# Cancer in disguise: a parasite within

## TL;DR

This paper compares cancer cells to parasitic worms, suggesting they use similar strategies to survive and grow within the host.

## Contribution

The paper introduces the novel idea that cancer cells mimic parasitic helminths in their survival tactics.

## Key findings

- Cancer cells may use helminth-like strategies for immune evasion and tissue remodeling.
- Type-2 immune responses, linked to anti-parasitic defense, might also combat cancer.
- The parasitic nature of cancer challenges traditional views of oncogenesis.

## Abstract

Cancer does not simply develop unchecked—it strategically exploits its host with parasitic precision. From immune evasion to tissue remodeling, cancer cells mirror the survival strategies of parasitic helminths. This resemblance suggests that malignant cells have co-opted deeply conserved, evolutionarily honed tactics used by parasites to persist within their hosts. By mimicking helminths, cancer cells may also engage type-2 immune responses, traditionally associated with anti-parasitic defense, as part of the host’s attempt to control their expansion. Such parallels could also help explain why type-2 immunity, once considered tumor-promoting, has recently emerged as a potential source of tumoricidal activity. In this Perspective, we explore mechanistic parallels between cancer and helminth infection. Recognizing the parasitic nature of cancer cells not only challenges established models of oncogenesis but also reveals mechanisms that could be leveraged for therapy.

This Perspective highlights mechanistic parallels between cancer and helminth infection in migration, immune modulation and evasion.
