Managing Cancer Fever

After the pre-consultation the treatment follows three stages. See Table 1 – Light Therapy Stages. At each stage we monitor the milestones and inform patients when they can move to the next stage.

STAGE 1 – Cancer Fever Induction

Cancer is often a silent killer hardly felt. The power of the light reveals its true presence. The profound shock patients experience

when this happens is impossible to imagine in advance. “Cancer Fever” appears after the first application of light. The cancer may start to hurt or flue like symptoms may appear. There are often other signals coming from the cancer when fever occurs.
Cancer Fever is easily measured using a thermometer or a smart phone add-on. It shows that the light therapy is working, and the immune system is fighting the cancer. The amount of light needs to be balanced. When too much light is given, the cancer fever becomes too strong and the patient will struggle with exhaustion. On the other hand, when too little light is given, the cancer remains a threat. We guard the boundaries to ensure that neither too much nor too little light is used.
The induction stage ends when patients become comfortable with cancer fever


STAGE 2 – Cancer Fever Maintenance

Once patients trust themselves to use the lamp, they can maintain the cancer fever in stage 2. Patients discover the bearable lamp exposure. The maintenance stage ends when the cancer fever can no longer be induced. Sometimes the immune response gets too strong. For example, with abdominal cancer a patient may become nauseous. There are two ways to control such side effects. One is to continue with less light. Alternatively, a corticoid drug can be used to suppress the immune response. When cancer marker measures such as PSA start to fall back, the cancer is in regression. When PSA measures become normal a patient can elect to have a PET-CT scan to confirm complete regression. The Stage 2 of Cancer Fever ends when scans no longer detect the cancer.

STAGE 3 – Cancer Fever End Game

Some patients want to reduce the chance of recurrence although cancer is no longer detectable on scans. We believe it is necessary because it likely a few cancer cells will remain, some dormant. The objective of the cancer end game is to remove these cells with a one or more further cycles of light therapy.


Regular check-ups are recommended. If in the future the cancer recurs, or another cancer arises, there are no drawbacks to repeated light therapy treatments.
