You must be very gullible to believe your "friend's" totally
unsupported comments!
Are you sure this person is your friend?
No known hepatitis form is caused from an airborne virus and the occasional exposure to substances in that attic cannot cause nor dramatically contribute to cancer.
Cancer takes many years to develop in most circumstances.
How do you know it is cancer or something?
You might have some breathing and anxiety related issue and if the symptoms or your concerns are significant, you should seek a medical evaluation.
I hope this helps.
Best wishes,
