Just reminder, there is no such thing as a "cure for cancer". There are over 200 distinct types of cancer, and there will never be a silver bullet treatment that will "cure" all of them. That being said, "Big Pharma" is not trying to block the treatment of these, and there are now numerous types of cancers that can be treated with greatly reduced fatality rates that 20 years before.
This speaks to the naiveté of a 17 year old, gifted or not. This should be a slap on the wrist, if there were real bio hazard risks to neighbors and surrounding properties.
Otherwise, let kids be kids. Nurture curiosity. Encourage critical thinking.
