You still try to humanize and rationalize cancer cells.
They are not out to be better. They are not thinking, they are not in any way out to *do* anything.
Yes but for me these are just defective(madlike) ours. That day will be a good & holy day, when we shall achieve to correct them instead of killing them.
A cancer goes through a series of stages each of which can be their last and the length of which varies immensely
1: Initial mutation that relaxes the control of cell division
The cells multiply beyond what they would normally do, but are further harmless and can be stopped by simple things like physical resistance
2: Mutations in DNA repair in response to increase multiplication.
This is both the result of and the reaction to the multiplication defect. DNA repair in most tissues is relatively slow due to the slow replication rate. If cells replicate faster its more likely that this system gets subverted
3: Initial tumor.
With the loss of DNA control the cells can replicate faster and will start being destructive to their environment and also rapidly start accumulating various mutations, but are still linked to their point of origin
4: Metastatis
Due to the accumulation of mutations the cells at some point become able to detach from the tumor, enter the bloodstream and attach at a different point in the body.
One point is that cancer cells, being our cells, are not recognized by immune cells as foreign, 2nd, they can also lose contacts with immune cells due to their mass(outer cells in a tumor are recognized but inner ones not). I am not sure if any defect in adhesion system can also interfere immune cells to recognize cancer cells at any stage. Ok?
Now whatever the case, upto what stage/mutaions, cancer cells can be corrected or killed by our body mechansms if they are free or exposed?
Although at stage 3 and 4 in theory there is a chance the surface of the cells will alter to such a degree that the patients immune system will respond to them, this is by no means a given, and there is always the possibility that the cells the immune system recognizes and destroys are not the ones actually doing the damage. But all of this is the result of a cascade of mutations and not any conscious decision of the cancer cells. A great many get stuck in stage one and never become dangerous.
Do you mean that those who are not doing damage are still cancer cells but to lesser degree?
Is it always better that mutated cells(partially & completely) remain stuck or at any iinitial stage, if they are unbound, then they can be better handled by our defence mechanisms?
I realize that this is a simplification, but I really don't know any way to make it more clear without the need for you to truly immerse yourself in genetics and human biochemistry. At some point such knowledge in necessary if you want to know more about the mechanisms underlying cancer. This is not some secret way to keep knowledge from the layman, but its like trying to explain quantum mechanics to someone who has never had more maths than what is given in high school, or asking someone to build a building when you've never had more than standard woodcraft.
I do read a lot. While discussing, I do read a lot before posing & after posting, when I get some idea. But I feel text book readings may give you an idea in theory where you can locate any required information because it may be beyong a capacity of brain to really keep everything in it esp. at looking on so much & daily increasing understandings. Moreover, one may read & remember, but may not be able to study & effect by compiling everything at a time. I do observed that many understandings are there but they are quite sacattered-- even in mind. So compiling these is very necessary for the justified & effective knowledge. Moreover, I get many brainstorming clues from different & uncommon source about many unclear understandings, therefore want to comply with current understandings. Probably if we could make things simple & clear, it can help better.
I think you have not seen one of may yesterday's post. Pls llok & reply.
Best regards.
