There is really no way to remove the cancer causing agents from tobacco and still have tobacco. They are all generally the same when it comes to the chemicals they contain.
The byproducts of burning vegetable materials almost always contain some cancer-causing agents.
Retroviruses are a specific class of virus that infect animals and people by writing their genetic code into the DNA of the animal or human host. Some (but not all) retroviruses cause cancer, either by directly interfering with a part of the host's DNA that prevents cancer or by encouraging the expression of a part of the host's DNA that starts or enhances cancer.
It is possible that some foods can help promote cancer. Food that are processed are known to have cancer causing agents. Certain other foods carry carcinogens.
Retroviruses are a type of virus that contain RNA as their genetic material and use an enzyme called reverse transcriptase to convert their RNA into DNA once inside a host cell. This DNA is then integrated into the host's genome and can be replicated along with the host cell's DNA. Examples of retroviruses include HIV and some types of cancer-causing viruses.

Since carcinogens are cancer-causing agents, any release of carcinogens will increase, not decrease, cancer risk. Avoiding and reducing carcinogens will decrease the risk of cancer.
