Thank you for your query at DoctorSpring.com
I understand your concern.
Cancer can spread from one part of the body to other through :
1) Lymph node dissemination.
2) Through hematogenous ( blood dissemination - through veins or arteries ). Also the sites should have the same common source of blood supply for the dissemination to occur ( for example portal vein in abdomen )
So as a result of fall cancer won't pass from one site to the other.
Feel free to discuss further,
Patient replied :
Could a person withe stage 4 lung cancer have a breathing rate between 95 an 100%?
Stage 4 lung cancer mostly in cases of Non small cell lung cancer indicates that both the lungs have been involved and there is pleural effusion in both the lungs.
In such a situation the breathing will be affected, and the patient will need oxygen support.
So it won't be 95-100 %, if not on nebulisation.
