testicular cancer 

According to the Bible, (Samuel 5:6-9) testicular cancer was one of God's many pestilences.

But after they had moved it, the LORD's hand was against that city, throwing it into a great panic. He afflicted the people of the city, both young and old, with an outbreak of tumors.
And it was so, that, after they had carried it about, the hand of the LORD was against the city with a very great destruction: and he smote the men of the city, both small and great, and they had emerods in their secret parts.

This isn't the only mention of testicular cancer: if the repeated use of 'hand' didn't tip you off; the Bible(s) is/are very repetitive

Kid Named Cancer 

Cancer was an amazing kid. He protec, he attac, but most importantly, he attac himself. Ever since the death of Technoblade, the #f*ckcancer community has grown, so much hate on him just because of his name, he could no longer go into society anymore because of this. For the past 9 days, he's been a massive nerd, it caused him to say unimaginable things, like "Minions 2: The Rise of Gru is a kids movie 🤓🤓🤓" and " Please Stop pulling My Ribs™ out 🤓🤓🤓" and just a few hours ago, he took his own life.

Bsishahsjja: i Know Technoblade is sad and all, but we need to respect Kid Named Cancer™
