Shingles on the head belongs to a viral infection, cancer patients with reduced immunity can trigger shingles, but the occurrence of shingles is not necessarily suffering from cancer, so it is not the so-called cancer aura. Herpes zoster on any part of the body is related to infection with the shingles virus and autoimmune deficiency. If the immune system is lowered, it is easy to be infected with herpes virus, of course, the immune system of cancer patients will also be lowered, but the head infected with shingles virus does not necessarily mean that you are suffering from cancer. However, herpes zoster virus does not necessarily mean that you have cancer. If you have lowered immunity due to irregular life, too many late nights, too much pressure from work, or other diseases such as HIV infection, or if you are older, you are also susceptible to herpes zoster, so herpes zoster is not a so-called precursor of cancer. It is recommended that shingles be treated in a timely manner and in accordance with medical advice.
