Will cancer always cause an elevated CRP & ESR? Throat cancer, lymphoma?

No. Elevated ESR and CRP are markers of inflammation, not cancer.

Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
