cancer treatment

1.  s it true that if someone goes through cancer treatment, people get side effects like warts on their hands and face and aslo a cit (I don't know if I spelled it right).

This guy told me that he got lung cancer and he was coughing really bad and after two weeks sitting next to him and i started coughing.  On top of that I also gave him a ride and during the ride he coughed really, hard and alot and I felt like I breathed some of his stuff in my lungs and I felt sick the next few days.  

2. Can I catch cancer from breathing in his stuff?  I meant the virus that causes cancer.  I understand cancer isn't contangious but can I catch the hpv from his caugh?  

3. Some cancers are caused by viruses and are those viruses air borne?

4. Should I get myself checked out?  The cough had gone away but I still feell an itch in my through and it has been a few weeks now.

You cannot catch Cancer from another person. You can be at minimal risk if someone in your family has gotten Cancer. You see some Cancers can hide inside you for years and years and never come out. Hereditary. You have to be aware of Carsigens these are Cancer causing agents. Asbestos, Aerisols, etc... You may have caught a Cold. If this is the only symptom you are experiencing maybe a good cough medicine.  You can also just have a regular doctors appt and they can diagnose you properly. It also maybe you just need some Antibiotics. Good luck and stay positive. Your brain is also a good healer. Think positive, think healthy. It does work. It worked for me.
