Questions: Angiogenesis in Cancer

Hello,


I have following thoughts about Angiogenesis & request you to awnser
these after serious thinking:-


When cancer is in tumor stage it is considered that cancer cell can
encourage Angiogenesis for their nutrition, multiplication & spread.
But, I think that there can be two conditions related to it.


1.On naturally improved/biologically medicated immunity:- when a person
gets cancer, our immune system should be trying to kill/correct the
cabcer cells. But when our immune system couldn't handle these due to
required immune strength, cancer cells then may opt to arrest/encapsule
these in tumor etc.in cansiderations of (a)to starve them by inhibiting
blood supply or their respiration or nutrients (b)to restrict & resist
there growth & spread (c)to hold them in encapsuled/tumor state &
pursue to improve the immunity or wait for right time/immunity level,
when it can handle/kill thise cancer cells.


2.On weakening of immunity (natural or otherwise):- It may encourage
cancer cells to multiply & spread as progress of disease. I can't say
whether it can be Angiogenesis oriented or not?


Now my questions are:


1.Are cancer cells or other disease causing agents in tumor/latencies
capable of encouraging Angiogenesis, in view of that it os our body's
immune defence mechanism?


2. Can it be thought/possible that Angiogenesis is an immune defence
mechanism "On naturally improved/biologically medicated immunity" as I
described above, either to transport immune agents in tumor to kill
them OR to encourage them to resurface/take out from tumor for exposure
to immune system for killing them?


3. Can it be also thought that Angiogenesis may not be possible "On
weakening of immunity (natural or otherwise)" as I described above?


In short, can it be dynamically thought that, somewhat spread or
resurfacing of cancer cells & Angiogenesis can occur on improved
immunity to kill those as a "direction towords cure" instead of
"direction towords progress of disease"? This aspects may also be
thought for other latencies.

I think it is nowhere clearly mentioned, what happens when a person
with latent infections or cancer strengthened his immune system,
naturally, at some later date? Can it handle/cure latencies & cancer?

Best wishes.
