The virus versions that cause visible, palpable warts do not cause cancer. Tonsils do not metastasize, the cancer cells in them do. Tonsil tissue is not smooth by nature, the tosillar crypt, is actually convoluted with folds and crevices in it. You should be able to feel your lymph nodes when they are normal, and they are not a uniform size in all people. Nodes that have become involved in the cancer process are firm/hard, fixated in place, (you can't push them around), and painless.
