Cancer is a disease which is caused by the abnormality in the cell growth cycle mechanism which leads to the continuous division of cells without differentiation and dedifferentiation.
This leads to the formation of a group of undifferentiated cells called a tumor. The tumour cells lose the property of contact inhibition and thus spread to other parts of the body. They require nutrients to grow so they induce the formation of blood vessels.
Thus, all the options are correct.
