That is not entirely true... The prevalent chemotherapy is detrimental to cells all over the body and it has no way of distinguishing cancel cells vs non-cancer cells.
Targeted therapies are different and are becoming more widely used but are still small in percentage of patients compared to "classic" chemotherapy.
- PeterisP 6y ago"the prevalent chemotherapy is detrimental to cells all over the body" I'm not a doctor, but isn't the case that the prevalent chemotherapy is detrimental to new/growing cells all over the body, which is a way of distinguishing cancer cells (and a few types of tissue e.g. hair) vs most types of non-cancer cells?
- peterdemic 6y agoYes, that's correct! My bad for not being more clear!
- TrackerFF 6y agoQuite some time I had classes on this - but I believe chemo (some at least?) is designed to attack cells with same growth-rate as cancer cells. So they're not attacking just everything in a non-discriminatory fashion - but cells with similar growth as cancer cells, become collateral damage, so to speak. This is why some chemo will result in for example hairloss; Because the cancer you're being treated for, has the same growth rate as the cells in your hair - and thus the chemo will also kill those cells.
