I think that all types of cancer are chiefly result from microbial causes either changing in normal bacteria flora or due to the action of pathogenic microbes.
almost of cancers occur after birth no one born with cancer and no one born with bacterial flora .
so I suggest that alterations that affect the normal functions of that bacteria may lead to cancer and pathogenic microbes may cause cancer due to their victory when they compete the commensal flora .
wait your discussion about the theory mentioned above and I am looking for institution willing to support me to confirm my theory as doctorate project.
