[|Human|] My husband died at 33 with squamous cell carcinoma of the tongue, his sister was later diagnosed and now his Aunt, also childhood neighbor, grew up next door to these people has it. Have you ever heard of environmental containaments that can cause tongue cancer besides the obvious, alcohol and drugs?
[|AI|]  I am really sorry for the losses your family have suffered. Dear madam, reasons for oral cancers are many, amongst most common things we eat like, spices and especially chilly, besides the obvious reasons like nicotine (in any form, like chewable tobacco with or without lime). At this point i would like to knowledge that there is a strong familial predilection in many cases, as you have already mentioned that the other family members have also been diagnosed with this deadly disease. However besides these factors, chemical level of water and radiation of mobile and internet waves have also been enlisted as the cause of cancer.
