Basic premise
Kill cancer with a deadly virus (that's curable of course)
Such as small pox, or some other one.
Inject virus either directly into tumor, or into blood stream. If in blood stream, program virus to attack certain proteins only the cancer cells have. Once the virus is inside the cancer cell it will multiply and explode the cancer cell. Your immune system will do the rest.
Warning: side effects are to be expected, such as high fever and extreme headaches.
After about a month, you are good to go. No more cancer. Also, get that virus cleared up after.
Peace to all.
Immunotherapy, retroviral gene therapy, T-cell therapy, and countless other approaches to tackle cancer the way you describe are already in development, and some of them are starting to make it to the market. I'm sure Dala knows more about this, but I talk to cancer researchers whenever I get the chance because I'm interested in tracking medical (and other technological) developments, and there is a lot of optimism right now that most cancers will be a lot more manageable within the next couple of decades.
This is being done lots. A woman in my lab is working with tobacco mosaic viruses with fusogenic components in its membrane that are designed to contain ligands for receptors that are overexpressed in cancerous cells. Gastrin Release Peptide Receptor & Bombesin are the ones we work with. The lab next-door is pretty much 100% a virology & oncology lab.
The problem with designing viral vectors to kill off cancerous cells (through any variety of mechanisms) is the fact that cancer is insanely heterogenous. Even within 'groups' like prostate cancer. With where we are at now, we would pretty much need to personalize the viral vector based on the genomics/proteomics of the given cancer that a given individual is suffering from.
It's definitely promising, but we are years away. T-Cell therapy has also shown a lot of promise-- but again, only with certain diseases/certain contexts.
The biggest challenge with cancer is its heterogeneity-- even a primary tumour in and of itself is heterogenous genetically. What treatments work for one part of the tumour won't necessarily work for another part. It's tough. Heterogenous genetics means heterogeneous protein expression. Heterogenous protein expression can make you viral treatment 100% obsolete.
EDIT: Also if you pierce a tumour (as is done in biopsies) you're increasing the probabilities of metastasis; if you inject into the bloodstream, it's rather difficult to have a moiety on your vector that is able to localize to tumour tissues of all different types of cancer.
