Eli5: How do cancer drugs kill cancerous and precancerous cells?

804 views

My doctor has prescribed a chemo cream to treat several stubborn actinic keratosis areas on my face. I am supposed to use the cream on my entire face twice a day for 28 days. (Eeek !). My understanding is that the cream somehow gets into the cancerous cells (how?) and disrupts the cells ability to reproduce (how?). For a bonus..can you tell me why this process pushes all those nasty cells to the surface to die….making my face look like a living mutant zombie who didn’t fare well during the apocalypse!

Chemo drug – basically try to kill every cells that replicate too fast , which why they’re some side effect with hair, gut , skin etc which also replicating cells

targeted therapy – so they want the drug that targeted on unique part on cancer cell so it has less effect on normal cell (so hope for less side effect)

anti hormonal drug – some cancer like breast cancer are stimulated by hormone , blocking cancer cell from this hormones can help
