Two months after shingles, cancer is basically impossible because shingles is a viral infection, while cancer is a malignant tumor, and the two are not necessarily related. Unless the immunity of the patient with shingles is particularly low and a malignant cancer occurs at the same time, it is possible. For herpes zoster, it is very important to improve the immunity of the body, such as static dose of Kangai injection, thin glucose peptide injection or sodium deoxynucleotide injection, as well as intramuscular injection of BCG polysaccharide, and oral administration of thymidine enteric capsule, mushroom mushroom polysaccharide tablets or pidomod injection, etc. Treatment of herpes zoster requires oral antiviral drugs such as vaxilovir hydrochloride, and cancerous lesions need to be treated in the relevant oncology department.
