     Clinically, hypertumors could be related to several paradoxical classes of tumors which, despite showing an aggressive histology, tend to spontaneously regress, such as some cases of neuroblastoma.

     In particular, one will recognize a hypertumor not just as regions of nutrient deficiency but as regions of nutrient deficency that always correlate with invading cells displaying cytological or genetic features of aggressive proliferation.

     They argue that tumors must be drastically larger in larger animals to be lethal, giving the hypertumor more time to grow and force the parent tumor to become necrotic.

   • 2016, Anca Ioviţă, The Aging Gap Between Species, →ISBN:

     According to the hypertumor hypothesis, as tumors grow larger, younger malignant cells take over their parents and outstrip them of their blood supply, resulting in tumor ischemic necrosis.
