification of cytokine and signal transduction pathways. Given the emerging positive preclinical effects of cranberries, future clinical directions targeting cancer or premalignancy in high risk cohorts should be considered.

Were I fighting cancer, I'd take a high (but carefully-considered and researched) dose of MANY supplements, plus drugs such as HCQ, IVM, Cimetidine, and would be very careful with my diet.

Of course, that's just me. This isn't advice and if it were, it might be worth exactly what you're paying for it: nothing. Do your own research, etc.
