Unformatted text preview: tion is destroyed, the cancer will
no longer spread
Radiation Therapy-X Rays, focused upon the cancers site,
X rays react with water in cells and disrupt DNA structure,
replication, cell division
Advantage - Slows tumor growth
Disadvantage- also damage normal cells
Chemo-drugs used to battle cancer
Pro: slows tumor growth
Con: can also damage normal cells (side effects)
Other Chemo drugs - recall use of thalidomide and liposomal nanomedicines in cancer
Adrianmycin - stops DNA from unwinding correctly which
results in disruption of DNA replication and no new cancer
Vincristine (from the rosy periwinkle ﬂower)
Taxol - from paciﬁc Yew Tree, both anti microtubule agents
These are natural plant extracts that inhibit spindle ﬁber formation, which results in disruption
of mitosis and no new cancer cells
Possible cures? Use bacteria, insert Genome, ﬁnd chemical pathway that produces natural
cures, blocking the inhibition site on cancer cell or protein
from deep water sponges with anti tumour properties, research is ongoing.
