Solution

Carrying capacity-Cancerous cell have higher carrying capacity than normal cells and this property known to correlate with aggresiveness. Subsequent mutation makes it possible for cancerous cell to grow with increased carryng capacity that acheive by changing the microenvironment of the cell and thus the disease progress.

Population density- Its increases by ability of cancerous cells to adapt and poliferate by resistant phenotypes and tumour growth population will remain until all poliferative cells are killed.

Competition- In tunour ecosystem, tumour cells compete for space and nutrients but intruingly they may also produce growth factors to sustain tumour growth.

Natural selection-Its bring evolutionary change by favouring differential reproduction of genes that produce changes in gene frequency from one generation to the next and creates new adaptive relation between population and environment, by favouring gene combination ,rejecting other genes and concstantly moulding and modifing gene pool.
