Shingles is not a symptom of the early stages of cancer, they are different diseases and should not be confused. However, if you feel sick, you should go to the hospital in time. Herpes zoster is a disease caused by the varicella zoster virus, which can be characterized by edematous erythema distributed unilaterally in strips and blisters distributed in clusters, accompanied by tingling and burning sensation of the skin, enlarged lymph nodes, and fatigue and weakness. After diagnosis, antiviral drugs such as acyclovir and vasiclovir can be applied as prescribed by the doctor. Cancer is a malignant disease caused by a combination of internal and external factors such as heredity and environment, and some cancer patients are prone to shingles due to decreased immunity. However, there is no clear correlation between the two. The presence of shingles should be promptly consulted and treated with medication as prescribed by the doctor.
