If Cancer were slow growing then there wouldn't be much need for treatment
It is because Cancer is a fast growing abnormal growth that takes over organ and other body parts
thus effectively destroying that function of the body. Cancer can spread from person to person
through blood transfusions. (Cancerous body parts were stolen from the dead and used for transplant ..
the patients then developed the cancer)
Cancer can be mild at first. But, once it grows to a large enough mass and metastasizes ... it will grow so
fast and cause so much pain and destruction. This is why early detection and treatment means the best outcome.
Wait too long and the cancer will have too strong a foothold that you will suffer and die a slow and painful death.
Back to topic: You wouldn't want to die by Cancer.
Try dying in your dream and maybe you will pass away in real life
