Forms of low-dose chemotherapy

The following forms of low-dose chemotherapy have been proposed. They are not always widely available treatments at hospitals.


Oral low-dose chemotherapy

Patients are given chemotherapy drugs orally very frequently. This approach can be very effective for some cancers and can minimize side effects for some people. More patients are using oral chemotherapy than ever before.

Although yet to be proven, insulin potentiation therapy (IPT) proponents suggest that

By using the very same mechanisms that cancer cells use to grow and kill people, proponents believe IPT channels the chemotherapy drug directly inside the cancer cells leaving normal cells alone.

There have been several attempts to use insulin in a variety functions that have proven ill-advised. In biological cancer therapies, an insulin potentiation therapy can be used to administer mandelonitrile (B17) as a pre step to an IPT low-dose Chemotherapy.


Research

There are many other researchers looking for low-dose chemotherapy treatments.
