If medical technology somehow gets to the point where amongst other things the anus can be used as a sex object without the threat of disease, instead of what it was meant for: deposing of human waste, then you sodomites will have beat God and His design for human sexuality.
Don't hold your breath boyz, as God doesn't lose.
Funny you should mention that.
I have a friend who is a doctor.
His brother is a lawyer, who is dying of cancer,
which started in the colon, and (perhaps even because of a biopsy)
spread quickly to the liver, and from there to the lungs.
In spite of all the great advances, I have watched carefully
as these two have consulted the best specialists and experts,
and taken various decisions along the way which appeared at the time
to be the best ones, and yet, the disease marches on,
controlled, slowed, but inevitably progressing to a final end.
Money was no object, nor medical expertise, nor apparent wisdom,
yet, each decision in hindsight did not seem to be either the right one,
or effective against the progress of the disease.
I doubt there is any cure at all possible,
unless it is the old ones, which no one dares try:
Fasting and Praying.
But obviously preventative medicine would have been best:
(1) Keeping the Food Laws.
(2) Keeping the Moral and Ethical Laws of God.
These are the best protection against misfortune,
although even they are no guarantee of divine protection,
and of course, ...everybody dies. Its how you live that matters.
Being an out of control addict of drugs or sexual perversion or violence,
these have only one end.
If you instead dedicate your life to helping others,
and obeying God's wisdom, guidance and laws,
and accepting God's terms of salvation,
you can have hope in this life and the next also.
